nRF9160 FOTA automatic reset

[jwhite]

Hi,

I have a question on nRF9160 FOTA / MCUboot:

I set up an Amazon S3 bucket, and have gotten the http_application_update sample to download application firmware from the bucket. After a device reset, the updated application firmware runs as expected. But I cannot find an option to have this device reset to occur automatically. I will be deploying updates to devices that will not be easily accessible to users after initial deployment, so I'd like this to happen without user interaction.

Before I go further in development, I'd like to know if there's an MCUboot setting, or watchdog setting that I could use to make this happen. I didn't see anything similar to what I'm thinking in the Project Configuration options, or MCUboot documentation.

Best regards,

Jacob

Hi, 

You can have a look at the aws_fota sample : https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/aws_fota/README.html

In the code, they have the sys_reboot(0) function after the FOTA is done which automatically resets the device after the firmware is downloaded.

Hi,

You're right that the AWS fota sample has that automatic reboot in their FOTA handler. I found that the http application update sample has a similar handler function, where I was easily able to add a reset after a FOTA_DOWNLOAD_EVT_FINISHED event flag is thrown. The automatic reset is working as expected. Thanks for your reply!

Hi,

I want to implement a similar process - could you tell me what was the handler function you used for the auto reset functionality? I am looking for the same and I have tried using dfu_target_done() function but it doesn't work for me. 

Thanks!
