buttonless app jlink dfu

I try create my own app based on buttonless app. I've tested dfu over the air it's ok. But for that I need to firmware bootloader (with security key) before. It's ok for production, but while I work on my app I need to firmware chip very many times and of course do it through jlink debugger much more convenient. With previous SDK versions I could do it, I just didn't load the bootloader into chip and it's ok, now I got error in log "no bootloader", if I load BL I can't load my app via Jlink. What's the best way of doing my thing?

  • Thanks. I did the same way in prior sdk (12,13) and it's worked. Actually I thought we must to do it in any case (I mean merge settings app and bootloader hex file).

    But buttonless_dfu app in sdk 14 it's not work. I can programm device without changing after ota, but if I change code a little and try to programm, bootloader not start app and in nrf connect app I see DfuTarg.
