This article is about the Bluetooth wireless specification.
Bluetooth is an industrial specification for wireless personal area networks (PANs) first developed by Ericsson, later formalized by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1999. It was established by Sony Ericsson, IBM, Intel, Toshiba and Nokia, and later joined by many other companies as Associate or Adopter members.
The system is named after a Danish king Harald Blåtand (Harold Bluetooth in English), King of Denmark and Norway from 935 and 936 respectively, to 940 known for his unification of previously warring tribes from Denmark, Norway and Sweden. Bluetooth likewise was intended to unify different technologies like computers and mobile phones. The Bluetooth logo merges the Nordic runes for H and B. This is the official story: however, the actual Harald Blåtand that was referred to in naming Bluetooth was most probably the liberal interpretation given to him in The Long Ships by Frans Gunnar Bengtsson, a Swedish best-selling Viking-inspired novel.
Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.
Bluetooth lets these devices talk to each other when they come in range, even if they're not in the same room, as long as they are within 10 metres (32 feet of each other).
Compatibility of products with profiles can be verified on the Bluetooth Qualification website (http://qualweb.bluetooth.org/Template2.cfm?LinkQualified=QualifiedProducts).
Comprehensive Real-World Guidance for Every Embedded Developer and Engineer
This book brings together indispensable knowledge for building efficient, high-value, Linux-based embedded products: information that has never been assembled in one place before. Drawing on years of experience as an embedded Linux consultant and field application engineer, Christopher Hallinan offers solutions for the specific technical issues you’re most likely to face, demonstrates how to build an effective embedded Linux environment, and shows how to use it as productively as possible.
Hallinan begins by touring a typical Linux-based embedded system, introducing key concepts and components, and calling attention to differences between Linux and traditional embedded environments. Writing from the embedded developer’s viewpoint, he thoroughly addresses issues ranging from kernel building and initialization to bootloaders, device drivers to file systems.

This is a continuation of my experiments in bit-banging full-speed USB on the Propeller. I have the basic host controller working reasonably well now, so I started trying to do something a bit more “useful” with it by implementing a simple Bluetooth stack on top of it.
Bluetooth and USB are both quite complicated, and this project is implementing only tiny fractions of each specification. But I think it’s enough to show that the functionality you actually need in a simple embedded application isn’t that complex- and a lot of the cheap consumer electronics you can get nowadays might actually be more hobbyist-accessable than they appear.
Hanno on the forums found some great $2 Bluetooth dongles on DealExtreme. So I just had to order a few of these and try them out with my work-in-progress software stack. The result:
That’s a Propeller demo board, the $2 dongle (stripped down and attached to a 4-pin header, for convenience) and no other components. The demo here is just scanning for nearby devices, but I also have some basic L2CAP support and I’m working on the SDP server. Currently the stack uses 4 cogs (3 for USB, 1 for Bluetooth) and 12 kB of RAM, but I’m hoping to optimize it.
(Of course, this is only possible because the Bluetooth dongle itself has significantly more RAM and ROM than the Propeller has. Oh, the economies of scale!)
The software is very much a work-in-progress, but you can find it in the Subversion repository, with an MIT-style license.
