The issue is occasionally not present after I restart the computer, but most of the time it is. Press Windows Key + R, then enter services.msc in the window that appears In the list of items, double-click Bluetooth Support Service Change the startup type to Automatic and click the Start button to start the service (Check for the dependencies of this service in the Dependencies tab and make sure these are also set to automatic). Independent of Ubuntu version, same issue on 20.04, 20.10 & 21.04. ERROR: Unable to start Bluetooth Stack Service, failing to Initialize device control panel. This mechanism enables Bluetooth radios to recover from hardware failures that lead to malfunction, loss of connectivity, or unresponsiveness to operational commands. The issue is persistent across all kernels (as far as I have tested) on this device except 5.4.x. Bluetooth Radio Reset and Recovery is a technology in Windows 10, version 1803 and later that introduces a robust reset and recovery mechanism for Bluetooth radios. Note that concerning WiFi, it works as expected. So, in short, NetworkManager is unable to activate the Bluetooth interface.
Only then a subsequent systemctl restart bluetooth command seems to make it work again and change to "on" state as well as start listing nearby devices. error message unable to start bluetooth stack service This happened on two computers after downloading norton security suite. So it seems the NetworkManager is unable to activate it back. However, if I switched it back off and on using NetworkManager applet, it is again not working and Bluetooth stays in "off" state. It immediately works and connects to devices correctly. Indeed, it is "soft blocked" : # rfkill list
Bluetooth Device Drivers are operating system and device specific.In other words, for the same Bluetooth Device, you are likely to require a different Driver for Windows 10, Windows 8 or Windows 7 to the Driver you would need for Windows XP.
I was already thinking about using the Pi 3 in my Raspberry PiStation build so that I could do away with the extra dongles.

Now that the Raspberry Pi 3 comes with Bluetooth and WiFi built-in, people (including me) were excited at the increased flexibility this offers.
By default, after a fresh boot, the Bluetooth service is unable to start correctly and does not find any device to pair with nor the NetworkManager's Bluetooth indicator changes from "off" to "on" state.īus 002 Device 002: ID 8087:0029 Intel Corp.
