Hi, My Laptop Bluetooth device when activated doesn't discover any active Bluetooth devices around. Please can someone review the below setup and provide help at the earliest. Thanks in advance OS: Windows 10 Home Laptop: HP Pavilion G6-2005AX Notebook PC In Device Manager I see the following setup Under Bluetooth Icon Bluetooth Device (RFCOMM Protocol TDI) Properties->General Devices Status: This device is working properly Device Type: Bluetooth Manufacturer: Microsoft Location: on Qualcomm Atheros AR3012 Bluetooth 4.0 Adapter Properties->Driver Driver Provider: Microsoft Device Date: 6/21/2006 Driver Version: 10.0.18362.1 Properties->Details Hardware Ids: BTH\MS_RFCOMM Microsoft Bluetooth Enumerator Properties->General Devices Status: This device is working properly Device Type: Bluetooth Manufacturer: Microsoft Location: on Qualcomm Atheros AR3012 Bluetooth 4.0 Adapter Properties->Driver Driver Provider: Microsoft Device Date: 6/21/2006 Driver Version: 10.0.18362.693 Properties->Details Hardware Ids: BTH\MS_BTHBRB Qualcomm Atheros AR3012 Bluetooth 4.0 Adapter Properties->General Devices Status: This device is working properly Device Type: Bluetooth Manufacturer: Qualcomm Atheros Communications Location: Port_#0004.Hub_#0003 Properties->Advanced Manufacturer Id: 69 Firmware Version: HCI 5.258 / LMP 6.1 Properties->Driver Driver Provider: Qualcomm Atheros Communications Device Date: 9/3/2019 Driver Version: 10.0.3.22 Properties->Details Hardware Ids: USB\VID_0CF3&PID_311D&REV_0001 USB\VID_0CF3&PID_311D Under Network Adapters Icon Bluetooth Device (Personal Area Network) Properties->General Devices Status: This device is working properly Device Type: Network adapters Manufacturer: Microsoft Location: on Qualcomm Atheros AR3012 Bluetooth 4.0 Adapter Properties->Driver Driver Provider: Microsoft Device Date: 6/21/2006 Driver Version: 10.0.18362.1 Properties->Details Hardware Ids: BTH\MS_BTHPAN

Also, to add: Microsoft updates will try to update to newest version. You have to rollback to previous driver if this happens, by going into the properties menu of the driver within driver manager and selecting the rollback option. Then, you have to use the troubleshoot manager of updates wushowhide to prevent it from occurring. I wish Microsoft would just fix their problem. Good grief.

Qualcomm Atheros AR3012 Bluetooth not working in Windows 10

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.*
