Connecting/Disconnecting to Bluetooth Device via CMD, PS, or AHK?

I had this same problem and it looks like there's already a shortcut for it:

Win + A then click Connect

However, one could abbreviate it further by creating a tricky AutoHotkey script to make it all happen with one keystroke.

#SingleInstance, force
CoordMode, Mouse, Screen


^!c:: ; Press Ctrl + Alt + C to start

; You'll need to find your Connect button's Screen coordinates with Window Spy. 
connectButtonX = 1120
connectButtonY = 570

; You'll need to find your device entry's Screen coordinates with Window Spy.
deviceEntryX = 1130
deviceEntryY = 240

Send #a ;Win + A

WinWaitActive, ahk_exe Shellexperiencehost.exe,, 5
If ErrorLevel
 Return
Sleep, 500
Click %connectButtonX%, %connectButtonY%

WinWaitActive, ahk_exe Shellexperiencehost.exe,, 5
If ErrorLevel
 Return
Sleep, 1200
Click %deviceEntryX%, %deviceEntryY%

Send {Escape}

Try this one: (You'll need Administrative Privilege)

$device = Get-PnpDevice | Where-Object {$_.Class -eq "Bluetooth" -and $_.FriendlyName -eq "FriendlyDeviceName"}
Disable-PnpDevice -InstanceId $device.InstanceId -Confirm:$false
Start-Sleep -Seconds 10
Enable-PnpDevice -InstanceId >$device.InstanceId -Confirm:$false

NOTE: THIS SCRIPT ISN'T MINE, I TOOK IT FROM HERE.
