The current array of DM LoRaWAN devices comply with the 1.0.2 LoRaWAN specification. The stack is based on the Semtech reference stack, with one deviation:

  • There is no frame repetition support (NbTrans MAC command). This is deliberate, due to issues porting the reference stack. The implementation is not power friendly and not suitable to battery powered tracking devices.

The stack will change in future to fix the frame repetition requirement and comply with LoRaWAN 1.1.
