nrf Cloud FOTA fail with error code 40000

Question

Hi

I have a issue, I have 4 samples nrf9160 module, all run in same firmware with FOTA feature

I found that only one module cannot start FOTA, then I try to read message from UART0 and got below messages:

00:00:07.627,532] [0m<inf> location: Modem FW Ver: mfw_nrf9160_1.3.6[0m

[00:00:23.163,238] [0m<inf> location_sample: Rebooting in 30s...[0m

I sure that the UUID and Group correctly assigned in nrf Cloud, SDK in 2.5.0, any idea on it?

Best Regards

The settings module is used to save the info of active FOTA jobs so the status can be reported to the cloud when complete. If you enable CONFIG_NRF_CLOUD_LOG_LEVEL_DBG you should be able to see the job execution id that the device has saved. I'm not sure how you your device got into this state... but to fix it, you could reset the settings area that stores the FOTA job information. struct nrf_cloud_settings_fota_job job_inf; job_inf.validate = NRF_CLOUD_FOTA_VALIDATE_NONE; job_inf.type = NRF_CLOUD_FOTA_TYPE__INVALID; job_inf.bl_flags = NRF_CLOUD_FOTA_BL_STATUS_CLEAR; memset(job_inf.id, 0, NRF_CLOUD_FOTA_JOB_ID_SIZE); nrf_cloud_fota_settings_save(&job_inf);
