+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+### Async TCP Library for ESP32 Arduino
+
+This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP32 MCUs.
+
+This library is the base for [ESPAsyncWebServer](https://github.com/dvarrel/ESPAsyncWebServer)
+
+## AsyncClient and AsyncServer
+The base classes on which everything else is built. They expose all possible scenarios, but are really raw and require more skills to use.

+# Servo Library for ESP32
+
+Specifically for the V3.0.0 of Arduino ESP32. All ADC's have been updated to work correctly with the new release
+
+https://github.com/espressif/arduino-esp32/releases
+
+This library attempts to faithfully replicate the semantics of the
+Arduino Servo library (see http://www.arduino.cc/en/Reference/Servo)
+for the ESP32, with two (optional) additions. The two new functions
+expose the ability of the ESP32 PWM timers to vary timer width.

+## Library Description:
+```
+    Servo - Class for manipulating servo motors connected to ESP32 pins.
+    
+    int attach(pin )  - Attaches the given GPIO pin to the next free channel
+        (channels that have previously been detached are used first), 
+        returns channel number or 0 if failure. All pin numbers are allowed,
+        but only pins 2,4,12-19,21-23,25-27,32-33 are recommended.
+    
+    int attach(pin, min, max  ) - Attaches to a pin setting min and max 
+        values in microseconds; enforced minimum min is 500, enforced max
+        is 2500. Other semantics are the same as attach().
+    
+    void write () - Sets the servo angle in degrees; a value below 500 is
+        treated as a value in degrees (0 to 180). These limit are enforced,
+        i.e., values are constrained as follows:
+            Value                                   Becomes
+            -----                                   -------
+            < 0                                        0
+            0 - 180                                  value (treated as degrees)
+            181 - 499                                 180
+            500 - (min-1)                             min
+            min-max (from attach or default)         value (treated as microseconds)
+            (max+1) - 2500                            max
+    
+    void writeMicroseconds() - Sets the servo pulse width in microseconds.
+        min and max are enforced (see above). 
+        
+    int read() - Gets the last written servo pulse width as an angle between 0 and 180. 
+    
+    int readMicroseconds()   - Gets the last written servo pulse width in microseconds.
+    
+    bool attached() - Returns true if this servo instance is attached to a pin.
+    
+    void detach() - Stops an the attached servo, frees the attached pin, and frees
+        its channel for reuse.  
+```
+
+### **New ESP32-specific functions**
+ 
+```
+    setTimerWidth(value) - Sets the PWM timer width (must be 16-20) (ESP32 ONLY);
+        as a side effect, the pulse width is recomputed.
+
+    int readTimerWidth() - Gets the PWM timer width (ESP32 ONLY) 
+```
+ 
+### Useful Defaults:
+
+default min pulse width for attach(): 544us
+
+default max pulse width for attach(): 2400us
+
+default timer width 16 (if timer width is not set)
+
+default pulse width 1500us (servos are initialized with this value)
+
+MINIMUM pulse with: 500us
+
+MAXIMUM pulse with: 2500us
+
+MAXIMUM number of servos: 16 (this is the number of PWM channels in the ESP32)

+ This example code is in the public domain.

+ modified 8 Nov 2013

+
+ modified for the ESP32 on March 2017
+ by John Bennett
+
+ see http://www.arduino.cc/en/Tutorial/Sweep for a description of the original code
+
+ * Different servos require different pulse widths to vary servo angle, but the range is 
+ * an approximately 500-2500 microsecond pulse every 20ms (50Hz). In general, hobbyist servos
+ * sweep 180 degrees, so the lowest number in the published range for a particular servo
+ * represents an angle of 0 degrees, the middle of the range represents 90 degrees, and the top
+ * of the range represents 180 degrees. So for example, if the range is 1000us to 2000us,
+ * 1000us would equal an angle of 0, 1500us would equal 90 degrees, and 2000us would equal 1800
+ * degrees.
+ * 
+ * Circuit: (using an ESP32 Thing from Sparkfun)
+ * Servo motors have three wires: power, ground, and signal. The power wire is typically red,
+ * the ground wire is typically black or brown, and the signal wire is typically yellow,
+ * orange or white. Since the ESP32 can supply limited current at only 3.3V, and servos draw
+ * considerable power, we will connect servo power to the VBat pin of the ESP32 (located
+ * near the USB connector). THIS IS ONLY APPROPRIATE FOR SMALL SERVOS. 
+ * 
+ * We could also connect servo power to a separate external
+ * power source (as long as we connect all of the grounds (ESP32, servo, and external power).
+ * In this example, we just connect ESP32 ground to servo ground. The servo signal pins
+ * connect to any available GPIO pins on the ESP32 (in this example, we use pin 18.
+ * 
+ * In this example, we assume a Tower Pro MG995 large servo connected to an external power source.
+ * The published min and max for this servo is 1000 and 2000, respectively, so the defaults are fine.
+ * These values actually drive the servos a little past 0 and 180, so
+ * if you are particular, adjust the min and max values to match your needs.

