Two way data over LoRaWAN using Multitech mDot
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.
