Ah, somehow missed that function myself. That seems to be exactly what I need! Thank you!

RE: Run a function after successful DFU

Hi koos, assuming that you're using the bootloader from our SDK, then the nRF52 will perform a soft-reset after a successful DFU, see on_dfu_complete() in dfu_req_handling.c.

My suggestion would be to write a specific value to the GPREGRET register just before the NVIC_SystemReset() call. Upon entering the bootloader or later the application(depending on where you're advertising that the device is ready for DFU) you can check the value of this register. If the register matches the value that indicates that a successful DFU was completed and you're charging, then you stop advertising.

Best regards