+
+* Notes on the implementation:
+* The ESP32 supports 16 hardware LED PWM channels that are intended
+* to be used for LED brightness control. The low level ESP32 code
+* (esp32-hal-ledc.*) allows us to set the PWM frequency and bit-depth,
+* and then manipulate them by setting bits in the relevant control
+* registers.
+*
+* Different servos require different pulse widths to vary servo angle, but the range is
+* an approximately 500-2500 microsecond pulse every 20ms (50Hz). In general, hobbyist servos
+* sweep 180 degrees, so the lowest number in the published range for a particular servo
+* represents an angle of 0 degrees, the middle of the range represents 90 degrees, and the top
+* of the range represents 180 degrees. So for example, if the range is 1000us to 2000us,
+* 1000us would equal an angle of 0, 1500us would equal 90 degrees, and 2000us would equal 180
+* degrees. We vary pulse width (recall that the pulse period is already set to 20ms) as follows:
+*
+* The ESP32 PWM timers allow us to set the timer width (max 20 bits). Thus
+* the timer "tick" length is (pulse_period/2**timer_width), and the equation for pulse_high_width
+* (the portion of the 20ms cycle that the signal is high) becomes:
+*
+*                  pulse_high_width  = count * tick_length
+*                                    = count * (pulse_period/2**timer_width)
+*
+*            and   count = (pulse_high_width / (pulse_period/2**timer_width))
+*
+* So, for example, if I want a 1500us pulse_high_width, I set pulse_period to 20ms (20000us)
+* (this value is set in the ledcSetup call), and count (used in the ledcWrite call) to
+* 1500/(20000/65536), or 4924. This is the value we write to the timer in the ledcWrite call.
+* If we increase the timer_width, the timer_count values need to be adjusted.
+*
+* The servo signal pins connect to any available GPIO pins on the ESP32, but not all pins are
+* GPIO pins.
+*
+* The ESP32 is a 32 bit processor that includes FP support; this code reflects that fact.

+/* 
+ A servo is activated by creating an instance of the Servo class, and passing
+ the desired GPIO pin to the attach() method.
+ The servos are pulsed in the background using the value most recently
+ written using the write() method.
+
+ The class methods are:
+
+ Servo - Class for manipulating servo motors connected to ESP32 pins.
+ int attach(pin )  - Attaches the given GPIO pin to the next free channel
+ (channels that have previously been detached are used first),
+ returns channel number or 0 if failure. All pin numbers are allowed,
+ but only pins 2,4,12-19,21-23,25-27,32-33 are recommended.
+ int attach(pin, min, max  ) - Attaches to a pin setting min and max
+ values in microseconds; enforced minimum min is 500, enforced max
+ is 2500. Other semantics same as attach().
+ void write () - Sets the servo angle in degrees; a value below 500 is
+ treated as a value in degrees (0 to 180). These limit are enforced,
+ i.e., values are treated as follows:
+ Value                                   Becomes
+ -----                                   -------
+ < 0                                        0
+ 0 - 180                             value (treated as degrees)
+ 181 - 499                                 180
+ 500 - (min-1)                             min
+ min-max (from attach or default)    value (treated as microseconds)
+ (max+1) - 2500                            max
+
+ void writeMicroseconds() - Sets the servo pulse width in microseconds.
+ min and max are enforced (see above).
+ int read() - Gets the last written servo pulse width as an angle between 0 and 180.
+ int readMicroseconds()   - Gets the last written servo pulse width in microseconds.
+ bool attached() - Returns true if this servo instance is attached.
+ void detach() - Stops an the attached servo, frees its attached pin, and frees
+ its channel for reuse).
+
+ *** ESP32-specific functions **
+ setTimerWidth(value) - Sets the PWM timer width (must be 16-20) (ESP32 ONLY);
+ as a side effect, the pulse width is recomputed.
+ int readTimerWidth() - Gets the PWM timer width (ESP32 ONLY)

