Library for LoRa communication using MultiTech MDOT.

Dependents:   mDot_test_rx adc_sensor_lora mDotEVBM2X mDot_AT_firmware ... more

Function documentation is in mDot.h

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.

Commit message:
Previous libmDot version "16:e4f80db195b6" has the wrong header files for mDot.h and mDotEvent.h. Use with mbed version 121 and mbed-rtos version 116.
