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

Biographie de l'auteur

Robin Heydon began working on the Wibree project in 2007–a project that evolved into the Bluetooth low energy specification covered here. Heydon cochaired the original specification group and drove the spec through to publication. Heydon has worked in wireless communications since 2000, first as a firmware engineer and now as a full-time standards architect. He has contributed to fixing and improving every version of the Bluetooth specification. In 2010, in recognition of his work, he was honored as one of only a small group of members of the Bluetooth SIG Hall of Fame.

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 étoiles sur 5 The best available BTLE resource 13 avril 2014
Par Garth Snyder - Publié sur Amazon.com
Format:Format Kindle
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.

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.

1.0 étoiles sur 5 It's not much help. Save your money. 18 octobre 2015

So you're implementing a BS (BLE) design on a product, you've selected an MCU chip such as nRF51, you're a developer and you want "The Developers Guide", what K&R was to C, you are looking for the equivalent for BLE (or BS as it's honestly now been renamed). Well this book isn't it. I can't understand the many high ratings.

With this book you won't see the woods for the trees. A collection of spurious and poorly organized definitions, concepts and content, much of it redundant, useless or out of place, and you'll be 130 to 230 pages into it without finding out anything helpful. A guide it is not. It's a collection of subheadings and sections, poorly thought out and seemingly mostly existing just to fill in space to pad out the book. You'll find much better guides on Wikipedia and the official BLE site.

4.0 étoiles sur 5 Don't buy this book unless you have full knowledge of bluetooth 22 juin 2014

Format:Broché|Achat vérifié
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.

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

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

I rate this book at 4 stars.
