We've got two B-L072Z-LRWAN1 LoRa Discovery kit boards and we're trying to use the end_node demo project, included in the I-CUBE-LRWAN package, to communicate with the LoRaWAN server through a gateway.
In the initialisation phase, it calls the BoardGetUniqueId function to read the DevEUI for the LoRa module. The DevEUI should be unique for each different board. Unfortunately, the BoardGetUniqueId function always returns the same value, but you can't connect two modules with the same DevEUI to LoRaWAN.
I don't find any source code for the BoardGetUniqueId function.
Does someone know how to integrate two or more modules in a LoRaWAN application?
