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.*

    Hi.

    1. Bluetooth device - do you mean a USB bluetooth adapter? No

                                    - do you mean connecting other bluetooth devices to the built-in adapter? Yes and they all fail because the built-in bluetooth adapter is always (most of the time) disabled by Windows and I have to right-click enable it manually.

    1. Yes, the bluetooth driver is the most up to date from Killer Networking website.

    Remember, I am using Ubuntu now, and I have not had this problem at all.

    Hi,

    In most cases, this issue may be caused by an outdated Bluetooth driver.

    For us to provide the best resolution possible, we'll be needing additional information:

    • Have you tried using a different Bluetooth device? If yes, are you experiencing the same problem?
    • Have you check if the Bluetooth driver of your computer is up-to-date?

    We'll be waiting to your reply.

    Hi all

    I've been having this problem a looooong time. In fact come to think of it, it was since I upgraded to Windows 10.

    The bluetooth driver always run into a problem at reboot. Under Device Manager, it is listed as disabled.

    What I have to do is, I have to right-click & disable the disabled driver, and then right-click & enable it again. Under most circumstances, this will get my bluetooth 4.1 Logitech MX Master mouse working again with the desktop after waiting some 2-3 minutes.

    In some other annoying cases, the bluetooth would not allow itself to be enabled under Device Manager. I will have to completely uninstall and remove driver software for the device, and try to install the drivers again. I don't even know which ones are the real correct drivers (if they're correct, they should be working always right?)

    Right now, the temporary working driver is listed as :

    Driver Provider: Qualcomm Atheros Communications

    Driver Date: 24/06/2015

    Driver Version: 10.0.0.102

    Digital Signer: Microsoft Windows Hardware Compatibility Publisher

    Once I reboot, this driver will be disabled by Windows again.

    Note that the problem is only with Windows 10.

    I run Ubuntu 16.04 most of the time now from early last month, and have never had a bluetooth problem. And I don't remember having suffered bluetooth problems with my mouse when I was using Windows 7.
