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

  1. remove AR3012 & its drivers completely from 20H1, later let 20H1 detect it as Generic Bluetooth Radio.
  2. download Qualcomm driver v10.0.1.15 from Microsoft Catalog website, install this driver via driver upgrade.
  3. after v10.0.1.15 being installed, you might see additional device named in "Bluetooth LE" as the one in the Kirill's figure.
  4. try to connect any BT device you couldn't connect after upgrading to 20H1, make sure the AR3012 really WORKS.
  5. 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.*

    Thankyou Lee.

    I have followed your instructions, but it has not worked. When I select 'Add a device', with my wireless

    speaker standing next to the computer and trying to connect, it just searches and searches but nothing

    comes up.

    If I choose the third option down, 'Everything Else (Xbox controllers with wireless adapter, DLNA and more',

    then it detects two objects - our TV and a fire stick. But with the top option, 'Bluetooth devices', nothing

    at all I'm afraid.

    Is there anything else I could try?

    Hi WayneSmith_271,

    My name is Lee an Independent Advisor.

    Please try this:

    • Go to device manager > Uninstall Bluetooth driver & restart the computer
    • To re-install the Bluetooth driver, go back to device manager and click the Action Menu > Scan for hardware change
    • If the Bluetooth driver did not come back, you may also go to Settings > Update & Security and check for updates to re-install the Bluetooth driver
    • After the BT driver is back, kindly go to Settings > Devices > Bluetooth & other device and turn on Bluetooth
    • Before adding the headset, make sure you make you PC can be discovered by other devices, to do that look at the right side in the same option and lick on "More Bluetooth option" > under discovery check "Allow Bluetooth devices to find this PC" > OK
    • Now Add the Bluetooth device and test if this step resolve the problem

    If my suggestion is not helpful, you may always send me a reply and I will respond back as quickly as I can. Thank you and have a nice day!

    Sincerely,

    Lee | Independent Advisor

    Thanks, I've just tried the Samsung Update Tool. On the Microsoft Store page it says that this does not support Windows 10. I installed the update tool, input my PC model number, and it downloaded a Bluetooth Driver (version 8.0.1.306).  When I attempt to install it, I get the repeated message 'The existed ProductVersion is higher than your ProductVersion. Installation quit'.
