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

remove AR3012 & its drivers completely from 20H1, later let 20H1 detect it as Generic Bluetooth Radio.
download Qualcomm driver v10.0.1.15 from Microsoft Catalog website, install this driver via driver upgrade.
after v10.0.1.15 being installed, you might see additional device named in "Bluetooth LE" as the one in the Kirill's figure.
try to connect any BT device you couldn't connect after upgrading to 20H1, make sure the AR3012 really WORKS.
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 had the same problem.

Here is what I did to solve the problem:

go to: Device Manager/Bluetooth/"name of the BT adapter (for example: Intel Centrino or Dell Wireless Bluetooth etc.)"

then: right click on this adapter and click "update driver" and next click on "Browse my PC for Driver" and next click on "Let me pick from a list on my PC"

here is the trick: from the list presented choose "GENERIC BLUETOOTH ADAPTER" and click "next"

That make my Windows 10 not only "pair" with my BT Speaker but also CONNECT and PLAY audio in to it;

Good Luck!

I upgraded a laptop from Win 8.1 to Win 10 and had an unknown BT device with hardware ID BTHENUM{cbecab40-a2c8-4ab3-adc1-de0fe95d8600}_LOCALMFG&0000

I noticed online many people struggling with same issue and disappointingly they received the same basic support if no replies at all.

So just download following file and extract the x86 or x64 driver folder, then update the driver manually

http://bit.ly/Win10\_AtherosBT-AR301X\_x86-x64

I tested on a 64bit OS but I guess it should work as well as on 32bit OS, and it may work with other Atheros BT devices of the series AR301X

Good luck

(I would appreciate at least an "Hi, thanks!" as a reply)
