Pairing Devices
Pairing devices establishes a rather permanent relationship between two devices. It creates a
permanent security link between the two and enables easy access to all the available services
without having to enter access information every time a connection is attempted. Paired devices
share a unique Link Key that they exchange when they are establishing the connection. Moreover,
the mate of a pair will always appear in My Bluetooth Places even if the mate is disconnected or
is beyond connection range.
Paired devices remain paired even in the following scenario:
 One of the devices is not powered up.
 A service connection is interrupted or the service stopped.
 One or both devices have been rebooted.
When Authentication is enable, devices are paired the very first time they attempt to connect, but
only after a successful passkey exchange.
To pair devices before attempting a connection:
1. In the Windows system tray, right-click the Bluetooth Tray icon.
Select Setup and then select Security from the submenu.
2. The
Bluetooth Security dialog box
appears, prompting BTW to
perform a device inquiry to update its list of devices in the area.
3. Once the inquiry is complete, you will see a Found Devices pane
in the dialog box. Click the name of the device to be paired.
4. Click the Execute Pairing button.
5. The Bluetooth Passkey Request dialog box opens, prompting
you to enter a
Bluetooth passkey
.
6. Click OK.
If you select the checkbox on the main screen, you will be permitted to connect to all services
without Authorization. When devices are paired, the configuration information is saved on both
devices. These paired devices will then remain “paired” until the relationship is broken on both
devices.
To break a paired device relationship:
1. In the Windows system tray, right-click the Bluetooth Tray icon.
Select Setup and then select Security from the submenu.
2. The Bluetooth Security dialog box appears, displaying a
Paired Devices
list.
3. Select a device from the list and click the Delete button.
