Consequently why do I have to link my code to "BlueZ" library. When I actually look at BlueZ code - it uses "HCI" So does the "tutorial" you and I used - to code in C , not C++ - uses "HCI" . That tutorial refers to "bluetooth" library and who knows where that come from. D-Bus runs a daemon called dbus, that facilitates interprocess communication and remote procedure calls in a Linux system. D-Bus acts a little like a telephone operator: Process C can broadcast a message for any process that wants to tune in.

Lastly, PairingAgentWithValidation defines a virtual method without implementation for each method in the Agent1 interface. For example, RequestConfirmation is defined as follows: First, we need to create a socket, that we can accept a connection from. The socket family is PF_BLUETOOTH, socket type is SOCK_SEQPACKET (we want to have a TCP-like socket, not raw), and the protocol is the Bluetooth protocol L2CAP ( BTPROTO_L2CAP ). ssock = socket (PF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_L2CAP);In order to use BlueZ, you need to have at least a 2.4.4 Linux kernel. The 2.4.6 kernel has BlueZ built-in. In case, if you want to use the latest version of BlueZ ( see section 2.1 for download instructions), you should disable native BlueZ support.
