Here is how I made the AR3012 working again on Windows 10 20H1.

  1. remove AR3012 & its drivers completely from 20H1, later let 20H1 detect it as Generic Bluetooth Radio.
  2. download Qualcomm driver v10.0.1.15 from Microsoft Catalog website, install this driver via driver upgrade.
  3. after v10.0.1.15 being installed, you might see additional device named in "Bluetooth LE" as the one in the Kirill's figure.
  4. try to connect any BT device you couldn't connect after upgrading to 20H1, make sure the AR3012 really WORKS.
  5. then download any Qualcomm driver v10.0.3.x (as Kirill mentioned, the newest one is v10.0.3.22, or let Windows Update do it later), upgrade  the driver of AR3012 again with this one.

Notice: NEVER uninstall the v10.0.1.15 while/after upgrading to v10.0.3.x, or the AR3012 will fail again after reboot.

Microsoft Generic Bluetooth Driver -> Qualcomm BT driver v10.0.1.15 -> Qualcomm BT driver v10.0.3.x,

if you did followed the steps, your AR3012 should be working as usual, even after reboot. 

Qualcomm Atheros Communications - Bluetooth - 10.0.1.15 (x64)

Qualcomm Atheros Communications - Bluetooth - 10.0.3.22 (x64)

I guess the "Bluetooth LE" is the critical point of this issue.

(I DID hate the crappy W10...... what's M$ doing now? let users recall how windows unstable in 1990s? )

NOTE by MELERIX: by the way, as it is an older driver, it does not support the new Windows 10 shutdown mode called fast startup*, so every time you shut down Windows and then restart it, the device appears with an error, so you have to* disable the fast startup of Windows 10*, in the power options of the control panel.*

    Thanks for the recommendation,

    From the first command I got the message 'No component store corruption detected'.

    From the second, 'The restore operation completed successfully'.

    The third command: 'The operation completed successfully'.

    And from the 'sfc/scannow' command, I got the message 'Windows Resource Protection

    found corrupt files and successfully repaired them'.

    Unfortunately, this has not helped with Bluetooth. I have also uninstalled and reinstalled my

    Bluetooth drivers, but this has not worked either.

    I have tried opening 'device manager' and updating the three Bluetooth features, firstly

    'Bluetooth Device (RFCOMM Protocol TDI)', secondly 'Microsoft Bluetooth Enumerator' and

    lastly 'Qualcomm Atheros AR3012 Bluetooth 4.0'. This also has not worked.

    My Sony wireless speaker and Skullcandy wireless headphones definitely used to connect

    via Bluetooth to my PC, and I think I started having problems with them around the time

    of the Windows 10 update. When I removed these devices in order to reconnect them, it

    did not work, and still does not.

    Is there anything else anyone can recommend?

    Hi WayneSmith_271,

    I am an Independent Advisor and I would be happy to help you today.

    I recommend using System File Checker tool (SFC) and the Deployment Image Servicing and Management tool (DISM)

    Press the Start > type the word CMD > right click on the command prompt > select Run as administrator

    Enter the following commands one by one followed by the Enter key:

    DISM.exe /Online /Cleanup-image /Scanhealth

    DISM.exe /Online /Cleanup-image /Restorehealth

    DISM.exe /online /cleanup-image /startcomponentcleanup

    sfc /scannow
