Hi Team,

I am facing some issues with the LoRaWAN MAC layer version 1.0.4. I have registered and called the store context function, but I am still having trouble switching the end nodes in the TTN server. Additionally, I am receiving a “devNonce is too small” error when trying to connect the same end node a second time. The first attempt works fine, but I encounter this devNonce error on the second attempt ( or )Sometimes ,but My devnonce counter value increments each time I send a join request, but I am still facing this “devnonce is too small” issue. it takes five minutes to connect to the same end node a second time… Is this a security feature or a bug? Please confirm on your side.

i am using STM32WLE5CC controller.
RAk wireless gateway

Thank you.
