Frequently Asked Questions
What is “pairing”?
Pairing (or bonding) is a concept introduced to create a first time recognition of what devices are allowed to
communicate with each other or which devices belong together. Without an initial pairing, devices can usually
not establish a communication session. Directions for pairing devices appears in Chapter 3: Using the Bluetooth
USB Adapter.
What type of security does Bluetooth employ?
Bluetooth has built-in 128-bit encryption, which runs automatically.
What is a Bluetooth PIN code?
This is a unique password set by the user. When devices are paired or when Bluetooth-enabled devices are
accessed, this code is requested for greater security. The PIN code is case-sensitive and can be alphanumeric
(numbers or letters). The PIN code must consist of one or more characters.
