Bluetooth Issues Since Surface Updates - 5 August 2021

Hi GF. Same here. Mine had been working for a day and a half but then started playing up again this afternoon. So, probably, 'Your Phone' is not the culprit, just the victim of a very unstable Bluetooth driver. Between times (last night) I did install the monthly MS updates and was didn't experience the issue after at least two restarts / shutdowns, so you might be lucky.

Hi TrevorFayers, I do not use that app at all for what it's worth. My bluetooth has also been seemingly working again, although I keep waiting for it to stop and I didn't use my computer at all yesterday (was reluctant to spend a third day raging at it lol). Today it's so far so good. I did notice that some additional updates installed themselves yesterday while I was away (Intelligence update for Msft defender antivirus as well as Windows Malicious Software Removal Tool). There is also a new cumulative update (2021-08 Cumulative Update for Windows 10 Version 21H1 for x64-based Systems (KB5005033)) waiting to finish being installed (pending restart) and I won't lie, I'm a little nervous to restart since bluetooth is still working right no

.....and I spoke too soon. Bluetooth crapped out again. I believe I managed to use my usual mouse and keyboard all of 30 minutes this time. Now I'm back at the media keyboard. I guess I may as well do the restart and see what happens 🤔

Our customer has exactly the same problem.

We cant roll back to the driver using the ROLL BACK DRIVER and confirm they are suffering the same issue since the update on the 6th August

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?

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 :)
