I have an AX210 Bluetooth card. Ever since clean installing Windows 11 21H2 I have the following 2 issues with every Windows 11 supported Intel Bluetooth driver. Windows 10 did not have those issues at all
I have two 8bitdo controllers which both sometimes show a Driver error when the controllers are paired (but not connected). This can be provoked when turning Bluetooth off and then on again. Many people are having this issue (with other Bluetooth cards) with Windows 11 as can be shown in the following links
When trying to connect the controllers, they appear to connect fine but there is no input registration. You can find a video with steps for the issue here
Deleting and reparing the devices as well as deleting and reinstalling the Bluetooth driver and running the Troubleshooter several times only fixes this temporarily
I have tried contacting 8bitdo but they can not reproduce the issue.
When such a problematic BT device as above is paired, the Bluetooth button in Quick Settings (appears when left-clicking on the right lower sound and network icons) sometimes hangs when trying to turn Bluetooth OFF and Bluetooth takes a very long while until it is disabled. You can find a video with steps for the issue here
Two others with different Bluetooth cards have the same issue in the following thread (please scroll further down in the link).
Note that one of them is having this issue caused by a Bluetooth Audio device and not a controller.
What I have tried
- Deleting and reparing the devices as well as deleting and reinstalling the Bluetooth driver and running the Troubleshooter several times only fixes this temporarily
- Swapping my AX210 with a WIE7265 Bluetooth card did not fix this
- SFC /scannow did not find any errors
- Trying different Intel Windows 11 supported Bluetooth drivers
I can not use my Bluetooth controllers nor disable Bluetooth properly because of these issues.
