Can I program nrf52 with bootloader and application image?

[Newbie]

Hello, I am using nrf52 and sdk12.2.2. Can I program this with bootloader and application image at once using nrf go studio? At present I am first uploading bootloader image after that I am uploading application zip file via OTA. But I want to upload bootloader and application file using nrf go studio for production purpose. Thanks, Shailav

Download nRF Command Line Tools which include a tool called mergehex.

You can use this tool to merge any number of hex files (assuming they don't have overlapping addresses).

mergehex -m application.hex bootloader.hex softdevice.hex -o merged.hex

Next you can use nRF Go to flash the merged hex file, or you can use the command line tool nrfjprog which is included in the aforementioned package.

Hi Shibshab, Where is the option to program merged hex file in nrf go studio? I tried to program nrf52 using command line tool. nrfjprog -f NRF52 --program ..\all.hex My all.hex files includes 3 files

1. Softdevice.hex 2)Bootloader.hex 3)Application.hex Now when I am programming my nrf52 with my all.hex file my nrf52 advertises only with "dfutarg". I want my my nrf52 should advertise with my application image. Thanks, Shailav
