Link Key
Link Key is a unique, internally generated, access code. Link Keys are generated automatically when devices are Paired or when Authentication is enabled.
Link Keys are created by combining
•The Passkey
•The Bluetooth Device Address
•An internally generated random number.
Pairing Devices
Pairing allows you to avoid entering access information each time a connection is attempted. Paired devices share a unique Link Key, which they exchange when connecting.
Note: The mate of a pair will always appear in My Bluetooth Places, even if the mate is not turned on or is out of connection range.
Paired devices remain paired even when
•One of the devices is not powered up
•A service connection is interrupted or the service stopped
•One or both devices are rebooted.
When Authentication is enabled devices are paired the first time they attempt to connect, after a successful passkey exchange.
To pair devices before attempting a connection
•In the Windows System Tray,
•The Bluetooth Security dialog box appears and Bluetooth for Windows performs a device inquiry to update the list of devices in the area. After the inquiry is complete:
oIn the Found Devices Panel of the dialog box, click the name of the device to be paired
o Click the Execute Pairing button.
•In the Bluetooth Passkey Request dialog box, enter the Bluetooth Passkey
•Click the OK button.
Note: The check box on the main screen, when selected, permits all services to connect without Authorization.
