The First Complete Guide to Bluetooth Low Energy: How It Works, What It Can Do, and How to Apply It


A radical departure from conventional Bluetooth technology, Bluetooth low energy (BLE) enables breakthrough wireless applications in industries ranging from healthcare to transportation. Running on a coin-sized battery, BLE can operate reliably for years, connecting and extending everything from personal area network devices to next-generation sensors. Now, one of the standard’s leading developers has written the first comprehensive, accessible introduction to BLE for every system developer, designer, and engineer.


Robin Heydon, a member of the Bluetooth SIG Hall of Fame, has brought together essential information previously scattered through multiple standards documents, sharing the context and expert insights needed to implement high-performance working systems. He first reviews BLE’s design goals, explaining how they drove key architectural decisions, and introduces BLE’s innovative usage models. Next, he thoroughly covers how the two main parts of BLE, the controller and host, work together, and then addresses key issues from security and profiles through testing and qualification. This knowledge has enabled the creation of Bluetooth Smart and Bluetooth Smart Ready devices.


This guide is an indispensable companion to the official BLE standards documents and is for every technical professional and decision-maker considering BLE, planning BLE products, or transforming plans into working systems.


Topics Include

  • BLE device types, design goals, terminology, and core concepts
  • Architecture: controller, host, applications, and stack splits
  • Usage models: presence detection, data broadcasting, connectionless models, and gateways
  • Physical Layer: modulation, frequency band, radio channels, power, tolerance, and range
  • Direct Test Mode: transceiver testing, hardware interfaces, and HCI
  • Link Layer: state machine, packets, channels, broadcasting, encryption, and optimization
  • HCI: physical/logical interfaces, controller setup, and connection management
  • L2CAP: channels and packet structure, and LE signaling channels
  • Attributes: grouping, services, characteristics, and protocols
  • Security: pairing, bonding, and data signing
  • Generic Access Profiles: roles, modes, procedures, security modes, data advertising, and services
  • Applications, devices, services, profiles, and peripherals
  • Testing/qualification: starting projects, selecting features, planning, testing, compliance, and more

5.0 von 5 Sternen Prima grundlegende Erklärungsdetails 24. Dezember 2013
Format:Taschenbuch|Verifizierter Kauf
S34: "A service is an immutable encapsulation of some atomic behaviour of a device" ist eine super Erklärung, was man sich unter Service vorstellen soll. Dieser Satz wird aber fein säuberlich erklärt.
Besonders gut fand ich einige Hintergrunddetails wie und wieso etwas definiert wurde und das hilft fürs Gesamtverständnis.

5.0 von 5 Sternen Excellent, just get it 3. Januar 2014

For most fast-moving technology, the latest facts will not be in a printed book. On the other hand, the "grazing method" of learning new tech from the web often overlooks important first principles that end up biting you as a developer. The author has struck an excellent balance between explaining "what" and "why". Perhaps even more significantly, he interjects suggestions that are very, very helpful for an implementation-focused reader. BTLE is very different from classic BT from an implementer's perspective and this book is a superb way to jump-start yourself.

5.0 von 5 Sternen AN INDISPENSABLE COMPANION!!! 21. November 2012
Von COSMIC TRAVELER - Veröffentlicht auf
Are you an engineer, application developer, designer or marketing specialist, who is thinking about developing a product that incorporates Bluetooth low energy? If you are, then this book is for you! Author Robin Heydon, has done an outstanding job of writing a book that is a complete developer's handbook to how Bluetooth low energy technology came about, why it was designed, the way it was designed and how it works.

Author Heydon, begins with a brief introduction to Bluetooth low energy, and discusses its design goals. Then, the author discusses the foundations upon which the low energy architecture was designed. Next, he introduces the main system architecture fir low energy, from the controller, through the host, and up to the applications. The author also describes the new usage models that the low energy technology enables. He continues by showing you how devices communicate wirelessly with one another. Next, he highlights the Direct Test Mode and its role in performing low-cost, tome-efficient testing of the radio. The author also introduces the lowest layers of protocol that describe packets, advertising, and how to create a connection. He continues by describing the interface that hosts can use to talk with a controller and get it to do useful things. Then, the author describes the multiplexing layer. Next, he explains how a stateless protocol can be used to obtain the state of a device efficiently. The author also discusses the main body of the protocol that is used to provide security services. He continues by tying all of the pieces of the puzzle together into a high level abstraction that application writers can use. Next, he shows you how an application can use Bluetooth low energy to interact with peripherals. The author also explains how a peripheral can be designed to make the best use of the Bluetooth low energy technology. Finally, he explains how to qualify a design so that it can be sold or distributed.

This most excellent book covers the details of how the complete system works, from the physical radio waves up to the discovery of, connection with, and interface provided by that device. Perhaps more importantly, this great book provides the background of why Bluetooth low energy was designed; the design tools it tried to achieve; and, how you can take something that radically changes the way you can think of wireless technology and implement it in everything else.

5.0 von 5 Sternen The best available BTLE resource 13. April 2014
Von Garth Snyder - Veröffentlicht auf
Format:Kindle Edition
This book really stands in a class by itself. If you're implementing a BTLE device or even just trying to understand a cell phone's BTLE API, this is the book to get.

I particularly appreciate the extensive discussions of why certain aspects of the system have ended up the way they are. In many cases, there are power-efficiency motivations that make perfect sense once you understand their implications. If you don't know about these design motivations (i.e., you don't read this book), those aspects of BTLE will just seem weird. Other aspects of BTLE are inherited from previous versions of Bluetooth, so their oddity at least has some context. There again, it's good to know why.

That said, this book isn't perfect. At heart, BTLE is relatively SIMPLE. Unfortunately, the standard and the wretched terminology it uses do everything possible to obscure this fact. While this book does help to shed some light on the overall organization of the standard, it doesn't stray too far from the standard's conceptual model. That's good in that you'll end up well prepared to read the standard itself and all the other writings about BTLE. But it's also a bit disappointing in that once you break through to the other side of confusion, you'll realize that the journey probably didn't have to be so arduous.
4.0 von 5 Sternen Don't buy this book unless you have full knowledge of bluetooth 22. Juni 2014

I like this book because it is written for developers who would like to take bluetooth tech and capitalize from it. One thing I don't like is this book maybe difficult to understand if your are new to bluetooth tech and have no background in computer engineering.

-if your a new student to bluetooth
I don't recommend this book for you
because it's discusses a lot of advanced

-author explains subjects throughly.
-book is small compact. Not a thick college
-affordable/reasonable price

I rate this book at 4 stars.

any questions simply reply below!

Thanks a ton to Robin for writing this up in such a clear way.
The book does not assume any/much understanding of the basics and tells the whole story. A must for anybody looking to understand the BLE. Definitely this book is the starting point and then the BLE specs from the SIG.
The other good thing is that its coming from somebody who is an authority on the subject so you know what you are reading is correct for sure.
Again, Robin - thank you.
