Jan Jongboom / Mbed OS mdot_two_way

Two way data over LoRaWAN using Multitech mDot

Dependencies:   libmDot-mbed5

This is example firmware for the Multitech mDot. It demonstrates how to:

  • Do two-way data.
  • Sleep aggressively and only wake up when the wake-up pin is triggered.
  • Handle errors, retries and duty cycle errors.
  • Cache data in non-volatile storage.

Based on mbed OS 5.1, hard faults against mbed OS 5.3 unfortunately. Can be compiled with GCC and ARMCC (but not IAR).

To do a new transmission, short pin D6 / PA_1.
