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.*

    I have this problem with Windows 1909 using an Asus X99 Deluxe motherboard.  None of my Bluetooth devices will connect like they did before even after a fresh install from 1909 download media.  Some devices appear in the Bluetooth wizard but they never successfully pair.  Other devices never even show up.  This is 1909 Build 18363.535 as of 1/2/2020.  The Bluetooth troubleshooter always identifies a problem the "radio status" and then marks it as "fixed" but the result is always the same as before (and the troubleshooter claims to fix the issue repeatedly).

    I am NOT impressed by Windows build quality.  I will try an external Bluetooth antenna/nano adapter, but seriously, ****?

    same with me .

    whenever there is Bluetooth problem people start suggesting BT services, troubleshoot, recovery etc before even listening. I have also tried all above mentioned problems and still couldn't resolve the issue. only thing remained is reinstalling windows which I don't want to and yes I have tried different adapters different ports also
