EVICES
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.
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:
1. In the Windows System Tray, right-click the Bluetooth icon, then Setup and
select Security from the submenu.
2. The Bluetooth Security dialog box appears and BTW performs a device inquiry
to update the list of devices in the area. After the inquiry is complete:
3. In the Found Devices pane of the dialog box, click the name of the device to be
paired
4. Click the Execute Pairing button.
5. In the Bluetooth Passkey Request dialog box:
6. Enter the Bluetooth passkey
7. Click the OK button.
The check box on the main screen, when selected, permits all services to connect without
Authorization.
When devices are paired, the configuration information is saved on both devices. Devices
remain paired until the relationship is broken on both devices.
To break a paired device relationship
•
In the Windows System Tray, right-click the Bluetooth icon, then Setup and
select Security from the submenu.
•
From the Bluetooth Security dialog box, in the Paired Devices list, select a
device, click the Delete button and then click the Done button.
Pairing must be broken on both devices.

ASSKEY
A Passkey is an alphanumeric string up to 16 characters in length. Passkeys are also
called PIN codes, or Personal Identification Numbers.
In BTW, passkeys are used in the Authentication and Encryption process.
