NUCLEO-WL55JC1: LoRaWAN_End_Node_LBM Join Accept Failed with Code 14 (ChirpStack)

[gsmith84099]

Hello ST Community,

I am attempting to run the LoRaWAN_End_Node_LBM example project from the STM32CubeWL MCU Firmware Package on a NUCLEO-WL55JC1 board, connecting to a ChirpStack LoRaWAN Network Server.

While ChirpStack shows both the Join Request and Join Accept frames, the node fails to join and loops endlessly in a join retry state.
Configuration & Keys

    Updated AppEUI in se-identity.h to match ChirpStack settings.

    Tested on STM32CubeWL Firmware Package V1.6.0 (and verified same issue on V1.5.0).

Environment / Software Versions

    Application: LoRaWAN_End_Node_LBM (V1.6.0)

    Middleware (MW) LoRaWAN: V1.1.0

    Middleware (MW) Radio: V1.4.0

    L2 Spec: V1.0.4

    RP Spec: V2-1.0.4

Event received: JOINFAIL

Has anyone encountered Process join accept failed with code = 14 with the LBM stack? Any insights into what error code 14 indicates or suggestions on resolving this would be greatly appreciated.

Hello ​@gsmith84099 ,

This error code is related to a mismatch on security material between the End-Device and the ChirpStack configuration.

We noticed you changed the AppEUI without specifying the value set.

Could you please share the configuration of JoinEUI ?
