About

bluetooth

The Bluetooth wireless technology is a worldwide specification for a small-form factor, low-cost radio solution that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. The specification is developed, published and promoted by the Bluetooth Special Interest Group (SIG).

features

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 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

The current set of supported profiles is available here.

platforms

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 and EM64T (x86-64)
  • SUN SPARC 32/64bit
  • PowerPC 32/64bit
  • Intel StrongARM and XScale
  • Hitachi/Renesas SH processors
  • Motorola DragonBall

distributions

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

  • Debian GNU/Linux
  • Ubuntu Linux
  • Fedora Core / Red Hat Linux
  • OpenSuSE / SuSE Linux
  • Mandrake Linux
  • Gentoo Linux
