Is there a way, through powershell, or any other tools to connect and disconnect a paired Bluetooth device? Basically press the Connect/Disconnect button in Bluetooth & other devices, except from command line of whatever sort (Powershell, bat using some command line tools, code in C#, C++, etc.):
I found this answer but it involves unpairing and pairing again, which won't work because my headphones need to be in pairing mode to accept new pairing. I'd rather not simulate keypresses and mouse clicks via AutoIt or some other software like that.

I wrote C++ code to do it using Win32 Bluetooth API's
BluetoothSetServiceState
, but it's actually enough to use Bluetooth Command Line Tools.As it turns out, once all services in use by a device get disabled, device gets released and disconnected by Windows automatically. In my case these are voice and music, as per the screenshot, and most headphones will work the same way.
Voice is actually the hands free service (HFP) and music is just an audio sink (A2DP). Service identifiers will be necessary and they can be discovered through the usage of
btdiscovery
command from the package above, or via the list of Bluetooth services. HFP voice is111e
, A2DP music is110b
.Per
btcom
command line help:To disconnect the device, issue the following (only works when run as administrator in my case, using Windows 10 1809 (17763.437)):
To connect again, issue the same with
-c
instead of-r
. This works for other devices, not just headphones, as long as all services/profiles connected to by Windows get disabled/enabled.Note: using
-n <friendly name>
is much slower than using-b <address>
due to performing Bluetooth discovery.