+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+# ESPAsyncTCP 
+
+### Async TCP Library for ESP8266 Arduino
+
+For ESP32 look [HERE](https://github.com/dvarrel/AsyncTCP)
+
+This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP8266 MCUs.
+
+This library is the base for [ESPAsyncWebSrv](https://github.com/dvarrel/ESPAsyncWebSrv)
+
+## AsyncClient and AsyncServer
+The base classes on which everything else is built. They expose all possible scenarios, but are really raw and require more skills to use.
+
+## AsyncPrinter
+This class can be used to send data like any other ```Print``` interface (```Serial``` for example).
+The object then can be used outside of the Async callbacks (the loop) and receive asynchronously data using ```onData```. The object can be checked if the underlying ```AsyncClient```is connected, or hook to the ```onDisconnect``` callback.
+
+## AsyncTCPbuffer
+This class is really similar to the ```AsyncPrinter```, but it differs in the fact that it can buffer some of the incoming data.
+
+## SyncClient
+It is exactly what it sounds like. This is a standard, blocking TCP Client, similar to the one included in ```ESP8266WiFi```
+
+## Libraries and projects that use AsyncTCP
+- [ESP Async Web Server](https://github.com/dvarrel/ESPAsyncWebSrv)

+ * server is running (on port 7050) on one ESP, acts as AP, and other clients running on
+ * remaining ESPs acts as STAs. after connection establishment between server and clients
+ * there is a simple message transfer in every 2s. clients connect to server via it's host name
+ * (in this case 'esp_server') with help of DNS service running on server side.

