Saving and Retrieving Fatal Error Logs on nRF9151 After Watchdog Reset

Good afternoon,

We are using an nRF9151 device to send data over LTE-M. Our gateway, located in Sweden, occasionally resets unexpectedly. We suspect that a fatal error is triggering the Watchdog timer, causing the reset.

Question: Is it possible to save the details of a fatal error to the device’s flash memory before the reset occurs? After the device reboots, we would like to retrieve and send this error log via MQTT. This would help us diagnose the issue remotely when the device is deployed in the field.
