Authentication is used to verify identity; it requires a passkey or link key from the remote 
device. When a remote device attempts access, a visual and/or audio warning notifies the 
local operator. 

If the notification is ignored, access is denied after a preset timeout. 

When devices are “paired,” those devices automatically exchange a Link Key and 
Authentication is carried out without operator intervention.

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.

Decrypting the data requires the same key or password that was used to encrypt it.

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.
