Hi,

You may find useful information in this dongle programming tutorial.

 As stated in this issue, it seems that nrfutil cannot work with Python 3. If nrfutil is not working for you due to not supported python version, you could install virtual environment with python v2.7 and install nrfutil there.

Since you are already using nRF Connect, the easiest way to program your application would be to use nRF Connect Programmer application. After building the application in VS Code, search for hex file (in the folder build\zephyr) and program it to your device using Programmer application.

For Programming nRF52840 dongle, I have followed this steps but none of this works for me. after programming dongle did not come out form DFU mode.

Could you please provide more information about where the errors occur? Can you share what kind of errors you are getting in each of the cases?

Best regards,
Dejan
