Windows 10 Bluetooth device won’t connect after windows reset

bluetoothsystem-restorewindows 10

So, after two years with a single windows installation it began to give me some troubles, so I thought it might be time to reset is back clean install. On this installation I had my Sony WH-1000MX2 working perfectly.

After the wipe and installing all my software again, I thought OK, just the headphones and i'm done. That's where the problems begin.

I set the headset in pairing mode, go though the standard Bluetooth paring. It finds it, connects to it. Says connected for like 5 seconds and go's in to "Paired" when manually connecting it will just say "That didn't work. Make sure your Bluetooth device is still discoverable, then try again".

I have removed it from the list, and turning on/off Bluetooth it sometimes show back up again, so I used registry editor to remove the Device from
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Devices

I have uninstalled the Bluetooth module from Device management, I have tried to uninstall the driver from device manager. I can't seem to find anything strange in the Windows event log.

After about 2 days of trying, no success.

I know it might be strange, but it feels like the windows reset kept the connection to the headphones and the old security code used to connect to it some where, but I can't seem to make windows forget it. When i connect an different Bluetooth dongle, it works almost instantly, so am i missing some registry entry somewhere to make it work with the internal module again?

Best Answer

had a similar issue to this, finally managed to sort it out.

My symptoms:

  • Previously working bluetooth speaker (UE BOOM 2 in my case) stops connecting
  • Windows 10 'Bluetooth and other devices' menu shows the device as Paired
  • Pressing connect makes it attempt to connect but fails then it goes back to Paired
  • Remove device hides the device from the menu, but as soon as you turn bluetooth on and off, or restart the computer, the device comes back
  • You pull your hair out.

Solution that worked for me after much, much unsuccessful internet trawling and one system restore:

  • Download this 7 year old command line bluetooth toolset: http://bluetoothinstaller.com/bluetooth-command-line-tools/
  • Install it, make sure you enable the option to "Add Bluetooth Command Line Tools directory to path"
  • Open Powershell
  • Put your device that isn't working properly into pairing mode

WARNING: THE FOLLOWING COMMAND WILL UNPAIR ALL BLUETOOTH DEVICES

  • type in "btpair -u"
  • Boom, all of a sudden Windows asks me if I want to allow pairing to my device that isn't working
  • Hit yes, successfully connected again
  • Cry tears of joy

Hope this helps.
