[Bug 1565940] Re: bluetoothctl systematically hangs when there is no bluetooth hardware

My particular use case is to detect, inside a shell script, if there is
any bluetooth hardware at all.

Since 'bluetoothctl' systematically hangs when there is NO bluetooth
hardware, I can NOT use the 'bluetoothctl' command to achieve this use
case.

But I have found a good alternate method :

if  rfkill  list  |  grep  -q  -i  Bluetooth;  then  ...;  fi

So, the issue is NOT blocking for me.

But I suggest that 'man bluetoothctl' should indicate that
'bluetoothctl' waits (possibly indefinitely) for answers from the
'bluetoothd' daemon, and therefore is NOT adequate for scripting.
