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.*

    I've downloaded 21.05.2015 10.0.1.0 version of the bluetooth driver from this link and it's working fine now. The old ones always better...

    After a number of hours that I am ashamed to admit that MS has sucked from my life, I saw this post and did the same as you, but with version 11.08.2016 10.0.1.11, and my same exact problem was resolved. Like you said "The old ones always better..."

    MANY, MANY, THANKS!!!!

    This solution worked for me. I come home from work and try connecting my headphones only to see bluetooth has disappeared from the action center. Went to device manager, bluetooth wasn't showing up. Toggled "show hidden devices", bluetooth does show up there, but all the icons are greyed out. Checked services, bluetooth also showed up there, and showed as "running". Weird. So after about an hour of troubleshooting, including restarting the computer, running the bluetooth troubleshooting(said my device doesn't have bluetooth compatibility), reinstalling the drivers from the manufacturer, the drivers posted on this thread here, nothing was working. Then came across this post, went into the hidden devices in device manager and uninstalled every bluetooth driver, must've been 15 of them. Restarted computer and suddenly, bluetooth is back.
