LoRaWAN_End_Node_FreeRTOS application on Nucleo-WL55JC1. Problem resetting LORAWAN_APP_KEY

[pe]

I'm using STM32Cube_FW_WL_V1.3.0and trying to generate LoRaWAN End Node FreeRTOS. I precedently set in file se-identity.h values for LORAWAN_APP_KEY,LORAWAN, LORAWAN_NWK_KEY,LORAWAN_JOIN_EUI, as shown in the guide and everything went fine.

Now I want to assign them new values in the same manner, but after compiling the project and programming the device with ST-LINK, on boot in the serial output it shows the first ones that I set:

APPLICATION_VERSION: V1.3.0
MW_LORAWAN_VERSION: V2.5.0
MW_RADIO_VERSION: V1.3.0
L2_SPEC_VERSION: V1.0.4
RP_SPEC_VERSION: V2-1.0.1
NVM DATA RESTORED
###### AppKey: F2:54:51:E9:24:11:25:F7:A5:24:80:97:32:CC:58:CD
###### NwkKey: F2:54:51:E9:24:11:25:F7:A5:24:80:97:32:CC:58:CD

...

The output shows that the values was restored from NVM, but I can't manage to change them in NVM.

How can I force the new values into NVM. Related to this, how does the BUT3_Pin work? It activates thread Thd_LoraStoreContext ( that calls the func LmHandlerNvmDataStore)  but seems it not store the new values

Can anyone show me how do or what is the problem?

thanks

Hello @pe 

Thank you for your request. I've escalated this use case to the concerned team for more investigation (through Internal ticket number: 175276)

(PS: Internal ticket number 175276 is only for reference, not available outside of ST).

Best Regards.

Hello, you just need to change line 100 in the lora_app.h file to set #define LORAWAN_FORCE_REJOIN_AT_BOOT to true (the default value is false). This will force the device to rejoin. Otherwise, the device will restore data from the non-volatile memory.

thanks.
