Bleeding edge development version of the mDot library. This version of the library is not guaranteed to be stable or well tested and should not be used in production or deployment scenarios.

Dependents:   mDot_LoRa_CLASS_C_P2P

Fork of libmDot-dev by Multi-Hackers

Warning

Using libmDot 2.0.3 and above with an existing application may require a change in the MacEvent handler!
Compile applications with mbed v121 and mbed-rtos v116 libraries.

In AT Command Firmware remove line 803.

CommandTerminal/CommandTerminal.cpp

        delete[] info->RxBuffer;

Likewise, if your application is handling events from the library asynchronously.

---------------------------------------
Getting Started with the mDot Library
---------------------------------------

This README should get you started using the mDot library with your MultiTech mDot.

License information can be found in the accompanying LICENSE file.

The mDot header has documentation for all the public functions that will be useful to consumers of
the library.

The following source code provides an example application which configures the mDot, connects to a
MultiTech Conduit gateway with matching configuration, and sends data packets to the gateway.

NOTE: All applications built using the mDot library must include mbed-src instead of mbed and must
have the "newboards" beta token enabled.  This is to resolve a stack size issue that may be
encountered otherwise.  A fix is on its way to the regular mbed library, but these extra steps are
required until then.  To enable the "newboards" beta token, go to the page listed below, click
enable, and completely refresh your online compiler.
