Bluetooth Issues Since Surface Updates - 5 August 2021

Checking in to report that sadly, changing to a generic Bluetooth driver did not work for long either. It's still showing as a Generic Bluetooth Adapter in my Device Manager, but when I check its properties, it also says "No drivers are installed for this device".

This continues to be a huge problem. Hopefully, Microsoft understands this. It's unfortunate that no one from Microsoft has responded since your initial post 3 days ago as I've no doubt there must be multiple reports of this issue beyond this thread😕

I'm having the exact same issue, When I run the troubleshooter I get the error:

Check Bluetooth Radio Status

Marvell AVASTAR radio adapter has a driver problem.

I really hope we get a resolution to this soon!

I've tried rolling back the driver, uninstalling the driver, checking for updates from Microsoft.

Bluetooth works for about 5 minutes, then the icon completely disappears.

Running the troubleshooter worked the first time. It said restarting radio adapter.

Then after each subsequent times I got the above errors.

Many thanks Brenda and others for their contributions. Very oddly, since turning my Surface on this morning, Bluetooth (BT) has been working for the last 4.5 hours, but, of course, it may fail again at any moment! I think that those with continuing problems, should also put some feedback on the Feedback Hub.

It may be a longshot, but I suspected that the Your Phone' app may have been interfering with BT since the firmware update. Late yesterday, I had an unusual in-app update notification in the 'Your Phone', which I actioned. I say unusual because Your Phone app updates usually come via the Store and this didn't. So, I'm wondering if anyone else is using the Your Phone app and whether actioning the in-app update has changed the BT issue for you.

I have the same problem on my surface 6, latest win 10 Version with the Marvell AVASTAR Bluetooth Radio Adapter. After a reboot all BT devices are working properliy and then all connections are lost, the BT symbol is gone as well a s the switch. The driverversion is 15.68.17021.121

I looked up the event manager and found an error with

ID 411:

I tried all the basic stuff like reinstalling the device driver, de- and activating the device, rebooting, installing from the surface firmware package. Nothing seems to fix this permanently.

I got the same problem on my desktop pc. after in removed the update KB5003537 (which was not on my surface) bluetooth seems to be stable after hours of music streaming.

I'd really appreciate a fix from the annoying connection breakdowns since my surface is my machine to work with :)

In my last post, I said that I thought that using the 'Your Phone' may be related to our Bluetooth issue. Since my last post, the Bluetooth had been working fine. I noticed, however, that I was not able to make calls on the 'Your Phone' app app, so, following the Help advice, I re-paired my Android device which then enable Calls to work, but then the Bluetooth issue came back. So, perhaps there is a link. I would like to hear if anyone else experiencing the Bluetooth issue has been using or not using the Your Phone app please?
