Bluetooth Demystified [Kindle Edition]

A quantitative example of a gross error that should have been caught well before publication, would be the claim, on more than one occasion, that the Bluetooth packet time slots are 625 ms (milliseconds) long as opposed to 625 us (microseconds). This is such a fundamental error it is almost laughable (if it weren't for the fact I paid good money for this book).

Another quantitative example would be in the description of CVSD modulation. Figure 2.7 which shows the relationship of the reference voltage to the signal voltage, with the axes unlabeled so we have to assume the x axis is time and the y axis is voltage, isn't monotonic along the time axis. i.e. the signal actually doubles back on itself with respect to the time axis. This is such a fundamental error it is almost laughable. (Sound familiar.) This error is such that it leads me to believe that the author did not have a good understanding of CVSD modulation.

Silly things like incorrect acronyms should have been caught by any proofreader; VIFR for Very Fast Infrared for example (again on more than one occasion).

This book was clearly rushed out, bypassing any proper review process, to be the first guide to Bluetooth technology, and unfortunately it shows.

I just received my copy of Bluetooth Revealed by Miller and Bisdikian, and from what I have read so far I would have to recommend this over Bluetooth Demystified (by a very large margin indeed).

There were also mispelled commercial products (page 7) of Cisco's Aeronet (should be Aironet), but the accompanying digital photos clearly showed Aironet. This is one of the examples where both the author and McGraw-Hill's book editor failed their proofreading and/or research tasks.

The Bluetooth protocol descriptions came pretty much straight out of the Bluetooth specifications, without any comments or analyses. This indicates that that author, in this reviewer's opinion, has limited understanding on how or why the Bluetooth teams arrived at certain technical decisions. The last chapter on Global Scheme of 3G Wireless has little to do with Bluetooth.

I'm rather disappointed with the book in general since it contains information that can be downloaded directly from the Bluetooth Web site (for free). Rather than trying to rush out the "first" Bluetooth book, both the author and publisher should focus on delivering quality content rather than another door stop. Save your $US49.95 for another book.

Normally, this reviewer does not write such a strong opinion unless the book is extremely bad or good. Unfortunately, I am mystified on why this book was published at all.
