Bluetooth Device Identity
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;
00:40:F4:39:57:6D 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.
Encryption
Encryption translates data into an unreadable format using a secret key or
password. Decrypting the data requires the same key or password that was
used to encrypt it.
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, manual entry of the passkey is not required.
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 each time they connect.
Paired devices remain paired even when
 One of the devices is not on
57
 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.
