BLE pair issue on zigbee demo "light_switch"

[pintai]

Hi,

I'm currently using “light_switch” to enable BLE NUS, but every time the device reboots it needs to be re-paired, I checked the serial logs and found that the pairing information failed to be saved.The SDK is NCS2.8 add-on.Please help to see how I can solve this problem.Tanks.

The error log is as follows:

E: Failed to store CCCs (err -2)
E: Failed to save keys (err -2)
I: Pairing completed: 48:3F:E9:54:EF:AA (public), bonded: 1
E: Failed to store CCCs (err -2)
E: Failed to store Client Features (err -2)

E: failed to store SC (err -2)

E: Failed to store CCCs (err -2)

Hi,

Can you share what the generated partitions look like?

You can generate this with the "Memory report" action in the VS Code extension. Selecting the "partitions" tab in the memory report to see the partitions. You can also use the following command in a terminal:

west build -t partition_manager_report

Best regards,
Marte

Hi

Thanks for your reply.

Hi,

I see you have tagget the ticket with nRF54L15. The nRF54 series use ZMS and not NVS. Can you try changing CONFIG_SETTINGS_NVS=y to CONFIG_ZMS=y?

If you still see issues after this change, can you do a pristine build and upload the build log here? Please copy the full log and share it as text using either Insert > Code or as a .txt file.

Best regards,
Marte
