DevNonce is too small

[laesser]

Hello,

I'm using the Nucleo-WL55CJ kit to test the Lora connectivity with TTN server.

At first, all worked fine and I received my data, but now the kit is unable to join the networt with the following error "DevNonce is too small".

Any idea?

Thanks.

Hello @laesser and welcome to the ST Community :smiling_face_with_smiling_eyes:.

The error message "DevNonce is too small" happens when using LoRaWAN MAC version 1.0.4 or 1.1, it's recommended to use LoRaWAN MAC version 1.0.2 or 1.0.1 (version 1.0.3 or lower) for your device.
