I had the same issue on a Lenovo laptop. The command

 sudo rfkill unblock all

mentioned by @vanvugt solved the issue for me.

Linux 4.13.0-16-generic

Mentioned "rfkill unblock all" command actually enables bluetooth, which I'd like to keep disabled.
bluetoothd should check if device is blocked and do not try setting mode for such devices.

[Daniel van Vugt (vanvugt)]

OK, thanks. This is then a simple enhancement request to reduce excessive logging, per comment #18.
