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.*

After the windows 10 update, on a Lenovo Idea Pad Z710, my Moto X Gen2 Android phone will pair with my laptop. The laptop shows it is connected to the phone, but the phone won't connect to the laptop. I have updated all my bluetooth drivers. I'm am using Android version 5.1 on the phone. The phone shows in the bluetooth driver area of device manager, and it's drivers are updated. The version of the Atheros driver is 10.0.1.1, with a date of 6/27/15. The phone driver (XT1096) is version 10.0.10240.16391. It seems weird to me that driver from microsoft has a date of 6/21/2006. Running an update tells me it's the best driver....I also tried turning off all firewalls to no avail.... Any suggestions?

I recently upgraded to windows 10 and the bluetooth doesn't work anymore. I usually use bluetooth headphones with my laptop and it did work for a bit after I upgraded and then it just stopped working completely. Any ideas on how to fix this problem and what I should do?

My laptop is a samsung rv515 and I upgraded from windows7