+Changes for July 2019
+
+The operator "new ..." was changed to "new (std::nothrow) ...", which will
+return NULL when the heap is out of memory. Without the change "soft WDT"
+was the result, starting with Arduino ESP8266 Core 2.5.0. (Note, RE:"soft
+WDT" - the error  reporting may improve with core 2.6.) With proir core
+versions the library appears to work fine.
+ref: https://github.com/esp8266/Arduino/issues/6269#issue-464978944
+
+To support newer lwIP versions and buffer models. All references to 1460
+were replaced with TCP_MSS. If TCP_MSS is not defined (exp. 1.4v lwIP)
+1460 is assumed.
+
+The ESPAsyncTCP library should build for Arduino ESP8266 Core releases:
+2.3.0, 2.4.1, 2.4.2, 2.5.1, 2.5.2. It may still build with core versions
+2.4.0 and 2.5.0. I did not do any regression testing with these, since
+they had too many issues and were quickly superseded.
+
+lwIP tcp_err() callback often resulted in crashes. The problem was a
+tcp_err() would come in, while processing a send or receive in the
+forground. The tcp_err() callback would be passed down to a client's
+registered disconnect CB. A common problem with SyncClient and other
+modules as well as some client code was: the freeing of ESPAsyncTCP
+AsyncClient objects via disconnect CB handlers while the library was
+waiting for an operstion to  finished. Attempts to access bad pointers
+followed. For SyncClient this commonly occured during a call to delay().
+On return to SyncClient _client was invalid. Also the problem described by
+issue #94 also surfaced
+
+Use of tcp_abort() required some very special handling and was very
+challenging to make work without changing client API. ERR_ABRT can only be
+used once on a return to lwIP for a given connection and since the
+AsyncClient structure was sometimes deleted before returning to lwIP, the
+state tracking became tricky. While ugly, a global variable for this
+seemed to work; however, I  abanded it when I saw a possible
+reentrancy/concurrency issue. After several approaches I settled the
+problem by creating "class ACErrorTracker" to manage the issue.
+
+
+Additional Async Client considerations:
+
+The client sketch must always test if the connection is still up at loop()
+entry and after the return of any function call, that may have done a
+delay() or yield() or any ESPAsyncTCP library family call. For example,
+the connection could be lost during a call to _client->write(...). Client
+sketches that delete _client as part of their onDisconnect() handler must
+be very careful as _client will become invalid after calls to delay(),
+yield(), etc.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socioeconomic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+https://sidweb.nl/cms3/en/contact.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+  - Use: `lib_deps=ESP32Async/ESPAsyncWebServer` to point to latest version
+  - Use: `lib_deps=ESP32Async/ESPAsyncWebServer @ ^<x.y.z>` to point to latest version with the same major version
+  - Use: `lib_deps=ESP32Async/ESPAsyncWebServer @ <x.y.z>` to always point to the same version (reproductible build)
+
+## Dependencies
+
+### ESP32 / pioarduino
+
+```ini
+[env:stable]
+platform = https://github.com/pioarduino/platform-espressif32/releases/download/stable/platform-espressif32.zip
+lib_compat_mode = strict
+lib_ldf_mode = chain
+lib_deps =
+  ESP32Async/AsyncTCP
+  ESP32Async/ESPAsyncWebServer
+```
+
+### ESP8266 / pioarduino
+
+```ini
+[env:stable]
+platform = espressif8266
+lib_compat_mode = strict
+lib_ldf_mode = chain
+lib_deps =
+  ESP32Async/ESPAsyncTCP
+  ESP32Async/ESPAsyncWebServer
+```
+
+### Unofficial dependencies
+
+**AsyncTCPSock**
+
+AsyncTCPSock can be used instead of AsyncTCP by excluding AsyncTCP from the library dependencies and adding AsyncTCPSock instead:
+
+```ini
+lib_compat_mode = strict
+lib_ldf_mode = chain
+lib_deps =
+  https://github.com/ESP32Async/AsyncTCPSock/archive/refs/tags/v1.0.3-dev.zip
+  ESP32Async/ESPAsyncWebServer
+lib_ignore =
+  AsyncTCP
+  ESP32Async/AsyncTCP
+```
+
+**RPAsyncTCP**
+
+RPAsyncTCP replaces AsyncTCP to provide support for RP2040(+WiFi) and RP2350(+WiFi) boards. For example - Raspberry Pi Pico W and Raspberry Pi Pico 2W.
+
+```ini
+lib_compat_mode = strict
+lib_ldf_mode = chain
+platform = https://github.com/maxgerhardt/platform-raspberrypi.git
+board = rpipicow
+board_build.core = earlephilhower
+lib_deps =
+  ayushsharma82/RPAsyncTCP@^1.3.2
+  ESP32Async/ESPAsyncWebServer
+lib_ignore =
+  lwIP_ESPHost
+build_flags = ${env.build_flags}
+  -Wno-missing-field-initializers
+```
+
+## Important recommendations for build options
+
+Most of the crashes are caused by improper use or configuration of the AsyncTCP library used for the project.
+Here are some recommendations to avoid them and build-time flags you can change.
+
+`CONFIG_ASYNC_TCP_MAX_ACK_TIME` - defines a timeout for TCP connection to be considered alive when waiting for data.
+In some bad network conditions you might consider increasing it.
+
+`CONFIG_ASYNC_TCP_QUEUE_SIZE` - defines the length of the queue for events related to connections handling.
+Both the server and AsyncTCP library were optimized to control the queue automatically. Do NOT try blindly increasing the queue size, it does not help you in a way you might think it is. If you receive debug messages about queue throttling, try to optimize your server callbacks code to execute as fast as possible.
+Read #165 thread, it might give you some hints.
+
+`CONFIG_ASYNC_TCP_RUNNING_CORE` - CPU core thread affinity that runs the queue events handling and executes server callbacks. Default is ANY core, so it means that for dualcore SoCs both cores could handle server activities. If your server's code is too heavy and unoptimized or you see that sometimes
+server might affect other network activities, you might consider to bind it to the same core that runs Arduino code (1) to minimize affect on radio part. Otherwise you can leave the default to let RTOS decide where to run the thread based on priority
+
+`CONFIG_ASYNC_TCP_STACK_SIZE` - stack size for the thread that runs sever events and callbacks. Default is 16k that is a way too much waste for well-defined short async code or simple static file handling. You might want to cosider reducing it to 4-8k to same RAM usage. If you do not know what this is or not sure about your callback code demands - leave it as default, should be enough even for very hungry callbacks in most cases.
+
+> [!NOTE]
+> This relates to ESP32 only, ESP8266 uses different ESPAsyncTCP lib that does not has this build options
+
+I personally use the following configuration in my projects:
+
+```c++
+  -D CONFIG_ASYNC_TCP_MAX_ACK_TIME=5000   // (keep default)
+  -D CONFIG_ASYNC_TCP_PRIORITY=10         // (keep default)
+  -D CONFIG_ASYNC_TCP_QUEUE_SIZE=64       // (keep default)
+  -D CONFIG_ASYNC_TCP_RUNNING_CORE=1      // force async_tcp task to be on same core as Arduino app (default is any core)
+  -D CONFIG_ASYNC_TCP_STACK_SIZE=4096     // reduce the stack size (default is 16K)
+```
+
+If you need to serve chunk requests with a really low buffer (which should be avoided), you can set `-D ASYNCWEBSERVER_USE_CHUNK_INFLIGHT=0` to disable the in-flight control.
