Description Etienne URBAH 2018-03-15 21:28:42 UTC

On a machine WITH bluetooth hardware, the 'bluetoothctl' command works correctly.
For example, the command 'bluetoothctl < /dev/null' terminates correctly.

On a machine WITHOUT bluetooth hardware, the 'bluetoothctl' command systematically hangs.
Even the command 'bluetoothctl < /dev/null' systematically hangs.
