The Bluetooth worked fine until I run
Disable-NetAdapter * and then
Enable-NetAdapter *. It was supposed to just turn OFF/ON all net adapters (including Bluetooth), but it actually disconnects the Bluetooth hardware (I guess it's a bug).

Is there a PowerShell command to reset the Bluetooth hardware connection to the computer, and then try to detect it again?
