Configuring the MT8850A/MT8852A MT8850A / MT8852A Bluetooth Test Set
Setting Up Authentication Authentication is the process of configuring a Bluetooth unit to connect only to one
specified device. A headset, for example, can be configured to connect only to a specific
mobile phone, and in this case, verification processing is used to ensure that the correct
connections have been established. The MT8850A/MT8852A can be configured to use
authentication during the establishment of a connection.
Note: The MT8850A/MT8852A does not use authentication by default.
The process of authentication involves creating a common key, referred to as the link key,
between the master and slave devices. Security could be compromised if this link key
were sent between devices, so instead, it is generated from a random number and a
Personal Identification Number (PIN) which can be entered into the MT8850A/MT8852A.
If authentication is required but the Bluetooth devices do not have a common link key, the
authentication procedure is completed using the PIN input, and a link key is then created
and stored during the authentication procedure. The link key stored in the Bluetooth
device can then be used during any future connection. Follow the procedure below to
configure the MT8850A/MT8852A to use authentication.
1. Press the hard key.
2. Choose “Equipment Under Test (EUT)”.
3. Press the key.
4. Choose “Authentication Setup”.
5. Press the key.
6. The Authentication setup screen is displayed as shown below.
7. Choose “Authentication” and press the key to toggle between “Disabled” and
“Enabled”.
8. Choose “PIN Length” and press the key.
9. Enter a pin length between 1 and 16 and press the “Enter” soft key.
10. Choose “PIN Code” and press the key.
11. Enter the required alphanumeric value, dependant upon PIN length and press the
“Enter” soft key. The MT8850A/MT8852A will use this PIN key during all subsequent
connections to any EUT.
