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.

+---------------------------------------
+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.
