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.*

    You don't even read my problem. You just read the title and pasted your template about bluetooth issues. If you had read my problem, you would have known that I've already tried those steps over and over again. I'll give you low rating again because of your bad manner.

    Here is the complete process:

    Download the Atheros driver package from https://www.ath-drivers.eu/download-driver-nr-352-for-atheros-AR3012-and-Windows10.html.

    Run the install program.

    Load Device Manager, click Bluetooth, double click the Qualcomm Atheros adapter. 

    Select the Driver tab, click "Update Driver" button.

    Choose "Browse my computer", and navigate to the C:\Program Files (x86)\Bluetooth Package folder.

    Select "Let me pick from....." and then choose the driver you want (10.0.1.11 worked for me).

    I gave you dozens of steps that would take several hours to complete. You reported back in 20 minutes that nothing worked and then gave me a bad rating before you could have possibly completed all the steps.

    Please do not skip any steps. We often find out later that the fix was the skipped step. If you need help performing any step I will help.
