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.*

ASUS X555UB Laptop has a AR3012 Bluetooth device with all the default drivers installed.

Problem is that all the bluetooth connections pair immediately and then fail to connect with the following error displayed instantly as if it didn't even try: "that didn't work make sure your bluetooth device is still discoverable"

I have made peace with all other devices not connecting but really need the headset to connect.

The problem is not with the headset as it works on other windows editions. I've not been able to connect since build 1709... now on build 1903. Prior to that it all worked fine

Latest driver applied from Windows Update Catalog is 10.0.3.19

I've tried everything including logging support call with ASUS support who simply refer to the latest driver

Hello everybody:

I have a problem with Bluetooth, and have already tried all the basic solutions. The problem is, when Windows start, Bluetooth starts too and it even connects to the speakers if they're on, but for instance I can't see the icon in the bar below. Also, when I open the device manager, I get this picture:

The Bluetooth icon displays a list of all the Bluetooth devices installed, and everything is OK, but below that, where it says other devices, you can see there are some with a question mark or the yellow triangle.

I suppose there was a problem during the installation of the driver and so I'd like to know what to do in order to uninstall and reinstall the service completely. I tried uninstalling the drivers from the device manager, but after I reboot the computer they are installed again.

The adapter I have is Atheros AR3012, I'm running Windows 10 Pro, and like I said, I've already tried all the basics. Honestly I don't want to waste any more time with possible solutions, I'd prefer a clean start.

Thanks in advance, Valentina.
