-### GNU LESSER GENERAL PUBLIC LICENSE
-
-Version 2.1, February 1999
-
-    Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-    51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-    
-    Everyone is permitted to copy and distribute verbatim copies
-    of this license document, but changing it is not allowed.
-
-    [This is the first released version of the Lesser GPL.  It also counts
-     as the successor of the GNU Library Public License, version 2, hence
-     the version number 2.1.]
-
-### Preamble
-
-The licenses for most software are designed to take away your freedom
-to share and change it. By contrast, the GNU General Public Licenses
-are intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.
-
-This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations
-below.
-
-When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
-We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-To protect each distributor, we want to make it very clear that there
-is no warranty for the free library. Also, if the library is modified
-by someone else and passed on, the recipients should know that what
-they have is not the original version, so that the original author's
-reputation will not be affected by problems that might be introduced
-by others.
-
-Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-When a program is linked with a library, whether statically or using a
-shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
-For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it
-becomes a de-facto standard. To achieve this, non-free programs must
-be allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-**0.** This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License"). Each
-licensee is addressed as "you".
-
-A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-"Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control
-compilation and installation of the library.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does and
-what the program that uses the Library does.
-
-**1.** You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a
-fee.
-
-**2.** You may modify your copy or copies of the Library or any
-portion of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
--   **a)** The modified work must itself be a software library.
--   **b)** You must cause the files modified to carry prominent
-    notices stating that you changed the files and the date of
-    any change.
--   **c)** You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
--   **d)** If a facility in the modified Library refers to a function
-    or a table of data to be supplied by an application program that
-    uses the facility, other than as an argument passed when the
-    facility is invoked, then you must make a good faith effort to
-    ensure that, in the event an application does not supply such
-    function or table, the facility still operates, and performs
-    whatever part of its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of
-    the application. Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-**3.** You may opt to apply the terms of the ordinary GNU General
-Public License instead of this License to a given copy of the Library.
-To do this, you must alter all the notices that refer to this License,
-so that they refer to the ordinary GNU General Public License, version
-2, instead of to this License. (If a newer version than version 2 of
-the ordinary GNU General Public License has appeared, then you can
-specify that version instead if you wish.) Do not make any other
-change in these notices.
-
-Once this change is made in a given copy, it is irreversible for that
-copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-This option is useful when you wish to copy part of the code of the
-Library into a program that is not a library.
-
-**4.** You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-If distribution of object code is made by offering access to copy from
-a designated place, then offering equivalent access to copy the source
-code from the same place satisfies the requirement to distribute the
-source code, even though third parties are not compelled to copy the
-source along with the object code.
-
-**5.** A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a work,
-in isolation, is not a derivative work of the Library, and therefore
-falls outside the scope of this License.
-
-However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License. Section
-6 states terms for distribution of such executables.
-
-When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
-If such an object file uses only numerical parameters, data structure
-layouts and accessors, and small macros and small inline functions
-(ten lines or less in length), then the use of the object file is
-unrestricted, regardless of whether it is legally a derivative work.
-(Executables containing this object code plus portions of the Library
-will still fall under Section 6.)
-
-Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-**6.** As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a work
-containing portions of the Library, and distribute that work under
-terms of your choice, provided that the terms permit modification of
-the work for the customer's own use and reverse engineering for
-debugging such modifications.
-
-You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
--   **a)** Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library. (It is understood that
-    the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
--   **b)** Use a suitable shared library mechanism for linking with
-    the Library. A suitable mechanism is one that (1) uses at run time
-    a copy of the library already present on the user's computer
-    system, rather than copying library functions into the executable,
-    and (2) will operate properly with a modified version of the
-    library, if the user installs one, as long as the modified version
-    is interface-compatible with the version that the work was
-    made with.
--   **c)** Accompany the work with a written offer, valid for at least
-    three years, to give the same user the materials specified in
-    Subsection 6a, above, for a charge no more than the cost of
-    performing this distribution.
--   **d)** If distribution of the work is made by offering access to
-    copy from a designated place, offer equivalent access to copy the
-    above specified materials from the same place.
--   **e)** Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-**7.** 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 not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
--   **a)** Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other
-    library facilities. This must be distributed under the terms of
-    the Sections above.
--   **b)** Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-**8.** You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-**9.** You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-**10.** Each time you redistribute the Library (or any work based on
-the Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-**11.** If, as a consequence of a court judgment or allegation of
-patent infringement or for any other reason (not limited to patent
-issues), conditions are imposed on you (whether by court order,
-agreement or otherwise) that contradict the conditions of this
-License, they do not excuse you from the conditions of this License.
-If you cannot distribute so as to satisfy simultaneously your
-obligations under this License and any other pertinent obligations,
-then as a consequence you may not distribute the Library at all. For
-example, if a patent license would not permit royalty-free
-redistribution of the Library by all those who receive copies directly
-or indirectly through you, then the only way you could satisfy both it
-and this License would be to refrain entirely from distribution of the
-Library.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply, and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-**12.** If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-**13.** The Free Software Foundation may publish revised and/or new
-versions of the 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
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-**14.** If you wish to incorporate parts of the Library into other
-free programs whose distribution conditions are incompatible with
-these, write to the author to ask for permission. For software which
-is copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-**NO WARRANTY**
-
-**15.** BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-**16.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-### END OF TERMS AND CONDITIONS
-
-### How to Apply These Terms to Your New Libraries
-
-If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms
-of the ordinary General Public License).
-
-To apply these terms, attach the following notices to the library. It
-is safest to attach them to the start of each source file to most
-effectively convey the exclusion of warranty; and each file should
-have at least the "copyright" line and a pointer to where the full
-notice is found.
-
-    one line to give the library's name and an idea of what it does.
-    Copyright (C) year  name of author
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-Also add information on how to contact you by electronic and paper
-mail.
-
-You should also get your employer (if you work as a programmer) or
-your school, if any, to sign a "copyright disclaimer" for the library,
-if necessary. Here is a sample; alter the names:
-
-    Yoyodyne, Inc., hereby disclaims all copyright interest in
-    the library `Frob' (a library for tweaking knobs) written
-    by James Random Hacker.
-
-    signature of Ty Coon, 1 April 1990
-    Ty Coon, President of Vice
-
-That's all there is to it!

