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.):

Bluetooth & other devices

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.

    LOL, my exact problem. The sony headset handling multi device usecase too poorly and windows having cluncy interface for connect/disconnect.

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 is 111e, A2DP music is 110b.

Per btcom command line help:

Usage:

btcom {-c|-r} {-bBluetoothAddress | -nFriendlyName} [-s{sp|dun|GUID|UUID}]

 -c  Create association between COM port and a remote service (Enable non-COM service).
 -r  Remove association between COM port and a remote service (Disable non-COM service).
 -s  Remote service to use (Default is Serial Port Service)
 -b  Bluetooth address of remote device in (XX:XX:XX:XX:XX:XX) format. 
 -n  Friendly name of remote device.

To disconnect the device, issue the following (only works when run as administrator in my case, using Windows 10 1809 (17763.437)):

"C:\Program Files (x86)\Bluetooth Command Line Tools\bin\btcom" -n "WH-1000XM3" -r -s111e
"C:\Program Files (x86)\Bluetooth Command Line Tools\bin\btcom" -n "WH-1000XM3" -r -s110b

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.

In case the solution from @MarcinJ with Bluetooth Command Line Tools is too slow for you, especially in case you want to pair the device meanwhile an incoming call try creating a windows shortcut:
(Right click > New > Shortcut)

%windir%\explorer.exe ms-settings-connectabledevices:devicediscovery

It will pop up a display and audio panel right on the screen, which is one click away from connect.
And nice BT icon for the shortcut can be found for example on C:\Windows\System32\fsquirt.exe.

    For Win11, this and Win-K only bring up the "Cast Display" side-menu, unfortunately, no longer does this include bluetooth devices. Instead explorer.exe ms-settings:bluetooth brings up the correct bluetooth-connection window.

win 10 shortcuts https://www.windowscentral.com/best-windows-10-keyboard-shortcuts

win-key + K opens the sidebar menu and instantly searches for bluetooth devices. then click on your already paired device and connect.

Maybe Get-PnPDevice, Disable-PnPDevice and Enable-PnPDevice will do the trick for you. I havent been able to test it out though.

Example:

$DeviceName = "YourDevice"
$BTDevice =  Get-PnpDevice | Where-Object {$_.FriendlyName -eq $DeviceName -and $_.class -eq "Bluetooth"} 

Disable-PnpDevice -InstanceId $BTDevice.DeviceID -Confirm:$false

Enable-PnpDevice -InstanceId $BTDevice.DeviceID -Confirm:$false

Change the $DeviceName variable to the name of your BT device.

Get-PnPDevice Enable-PnPDevice Disable-PnPDevice

  • It doesn't, I've stumbled upon Disable-PnPDevice myself too. Depending on what gets disabled (as there are multiple devices, depending on BT profiles), either nothing happens, bt stack crashes or audio output gets disabled but the device stays connected.

  • coolness. Glad you worked it out. I was still digging at this myself. I don't much mess with device in this manner. So, interesting little digging event.

Edited based on OP response.

Looking at the underlying class, that item is not exposed for programmatic access.

Bluetooth​Device.​Close Method

When will Close/Disconnect be implemented? [Windows.Devices.Bluetooth.BluetoothDevice]

When will Close/Disconnect be implemented? Are you planning to have a disconnect? Dispose() doesn't close the connection

There does not appear to be another API doc to say otherwise. So, it looks like you are stuck with SendKeys, AutoIT, etc., at least for now.

  • What I meant by "baiscally press the connect/disconnect button" is perform the same thing Windows performs when that button is pressed, except from whatever code, e.g. PowerShell, bat, C#, C++, whatever. Turning off the whole BT radio won't work, there could be other devices connected, I just want to connect to or disconnect from a specific BT device (headphones).

I have tested the below vbs script successfully in Windows 10. Here I am simulating the keystrokes using the SendKeys command. The number of {TAB}s will be different on your system to reach the bluetooth device name.

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run "ms-settings:bluetooth"
WScript.Sleep 2500 
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{ENTER}"
WScript.Sleep 500 ' 
WshShell.SendKeys "{TAB}"
WScript.Sleep 500 ' 
WshShell.SendKeys "{ENTER}"
