dfu in application

[Michal]

Hello

I am wondering if there is example where dfu is implemented within application and bootloader is only coping image from flash bank to application space. My companys product need to be running during OTA which last ~2mins. I know that bootloader offers dual bank so I assume it is possible.

Hi Michal,

we do not currently have an example that implements Background/Trickle DFU. However, we plan to implement this and add it in a future SDK release, but I can not give any guarantees or estimated release date.

I know that there are customers that have made custom implementations, so it is definitly possible, but as far as I know none of these implementations has been shared here on DevZone.

Best regards
