How to turn off bluetooth visibility in OS X Yosemite?

Question

Bluetooth

Spotlight on the settings and searching the Internet and the apple community did not give an answer. Can't turn off visibility of macbook air with Yosemite installed on it. Same with MacBook Pro. Has anyone already experienced something similar?

Go to System Preferences -> Network.

On the left, select bluetooth, below we see the button Configure Bluetooth device. We find ourselves on this screen

and use the button to enable / disable bleutooth.
Or do you want the bluetooth to work but not be available to unfamiliar devices? no, that's not possible
