If after powering up the LoRaWAN FTD, the Join Request (JR) is looped without receiving a Join Accept (JA) from the network, you need to :
- ensure that you have correctly provisioned/declared* the FTD on the network to be qualified (operator backend or gateway),
- check the accuracy of the LoRa keys entered when provisioning the FTD,
- make sure you are under network coverage (consult the operator sites on network coverage if public network operated or test near the Gateway if private network operated).
* To know how to declare a product on an operator backend refer to the corresponding question in the "First steps with a sensor" section of the FAQ.
