Hi

lora-mqtt is not compatible with LoRaWAN Specifications, it's a binary-to-MQTT translator for our own MAC layer (https://github.com/unwireddevices/RIOT/tree/unwired/unwired-modules, simplified LoRa MAC layer for small-scale projects with up to 500 nodes on a network and a single-channel SX1276-based border router).
