LoRaWAN MAC layer implementation

LoRAWAN-lib is a port of the GitHub LoRaMac-node LoRaWAN MAC layer implementation.

This library depends on the SX1276Lib or SX1272Lib radio drivers depending on the used mbed component shield.

This library depends also on some cryptographic helper functions as well as helper functions for the timers management. These can be found on the example projects under the system directory.

The example projects are:

  1. LoRaWAN-demo-72
  2. LoRaWAN-demo-76
  3. LoRaWAN-demo-NAMote72

The LoRaWAN specification specifies different ISM bands operating parameters. These are all implemented under the LoRaMac-board.h file.

In order to select which band to use, please change line 24 of board.h file provided on the examples projects as follows:


EU868

board.h

#define USE_BAND_868


US915

board.h

#define USE_BAND_915


US915 - Hybrid

board.h

#define USE_BAND_915_HYBRID


CN780

board.h

#define USE_BAND_780


EU433

board.h

#define USE_BAND_433
