How to perform OTA DFU of NRF52840 from NRF DFU or NRF Connect Device Manager app

[JGusler]

Title says most of it. I'm wanting to perform an OTA DFU of an nRF52840 running NCS 2.0.0 using my android from either the nRF Connect Device Manager or nRF DFU app. There are so many disparate guides that aren't clear or are out of date so I'm just completely lost.

Check out the guide  Add DFU support to your application It was made for NCS v1.8.0, and I'm pretty sure it should work with NCS v2.0.0 as well. Try following the steps in the guide with NCS v2.0.0 and let me know if you encounter any issues.

Best regards,

Make sure you have added the following to the prj.conf file. Then include img_mgmt.h and os_mgmt.h and build the project. It doesn't really matter what VS Code says, the important thing is that you don't get any errors from the compiler/build output.

Let me know if you get an error from the compiler/build output after doing the above.

Also, let me know if VS Code still complains after doing the above. It might a bug with some of the extensions.

Everything builds happily for my combination of that sample into my current application but now when I try to view RTT output I get absolutely nothing. MCUboot is generating all the files I expected, and mergex.hex is being flashing to the chip.
