Every Bluetooth device has a unique Bluetooth Device Address (BDA) assigned to it during the
manufacturing process. This address cannot be changed by the end user.
A device’s BDA is usually displayed in hexadecimal format; 00:D0:B7:03:2E:9F is a valid BDA.
Each Bluetooth device also has an operator-configurable, user-friendly name to help distinguish it
from other devices. The user-friendly name may be up to 99 alphanumeric characters in length
and may contain spaces. “My Personal Computer” is a valid user-friendly name.

Pairing allows you to avoid entering access information each time a connection 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 connection 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 “Unpair Device”
from the shortcut menu.
