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.*

Hey there! I had the same problem when installing Windows 10 from Windows 8.1. The secret lies with turning on compatibility mode of the Atheros driver to the last known Windows version it worked with (In my case, Windows 8). I discovered this through a Reddit thread, a guy figured this out and only posted there. His Posting:

https://www.reddit.com/r/sysadmin/comments/3r4450/bluetooth_ar3012_and_windows_10_not_working/

Basically, uninstall all bluetooth drivers from device manager, restart computer. Then download the driver BT-8.0.1.305/318 from the Atheros website. Type "Run Programs Made for Previous Versions of Windows" into search bar on Windows. Be sure to follow his steps, run as administrator, compatibility with Windows 8, etc. Reboot computer. You tinker with compatibility troubleshooter enough and have the correct driver installed, it will fix it.

Do Crionsynx or Lee L. have any other suggestions about what I can do? I tried rolling back the Bluetooth driver but that hasn't helped. I have a feeling the problem lies with the last Windows 10 update, which has rendered my devices incompatible, and on other forums I have seen advice to revert to Windows 8.

1. The speaker is a Sony SRS-X55, and I also have Skullcandy Hesh 3 headphones which fail to connect too.
2. Yes, both these devices work on my iPhones and iPod.
3. Bluetooth is turned off on my phones and iPod when I try to connect.
4. I have tried 'discovery' mode on headphones and speaker, but it still fails to locate them.
I don't know if this will help, but when I open the 'events' tab on my Bluetooth driver, I get the following info:

And in the information box under that:

Device USB/vID_0CF3&PID_3004/Alaska_Day/2006 requires further installation.

Sorry to copy so much information, but I thought it might be of some help!

Thanks for trying. I have a couple of questions below:
1. What is the model of your speaker?
2. Does your speaker work on other device like phone?
3. Is your speaker currently paired to another device like phone? If so, could you please turn off the Bluetooth of your phone in the mean time?
4. Lastly, most BT speaker / headphone needs to become ready to be discovered before you can pair them. It is usually done by holding the power button longer until a notification sound is heard. Could you please try that as well?
Thank you so much for your cooperation Wayne.

Regards,

Lee
