Bluetooth Issues Since Surface Updates - 5 August 2021

The Bluetooth on my Surface Pro (5th Gen) has not been working properly since the Surface Firmware Updates this morning. I have to restart to get it to work and then it only works properly for about 5 minutes. I have tried rolling back and reinstalling the Marvell driver. Also the Bluetooth troubleshooter doesn’t fix it. Running that troubleshooter causes Bluetooth to completely stop working. Will you please fix this urgently as it is a major issue for me?

    Hi MFO. Many thanks for all that you have done to try and diagnose the problem. It's now been 9 days since the issue emerged, so hopefully Microsoft will have seen all of the posts here and elsewhere and will have a fix soon.

    Surface Pro 6, Marvell Bluetooth Driver .121. Same issue - bluetooth began operating erratically after my machine ran updates on the 6th. Bluetooth just stops. I only run a mouse and some bluetooth speakers and never had an issue before the last few days. I opened a case with Microsoft three days ago, they told me to roll back the driver (already did), run the .msi update (already did). I also played with seetting bluetooth audio bridging service to auto, turned off power saving for bluetooth, etc. SO.....Before they could tell me to, I went ahead and did a clean install.

    In order to determine if it was firmware or driver, after the clean install I did not update the Surface Pro 6 with any updates at all by keeping it off the internet. The Marvell driver that ships with the current version of the USB Media Creation Tool for a clean install is 15.68.9112.23 and is dated 12/2/2016. Same mouse and speaker ran for two hours straight, no hiccups or issues. SO... Firmware may not be the issue.

    I disabled the Vendor Driver Auto Install capability thinking Marvell might have slipped in a sketchy driver through this annoying avenue, crossed my fingers, and enabled the internet and let the Updates go. The Marvell .121 driver installed, machine updated completely with mouse and speakers running fine, and rebooted.

    After reboot, mouse and speakers worked fine for 31 minutes, then took a a dump. Same issues. In my mind, anyway, the .121 Marvell Avastar bluetooth driver (which is in the .msi they direct you to as well as in Windows update) is the problem.

    Surface Pro 7 and have the same problem. BT keyboard/mouse is ok but once i connect to a BT speaker or headset i lose my BT connection; time varies but losing BT connection is a given. I've tried everything known to man...

    MSFT needs to come up w/ something. I'm losing my mind.

    I'm on a surface pro 6, same issue. I can get Bluetooth working temporily for a short period and then it stops again. Yesterday at one point the option for turning Bluetooth on and off completely disappeared until I ran the troubleshooter. It's a real pain as I use a Bluetooth keyboard, mouse, headphones etc. DESTROYING MY WORKFLOW.

    I remember a similar issue from over a year ago but that was patched by an update.

    Microsoft, can u please tell us if u are working on a fix?
