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 did try to follow this procedure but it does not the cab file as Microsoft generally search for .inf files when upgrading drivers. Do let me know how you passed the .cab file

Extract the .cab file in a folder, there you will find the -inf file that the driver update utility needs to read when you are asked to prompt for it.

HI, I need help with my bluetooth in windows 10.

PC: MSI GS60 2QE , bluetooth Qualcomm Atheros AR3012 4.0 , driver 10.0.1.14

I did all the things i could find online, troubleshooter from windows page, update driver, uninstall, etc..

My problem is this:

Computer shows all ok, bluetooth with no issues, working properly, but i cannot add any device (nothing found) and also PC not visible to any device (i tried to find it with phones or bluetooth headsets)

Before update to win 10 all worked ok, no bluetooth since then.

What else should i try?

Rgds

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
