Bluetooth Low Energy, a successor to the Classic Bluetooth, is a young technology with huge adoption rate and big market. The technology made itself visible in mid 2010; when big manufacturers like Apple launched their products in the market with Bluetooth Low Energy support. Not only this, but Bluetooth version 4.0 took care of the biggest dilemma of the previous decade. It now consumed less power as compare to its predecessor. Bluetooth Special Interest Group (SIG), the developers and maintainers of Bluetooth technology, made sure that the technology matched the trend of the market and helped to spread itself in the Internet of Things (IoT). Chapter 1, BLE and the Internet of Things, described the context of Bluetooth Low Energy in the world of the Internet of Things and how it got popular amongst the manufacturer as a cheap short-distance communication technology.

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.
