I found this book an extremely helpful tool for understanding the Bluetooth landscape. It clearly and concisely explains the specification, and the various protocols and profiles--even for laypeople.The book is laid out in a logical manner, with helpful diagrams and charts throughout. Readers of this book who are Bluetooth novices will become fascinated with the specification and its possibilities. I look forward to a second edition with updates on new versions of the Bluetooth spec.
