After Windows 10 2004 update Bluetooth devices disconnect and reconnect randomly

L

Good evening,

Since the Windows 10 2004 update all my Bluetooth devices frequently disconnect and then in a minute or two reconnect.

Bluetooth devices that disconnect / reconnect include but are not limited to:
a) 2 different Microsoft Bluetooth mice.
b) 2 different Rocketfish Bluetooth keyboards.
c) 8 different Bluetooth headsets.


When reviewing the Event Logs, I found 100s of BTHUSB Event ID: 34 and HidBth Event ID: 2 entries.

The reconnects line up with the HidBth Event ID: 2 Warning entries


The Bluetooth radio in my computers is a combo Intel Wireless Bluetooth and Intel Dual Band Wireless-AC3160.

Computer: HP Envy 17

Windows Version: 10.0.19041 Build 19041


Last Update: 2020-09 (KB4571756) Cumulative Update for Windows 10 Version 2004 for x64-based Systems

I've gone through every entry in the Bluetooth, Network, Mouse, Keyboard, and Human Interface Devices sections in the Device Manager and disabled the 'Allow the computer to turn off this device to save power" anywhere and everywhere I found a Power Managment tab.

I've uninstalled and reinstalled the Intel drivers for both the Intel Wireless Bluetooth and Intel Dual Band Wireless-AC3160 devices.

I've rebooted my computer many times after all of the above.

The problem only started with the application of the Windows 2004 Update.

Any help greatly appreciated.
