The overall goal of this project is to make an implementation of the Bluetooth wireless standards specifications for Linux. The code is licensed under the GNU General Public License (GPL) and is now included in the Linux 2.4 and Linux 2.6 kernel series.

BlueZ provides support for the core Bluetooth layers and protocols. It is flexible, efficient and uses a modular implementation. It has many interesting features:

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 seperate 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

The BlueZ kernel modules, libraries and utilities are known to be working prefect on many architectures supported by Linux. This also includes single and multi processor platforms as well as hyper threading systems:

Intel and AMD x86
AMD64 (x86-64)
SUN SPARC 32/64bit
PowerPC 32/64bit
Intel StrongARM and XScale
Motorola DragonBall

Support for BlueZ can be found in many Linux distributions and in general it is compatible with any Linux system on the market.
