Somehow by default I can't rename my notebook's Bluetooth.
You need to install blueman package for this.
$> sudo apt-get install blueman
and run
$> blueman-manager
to rename your bluetooth.
But I can't pair my bluetooth mouse using this, blueman.
So I get back to 'gnome-control-center bluetooth' (you can click at bluetooth icon at main-bar) to pair my mouse.
