Excerpts

Preface to the Second Edition A year later, and another version of the Bluetooth specification released, the Bluetooth World has moved on far enough to justify a second edition of this book. Whilst updating for version 1.1 we've also taken the opportunity to correct a few errors that crept into the first edition, thanks to Don Felton, Bill Saltzstein, Klaus Mehle, Steve Singer, Simon Morris, and everyone else who provided us with errata.Each section of the book has been updated with information on version 1.1 of the Bluetooth specification. Many of the changes have just been clarifications, but here and there functionality has been altered and improved. Where 1.0b and 1.1 are different we have identified the changes, and where relevant included notes on backwards compatibility.For those of you who want a summary of the changes there is an appendix with details on the critical errata which led to version 1.1. This appendix tells you in one place what is different, and why it was altered. Of course as the specification progresses, so does the rest of the community of Bluetooth users. In the past year many new products and components have qualified, and the qualification program itself has matured. Real products have come on the market, and we're starting to see Bluetooth technology in use for real. To reflect those developments you'll find the section on Bluetooth in Context has changed.We've reached version 1.1, but still more progress is being made in many Bluetooth SIG working groups to bring out a new generation of profiles, and to enhance the core Bluetooth specification. As we were updating the book for version 1.1 some draft profiles were put on public release. These profiles open up new applications for Bluetooth devices, so to cover them we've added a whole new section to the book called "Applications--The Bluetooth Profiles". The draft profiles may change slightly before being formally adopted, and more new profiles are due for public release soon. Watch the book's companion web sitehttp://www.phptr.com/bluetooth/bray/index.htmlfor more details: we'll publish these after information is made available in public.
