Overview of this book

Bluetooth Low Energy (BLE) is a Wireless Personal Area network technology aimed at novel applications for smart devices. High-tech BLE profiles and services are being increasingly used by application developers and hardware enthusiasts to allow devices to interact with the surrounding world. This book will focus on a technical introduction to BLE and how it is reshaping small-distance communication. We will start with IoT, where many technologies such as BLE, Zigbee, and IEEE 802.15.4 Mesh will be introduced. The book will present BLE from an engineering perspective, from which the protocol stack, architecture, and layers are discussed. You will learn to implement customized projects for Peripheral/Central communication, BLE Beacons, indoor navigation using triangulation, and the Internet gateway for Bluetooth Low Energy Personal Network, all using various code samples and APIs on Android, iOS, and the Web. Finally, the book will conclude with a glimpse into future technologies destined to be prominent in years to come.

Preface

Chapter 7. Implementing a Bluetooth Gateway Using the Raspberry Pi 3

We are on the verge of a technological boom, where the concept of smart homes will lead the way. If you analyze the history computer technology, you can define it in three periods: the era of personal computing, the era of cellular phone evolution, and the era of smart devices. While this chapter does not describe the ups and downs of each era, it is important to know that there was no gap between these periods. They came back to back, and companies that did not catch up were left behind. 

A notable example from the first period is IBM: a company that stood in competition with Apple in the early era of computing now does not list itself among the major brands of personal computers. Nokia, a well-known name in cellular phone manufacturing, could not keep the pace with Apple and Samsung in the second era. It stuck with the Symbian OS when Apple was developing the state-of-the-art iOS and Samsung was working with Android. Nokia...