-## FreeRTOS Tick Rate (Hz)
-
-You might notice that Arduino-esp32's `delay()` function will only work in multiples of 10ms. That is because, by default, esp-idf handles task events 100 times per second.
-To fix that behavior you need to set FreeRTOS tick rate to 1000Hz in `make menuconfig` -> `Component config` -> `FreeRTOS` -> `Tick rate`.

 ## Compilation Errors
 
 As commits are made to esp-idf and submodules, the codebases can develop incompatibilities which cause compilation errors.  If you have problems compiling, follow the instructions in [Issue #1142](https://github.com/espressif/arduino-esp32/issues/1142) to roll esp-idf back to a known good version.

-## Using esp32-arduino-lib-builder to compile custom libraries
-
-Espressif has provided a [tool](https://github.com/espressif/esp32-arduino-lib-builder) to simplify building your own compiled libraries for use in Arduino IDE (or your favorite IDE).
-To use it to generate custom libraries, follow these steps:
-1. `git clone https://github.com/espressif/esp32-arduino-lib-builder`
-2. `cd esp32-arduino-lib-builder`
-3. `./tools/update-components.sh`
-4. `./tools/install-esp-idf.sh` (if you already have an $IDF_PATH defined, it will use your local copy of the repository)
-5. `make menuconfig` or directly edit sdkconfig.
-6. `./build.sh`
-
-The script automates the process of building [arduino as an ESP-IDF component](https://github.com/espressif/arduino-esp32/blob/master/docs/esp-idf_component.md).
-Once it is complete, you can cherry pick the needed libraries from `out/tools/sdk/lib`, or run `tools/copy-to-arduino.sh` to copy the entire built system.
-`tools/config.sh` contains a number of variables that control the process, particularly the $IDF_BRANCH variable.  You can adjust this to try building against newer versions, but there are absolutely no guarantees that any components will work or even successfully compile against a newer IDF.

-   ESPNOW - Basic communication - Master
-   Date: 26th September 2017
-   Author: Arvind Ravulavaru <https://github.com/arvindr21>
-   Purpose: ESPNow Communication between a Master ESP32 and a Slave ESP32
-   Description: This sketch consists of the code for the Master module.
-   Resources: (A bit outdated)
-   a. https://espressif.com/sites/default/files/documentation/esp-now_user_guide_en.pdf
-   b. http://www.esploradores.com/practica-6-conexion-esp-now/
-
-   << This Device Master >>
-
-   Flow: Master
-   Step 1 : ESPNow Init on Master and set it in STA mode
-   Step 2 : Start scanning for Slave ESP32 (we have added a prefix of `slave` to the SSID of slave for an easy setup)
-   Step 3 : Once found, add Slave as peer
-   Step 4 : Register for send callback
-   Step 5 : Start Transmitting data from Master to Slave
-
-   Flow: Slave
-   Step 1 : ESPNow Init on Slave
-   Step 2 : Update the SSID of Slave with a prefix of `slave`
-   Step 3 : Set Slave in AP mode
-   Step 4 : Register for receive callback and wait for data
-   Step 5 : Once data arrives, print it in the serial monitor
-
-   Note: Master and Slave have been defined to easily understand the setup.
-         Based on the ESPNOW API, there is no concept of Master and Slave.
-         Any devices can act as master or salve.
