A while ago, I started up the Robot Inventor program and noticed the computer was not connecting. When I clicked the "Connect" button, the loading "circle" simply started spinning either indefinitely or for a few seconds until the "Connect" button showed up again. The Bluetooth on my Dell E5540 is on, and the 2 devices are paired.

  • Did you try pairing the hub using the Windows Bluetooth settings first? Apr 24, 2021 at 0:43

Maybe this project legoBTLE4pi could help you. It connects a Raspberry PI via Bluetooth to a Lego Powered Up Brick and does all the funny stuff.

The project is ongoing (nice TUI etc) but everything works.

    I'm not sure how a Raspberry Pi-based project could help the problem OP is facing with their computer - could you please elaborate on this aspect?

  • I thought maybe by using a vm with Linux this problem could be circumvented. However, you're absolutely right, I answered quicker than I thought. Please excuse this lapse. May 6, 2021 at 17:03
