I bought this bluetooth usb key usb-bt4le
It’s working but the Bluetooth is very unstable.. Fortunately we can use some commands to avoid restarting the computer 😉
Install bluetooth module
Then plug the usb dongle
You’ll maybe need to restart in order for the Bluetooth icon to show up.
You can now pair with your devices.
Deal with Crashes
Bluetooth icon disappear/crash:
Sound icon disappear/crash:
then check if output sound peripherals are back (for gnome):
