What to do if bluetooth does not work on Linux Mint?

Question

linux

In short, not so long ago I wanted to connect bluetooth headphones, but there were problems, to the point that the system seems to see, but it seems that it does not see the adapter. blueman and blueberry don't see it that way.

"Oct 06 19:57:56 xanos-laptop bluetoothd[4191]: No Bluetooth address for index 0" on this line you can understand that the problem is with the bluetooth address (as I understand it, on the bus). What to do next - I do not know.

sudo hcitool scan output

Device is not available: No such device

"sudo lsusb | grep Bluetooth" generally has an empty output

PS Literally a month ago everything worked, no operations were performed before and after with bluetooth

Answer 1

reinstall the driver

Answer 2

Can't init device hci0: Cannot assign requested address (99)
I've been struggling with this for a day, but the result is the same
