Thanks! It seems like the 4th time was the charm.

After my first 2 iterations, I concluded that prj.conf was probably the preferred file. No idea why it didn't work when I tried it those first 2 times. And when I tried it a third time (even redownloading the files from github) it still didn't work.

Maybe your comment about "not flashing the board properly" is the only reasonable explanation? This 4th time I used Erase And Flash To Board (instead of just Flash) and now it works. Not sure why that would have been required since I don't recall ever using that approach before. But thanks for the suggestion!

Hi Doctiplus.

Thanks for posting this, I'm in a similar boat (mostly HW, just diving into the SW side with the nRF SDK). From what I understand, you should pick one .conf file, typically prj.conf for the full feature set unless the lesson specifically asks for the minimal version. Using both can definitely cause conflicts.

Also, make sure you've selected the correct build configuration in your IDE (e.g., in VS Code with the nRF extension). I had a similar issue, and it turned out I was building, but not flashing the board properly. Double-check your flash/debug settings too.

Let us know if you get it working, I'm curious how it turns out!
