CHAPTER 17
Connecting Wirelessly to Other Devices
What is device discovery?
Discovery is the process in which your handheld searches for other Bluetooth devices within its
range (approximately thirty feet). As each device is discovered, it shows up in your Discovery
Results. After you find the devices you are looking for, you can select the devices with which you
want to connect.
The Bluetooth application on your handheld can be turned on and off, and the application has a
Discoverable setting that can also be turned on and off. 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 and a security chain, and disabling the
doorbell. When Bluetooth is off, you cannot access the Discoverable setting.
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 doorbell, 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 communicated, 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 doorbell. 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.
