Basic Bluetooth Roles and Concepts
Pairing: Pairing is the process in which two devices enabled with Bluetooth wireless technology create a secure link in order to share information. Each of the two devices is configured in a different pairing mode. These modes are:
- Acceptor – the device configured as an acceptor accepts a connection from the other device. It does not attempt to actively connect to any other device. It may require some security information from the initiator device before accepting the connection.
- Initiator – the device actively searches for (page) and connects to the other device (which must be discoverable and configured as an acceptor). If security settings have been configured on the initiator device, it may need to present these settings to the acceptor to complete the connection.
The pairing process begins when the initiator device broadcasts an inquiry to search for discoverable Bluetooth addresses of acceptor devices.
MAC address: Bluetooth devices such as scanners are identified by a unique 12 hexadecimal (base 16) address (i.e. composed of the numbers 0-9 and letters A-F, typically expressed in pairs separated by “-“ or “:” such as 08-00-2B-1F-3D-47 or 00:00:2F:E0:BC:7C). This address is sometimes called the Bluetooth MAC address, or simply the MAC (Media Access Control) address.
