Since, the Fedora 20 is migrating to Bluez5  and there is no support for bluetooth in Mate Desktop in Fedora 20. I was about to find some workaround to use bluetooth headset. Bluedevil is currently not working.
$ bluetoothctl [bluetooth]# power off [bluetooth]# power on // [bluetooth]# agent on [bluetooth]# connect 20:16:D8:5A:19:DC
The power off and power on sequence is necessary for correct operations. It could be difficult to find solution for additional errors.
The selection of audio output is task for pulse audio. The mate-volume-control, standard audio configuration tool, cannot select audio output.
