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.*

    Hi Greg,

    Thanks for the prompt and comprehensive answer.  

    I have looked into all the options and tried most of them, below are my observations:

    • Going back to system restore would be very difficult as I don't actually know when the problem started. It might have been 3 years ago when I updated my pc with Windows 10 or might have been later. Restoring the system to all those points would be very tedious
    • I have tried updating the drivers from both PC maker and BT adapter's support pages but that doesn't seem to have solved the issue
    • I have tried a few of the links posted above and most of them described updating the drivers and rebooting the system which I have did multiple times

    It seems the issue is related to "Bluetooth User Support Service_5679c" not starting up (or shutting down immediately after starting up). Is there any other way to fix this? Also, regarding point (8) above, how do I know if BT adapter has failed or it's a hardware issue?

    Thanks,

    Darshan

    Hi,

    The currently installed version of Qualcomm Atheros driver on your system is 10.0.1.7 so I suggest you download the latest version 10.0.1.11 for windows 10 from the below link and install it to fix the issue.

    https://www.catalog.update.microsoft.com/Search...

    Let me know the status after performing the above.

    My issue is that Bluetooth appears in the control panel (as I can seemingly turn it on and off) but Windows simply doesn't recognize Bluetooth devices... I can't pair my phone, Nintendo Joy-Cons, etc

    I had the 10.0.2.11 driver and Windows Update didn't detect a newer driver. Updated to 10.0.3.22 and I experience the same issue :C

    This is how it appears on the Device Manager:
