Recently bluetooth is giving a lot of problems in 18.04.5 LTS (I have the latest update), specially when I awake the laptop (I have no TLP installed). I updated bluez and nothing changed. Bluetooth can't connect and does not seem to power on, even after restarting the service.
I find these errors on red when I check the status of bluetooth after restart:
Version mismatch for sixaxis
Loading LTKs timed out for hci0
Failed to set mode: Failed (0x03)
I also get Failed to set power on: org.bluez.Error.Failed when I try to power on on bluetoothctl
Log
$ sudo service bluetooth restart
$ sudo service bluetooth status

Note
To make it work again, I need to reboot or restart bluetooth with
rfkill block bluetooth
rfkill unblock bluetooth
This is really annoying because I'm using it for a bluetooth keyboard, and every time it fails to connect I have to switch to the laptop internal keyboard.
