[LoRaWAN_End_Node_LBM] Process join accept failed with code = 14

[lcordier]

I’m trying to make the example LoRaWAN_End_Node_LBM] work on my nucleo-wl55jc1.

For now i’ve just changed the DevEUI and AppKey in se-identity.h to match my chirpstack configuration.

I can see the join request from my object and the join accept answer of the server but here is what i see on the log of the nucleo:

This error code 14 seem to be related to the secure element but i don’t really understand how to solve it and even what it means.

 

Do you have any idea?
