Encyclopedia > Bluetooth stack

A Bluetooth stack refers to an implementation of the Bluetooth protocol stack. Look up Implementation in Wiktionary, the free dictionary. ... Bluetooth logo This article is about the electronic protocol named after Harald Bluetooth Gormson. ... A protocol stack (sometimes communications stack) is a particular software implementation of a computer networking protocol suite. ...


Bluetooth stacks can be roughly divided into two:

  1. General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers. Support for additional Bluetooth profiles can typically be added through drivers.
  2. Embedded system implementations intended for use in devices where resources are limited and demands are lower, such as Bluetooth peripheral devices.

Generally, only a single stack can be used at any time: switching usually requires uninstalling the current stack, although a trace of previous stacks remains in the registry[citation needed]. However, there are some cases where two stacks can be used on the same computer, each using their own separate Bluetooth radio hardware. A Bluetooth profile is a wireless interface specification between devices that use Bluetooth-based communication. ... A device driver, or software driver is a computer program allowing higher-level computer programs to interact with a computer hardware device. ... A router, an example of an embedded system. ... In computer hardware, a peripheral device is any device attached to a computer in order to expand its functionality. ...

General-purpose implementations

Windows

Widcomm

Widcomm was the first Bluetooth stack for the Windows operating system. The stack was initially developed by a company named Widcomm Inc., which was acquired by Broadcom Corporation in April 2004.[1] Broadcom continues to license the stack for inclusion with many Bluetooth-powered end-user devices. Windows redirects here. ... Broadcom Corporation (NASDAQ: BRCM) is a supplier of integrated circuits for broadband communications especially massive high-speed networks including ICs for set-top boxes, cable modems, servers, and LANs and home networking devices. ... To licence or grant licence is to give permission. ... Economics and commerce define an end-user as the person who uses a product. ...


An API is available for interacting with the stack from a custom application. For developers there is also a utility named BTServer Spy Lite bundled with the stack (some vendor-tied versions excluded) which monitors Bluetooth activity on the stack at a very low level - although the category and level of trace is configurable. This stack also allows use of RFCOMM without creating a virtual serial port in the operating system.


Microsoft Windows stack

Windows XP includes a built-in Bluetooth stack starting with the Service Pack 2 update, released on 2004-08-06. Windows XP is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, notebook computers, and media centers. ...

Prior to this, Microsoft released a QFE of its Bluetooth stack for Windows XP Service Pack 1 labelled as QFE323183. Microsoft only released this directly to third-party companies and did not directly release it to the public. The third-party companies were then allowed to release the QFE as part of their own Bluetooth device's software installation. Microsoft no longer supports this QFE. QFE is a three letter acronym which can have meanings in aviation, in software development, and in internet usage. ... Windows XP is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, notebook computers, and media centers. ...


Windows Vista also includes a built-in Bluetooth stack which is an expansion over the Windows XP Bluetooth stack. In addition to supporting more Bluetooth profiles than Windows XP Service Pack 2, it also supports third-party driver development which enables third-parties to add support for additional Bluetooth Profiles. This was lacking in the Windows XP Service Pack 2 built-in Bluetooth stack, which only allowed application development on top of the Microsoft Bluetooth stack, which some observers felt slowed the adoption of the Microsoft Windows Bluetooth stack. This stack does however provide RFCOMM support using sockets instead of virtual serial ports. Windows Vista (pronounced ) is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media centers. ... Windows XP is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, notebook computers, and media centers. ...
