Hi @heniugg. Unfortunately, currently only serial ports are supported by Arduino IDE 2.x: Network port support · Issue #123 · arduino/arduino-ide · GitHub This limitation actually comes from the Arduino CLI tool that handles all the non-GUI related tasks for Arduino IDE 2.x. So network discovery must first be added to Arduino CLI. After that, it should quickly be possible to do the same in Arduino IDE 2.x.
That's correct. If you want to monitor the progress on this feature, you can subscribe to that issue: https://github.com/arduino/arduino-ide/issues/123
The issue will be closed once the feature has been added to the IDE.
