RE: in the SDK 15.3,How to directly execute the application when the DFU function is added。MCU：nrF52832

Ming

hi,

        in the SDK15.3，I successfully ported the DFU demo to app_uart, but the 52830 will enter the upgrade state each time after downloading the program. I want to know how to solve this problem? I have tried adding bootloader setting, I am sorry that this problem has not been improved.

      And I tried the following method:

     @echo Flashing Softdevice and bootloader
     mergehex -m $(OUTPUT_DIRECTORY)/nrf52832_xxaa_s132.hex $(SDK_ROOT)/components/softdevice/s132/hex/s132_nrf52_6.1.1_softdevice.hex -o sdbl.hex
      nrfjprog  -F - nrf52 --program sdbl.hex --chiperase -r.

       thanks.

    Can you show how you're generating and programming the settings page?

    of course,I learned from this blog，and I am doing this too.

           When I downloaded all the hex (soft device, bootloader, application.hex) files, the device started broadcasting "DFUTarg".And I tried to update through DFU, it succeeded.

    Then,

    nrfutil settings generate --family NRF52 --application myapp.hex --application-version 0 --bootloader-version 0 --bl-settings-version 1 bootloader_setting.hex
    After generating boot seting, I use nrf connect to download both softdevcie, boot, boot setting and app.When I found that there was no change, I combined the bootloader and setting into a file.But the result is the same after downloading.

           These are the logs that the NRF connect prints when programming

    Thank you. I see you've set the "--bootloader-settins-version" '1'. It should be '2' since you use SDK 15.3.0. Can you try to change it and see if it helps?

    Thank you,but It doesn't seem to change anything.

    Hi,

    Can you upload the .hex files you use so I can try it here? I can make the ticket private if you want.
