Bluetooth Stopped Working on Windows 10 (Qualcomm QCA9377)

I was using my bluetooth headphones yesterday and everything was working fine. When I returned to my computer, which was still on with everything unchanged, the bluetooth function no longer worked. I've tried everything I could find online but nothing has worked.

  • When attempting to connect to Bluetooth, the computer says to turn bluetooth on. There is no option to turn bluetooth on.
  • Under device manager, there is the Qualcomm QCA9377 Bluetooth item. It often says "Windows has stopped this device because it has reported problems. (Code 43)", but disabling it as well as uninstalling and reinstalling it have both failed. I tried both downloading it from microsoft and from the manufacturer (Dell) and both have failed consistently with multiple attempts.
  • Troubleshooting the bluetooth feature sometimes yields "bluetooth drivers have failed", but ALWAYS yields "Bluetooth Radio Status - Not Fixed".
  • I have restarted and shut down countless times.
  • I have used the task manager to manually start every bluetooth process but there have been no results.

I know there are other threads like this but not a single one has a working solution of any kind, and most of the threads die out before the issue is resolved. Has anyone ever found a solution to this issue?

Update: I have also rolled back the driver of the Qualcomm network adapter multiple times, with no effect.

Powering off and pulling the power on my Dell Inspiron laptop worked as well.  I did have to delete the failed USB entry and then rediscover, but this worked. Thanks for posting. Not exactly sure why a power off and more importantly pulling the power WHICH IS THE ACTUAL step that worked for me, since I tried just powering off first and that didn't help, fixes the issue though.

    This worked for me on my Dell desktop PC as well.

    • First, the Bluetooth driver was hidden, so had to go to View > Show Hidden Devices in the Device Manager
    • Then I ended up removing the Qualcomm driver, shutting down, and unplugging the PC.
    • I plugged it back in after a few minutes, booted up and the driver appeared to be functioning as intended, and I was able to see the Bluetooth on/off toggle under Settings > Bluetooth & other devices

    Thank you!

    Uninstalling the malfunctioning USB driver and then restarting (unplugged) worked for me! 

    Restarting alone didn't do anything. 

    For people who end up reading this, look into the USB drivers like in Allan's post. Took me hours and hours to find it but that was the fix for me. 

    Also restarting took much longer while the bluetooth device wasn't working, it seems like the computer tried to install the drivers but failed (making restart take longer as drivers are installed on boot) and ending up with the unknown USB device driver.
