RAK7431 goes offline itself

Why is our RAK7431 device going offline itself? It goes offline irrespective of ADR and Join modes. There is no issue with the power connection to the device and the LoraWAN gateway.


I am having same problem ! after 40-50 min node goes offline or what I don’t know , but join request is not accepted by NS, also CLASS C changes From CLASS A.

Do you have any idea …???
