Trying to execute below command (with bluez-5.37 and Ubuntu 14.04):

Well, the message means that another/running daemon is using the same bus name.

• Check using:

  $ ps aux | grep blue
  sneetsh+ 2226 0.0 0.0 333592 5432 ? Ssl 08:00 0:00 /usr/lib/x86_64-linux-gnu/indicator-bluetooth/indicator-bluetooth-service
  sneetsh+ 2318 0.0 0.6 605972 48636 ? Sl 08:00 0:00 /usr/bin/python /usr/bin/blueman-applet
  sneetsh+ 2765 0.0 0.0 31484 3348 ? S 08:00 0:00 /usr/lib/bluetooth/obexd
  root 5327 0.0 0.0 29864 4504 ? Ss 09:03 0:00 /usr/lib/bluetooth/bluetoothd
  sneetsh+ 5361 0.0 0.0 9592 2192 pts/2 S+ 09:04 0:00 grep --color=auto blue

  Or system monitor (graphic user interface).

• Another option, d-feet, it is DBus browser. In the bottom left corner, you can see the owner process.

Then sudo kill it or sudo service ... stop it if it's service. For default Ubuntu setup, it has a service, so run:

rfkill block bluetooth
sudo service bluetooth stop

Run your local daemon then enable bluetooth again

rfkill unblock bluetooth

Without switching of bluetooth, the bluetooth service will re-spawn again.
