Setting Communication Preferences
205
The discovery process is typically initiated by an application. For example, when
you connect your handheld with a mobile phone using the Phone Link application,
Phone Link discovers phones equipped with Bluetooth technology within range in
order to connect with one of those phones.
You can use the Discoverable and Bluetooth settings to achieve three discovery
states on your handheld. The following is a description of setting combinations
and the resulting discovery states.
■ Bluetooth Off: When the Bluetooth setting is off, other users cannot discover
your handheld. This is similar to locking your door with a dead bolt, a security
chain, and disabling the door bell. When Bluetooth is off, you cannot access the
Discoverable setting. See “Turning Bluetooth communication on and off”
earlier in this chapter for instructions on turning Bluetooth communication on
and off.
■ Bluetooth On and Discoverable No: When your handheld and Bluetooth are on
and the Discoverable setting is set to No, you can receive connections only from
devices with which you have previously formed a trusted pair. This is similar
to locking your door with a dead bolt and disabling the door bell, but any
friends who already have the key can enter. By default, the Discoverable setting
is enabled when Bluetooth is on.
■ Bluetooth On and Discoverable Yes: When your handheld is on, Bluetooth is on,
and the Discoverable setting is set to Yes, you can receive connections from any
Bluetooth device. You are automatically connected with devices with which
you have previously formed a trusted pair, but you can refuse invitations to
connect with unrecognized devices. This is similar to locking your front door
with a dead bolt and enabling the door bell. Friends who already have the key
can enter freely, and if someone without a key rings the bell to request a
connection, you can choose to open the door or ignore the request.
