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 6. Bluetooth Mesh Technology

In the age of electronics, the Internet emerged as a global system to connect every computer system around the globe. It revolutionized communication processes and forced us all to move from circuit-switch networks to packet-switch networks. The basic definition of the Internet states that it is a network of networks, where each node follows the TCP/IP model to communicate with another node. The idea of connecting everything is appealing, but in which topology type should we do it? Should it be bus, star, ring, daisy chain, or point-to-point?

Let's discuss this problem on a smaller scale. A rather private version of the Internet is called an intranet, which is a private network accessible to only a group of people. It can be an office network, hospital network, school network, and so on. If we have 10 computers in an intranet, there should be a way to connect those computers so that they can communicate with each other. Generally, a WLAN is connected in...
