deactivate bluetooth service from terminal

At this date, chrubuntu is still in alpha stage, the community around it is still in development process, so last night I did some changes on it now this morning I can't deactivate my bluetooth service from graphical mode, so, let's do this from terminal.

1. first let see if it's running:
  service bluetooth status

I got something like this:
bluetooth start/running, process 341


2. now let's stop that process:
sudo service bluetooth stop

if you check it again  the process has been stopped.

and that's it
