Hi Lurnz,

We unfortunately don't have an official sample for that.

Enable NRF_BL_DFU_ALLOW_UPDATE_FROM_APP is the right configuration but you need the code in the app to receive image and write some meta data correctly for the bootloader to boot and swap the image. We have a sample made long ago but could be a good place to start. Please take a look at this ticket, Vidar has provided a sample for background DFU here:
