CubeWL LoRaWAN End_Node example wont connect to Chirpstack due to Nonce

I'm developing LoRaWan project using that uses STM32WL5MOC module and the STM32CubeWL MCU Package (STM32Cube_FW_WL_V1.3.0). I have B-WL5M-SUBG1 module to develop with.

I am seeing that the End Node example does not connect with Chirpstack due to noncompliant DevNonce.  It seems I need to patch ST’s CubeWL LoRaWAN End_Node example to make DevNonce persistent across power cycles so that ChirpStack will accept joins).

Has anyone else experienced this?  Any insights are welcomed.

Peter

Hello @PLaid.1 

I suggest you to have a look at this article from Digikey. It gives a description on how to connect the STM32WL to the ChirpStack.

Best Regards.
