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 recently run an automatic Windows update (update for Windows 10 version 1803 for x64-based Systems (KB4023057)) after which my Bluetooth has stopped functioning. I have tried the solutions suggested in previous discussions to no avail:

    -- No Bluetooth listed on Network and Internet settings menu

    -- Troubleshooter says "Device does not have Bluetooth"

    -- Bluetooth and other devices menu visible, but no button to turn on Bluetooth; a message saying "Bluetooth is turned off" under every saved device

    -- Driver update clients won't find Bluetooth-related drivers to update

    -- Bluetooth Support Service enabled and running

    -- Drivers listed in the Bluetooth folder in Device Manager: Device Identification Service; Microsoft Bluetooth Enumerator; Microsoft Bluetooth LE Enumerator; Qualcomm Atheros AR3012 Bluetooth 4.0. All appear as up-to-date when searching for updates. No Generic Bluetooth Adapter in sight.

    I had a similar issue. The following steps fixed it for me : 

    Go to Device Manager->Bluetooth->Qualcomm Atheros AR3012 4.0. Right click on it and select update driver. In the following window, select "Browse my computer for driver software". In the next window select, "Let me pick from a list of available drivers on my computer". Here it should show you a "Qualcomm Atheros QCA61x4 Bluetooth 4.1" driver. Select that and press next. That should fix it. If you don't have that driver listed, you may need to download it from Qualcomm / MSI website

    Unfortunately, there isn't way to know the previous version unless you can recall it from memory.
