About Bluetooth Modes
Bluetooth operates in three different modes:

On.
The Bluetooth radio is turned on and you can use Bluetooth
features.

Off.
The Bluetooth radio is turned off. In this mode, you can neither
send nor receive information by using Bluetooth. You might want to
turn the radio off at times in order to conserve battery power, or in
situations where radio use is prohibited, such as on airplanes and in
hospitals.

Discoverable.
The Bluetooth radio is turned on, and all of the other
Bluetooth devices within range (about 10 meters) can detect your
device and attempt to beam information to it, establish a bond, or
use a Bluetooth service. In this mode, other devices can detect your
device whether or not a bond has been created; however, in order to
receive a beam from another device, you must accept it on your
device, as described in Receiving a Bluetooth Beam.

On and Off Bluetooth and Making Your Device Discoverable.
