RE: SDK 14.2: how to debug application with buttonless DFU

That did the trick, thanks!

For anyone else bumping into this in the future, I added a batch file called by SES after the debug build with

nrfutil.exe settings generate --family NRF52 --bootloader-version 2 --bl-settings-version 1 --application-version 219 --application C:\[path]\App1000.hex --key-file C:\[path]\private.pem C:\[path]\dfusettng.hex

(where [path] is the correct path for my build). Not sure if the private key is required, but having it works fine.

Then in the SES debug loader, I have "additional load file 0" with the name of the combined bootloader and softdevice, and "additional load file 1" is C:\[path]\dfusettng.hex

Use NRFutil to generate the bootloader settings page (or pages for newer bootloader versions, SDK 15+) and then flash this page in addition to your new firmware.
