6.5 Link Key
A unique, internally generated, access code based on a passkey, the Bluetooth
Device Address and an internally generated random number. Link keys are
generated automatically when devices Pair. After a link key is generated, man-
ual entry of the passkey is not required.
6.6 Pairing Devices
Pairing allows you to avoid entering access information each time a connec-
tion is attempted. Paired devices share a unique link key, which they exchange
each time they connect.
" Note: The mate of a pair always appears in My Bluetooth
Places, even if the mate is not turned on or is out of connec-
tion range.
Paired devices remain paired even when
• One of the devices is not on
• A service connection is interrupted or the service stopped
• One or both devices are rebooted.
To Pair with another device:
If Secure Connection is enabled, devices will pair automatically the first time
they connect (a passkey must be successfully exchanged).
To pair with a device manually:
In the Folders pane of My Bluetooth Places, right-click a device, select Pair
Device from the shortcut menu, and then follow the on-screen instructions.
Remove Pairing
In the Folders pane of My Bluetooth Places, right-click a paired device and
select UnpairDevice from the shortcut menu.
6.7 Passkey
A Passkey is an alphanumeric string up to 16 characters in length. Passkeys
are also called Personal Identification Numbers, or PIN codes.
A passkey may be required if the Secure Connection option is enabled for a
Bluetooth service or application.
