This application communicates with a LoRa device based on STM32WL chipset. A ST25DV64KC NFC Tag is used to communicate with the LoRa device, to register it on a LoRaWAN network (The Things Network) and to provision it with some keys.
The LoRa device will then be able to contact a LoRa Gateway and start an Over The Air Activation (OTAA). Once this activation done, the LoRa device can send some data to the network.
