BlueZ provides support for the core Bluetooth layers and protocols. It is flexible, efficient and uses a modular implementation. It has many interesting features such as: * Complete modular implementation * Symmetric multi processing safe * Multithreaded data processing * Support for multiple Bluetooth devices * Real hardware abstraction * Standard socket interface to all layers * Device and service level security support Currently BlueZ consists of many separate modules: * Bluetooth kernel subsystem core * L2CAP and SCO audio kernel layers * RFCOMM, BNEP, CMTP and HIDP kernel implementations * HCI UART, USB, PCMCIA and virtual device drivers * General Bluetooth and SDP libraries and daemons * Configuration and testing utilities * Protocol decoding and analysis tools * Audio Service witch gives support to profiles: HSP, HFP, AVDTP, A2DP, AVRCP * Input Service profiles: HID * Network Service profiles: PAN * Serial Service profiles: RFCOMM
