In this chapter, we were introduced to the Raspberry Pi and discussed how the Raspberry Pi 3 Model B is a great choice for implementing IoT projects. The second part of the chapter was learning how to install Raspbian, a Debian-based Linux operating system, on the Raspberry Pi 3 using NOOBS. Once it was all set up, we updated the software and installed required utilities (such as Node.js and Bluez) on the Raspberry Pi and got it ready for development. After installing the software, we studied how to deploy the Bluetooth SIG's Bluetooth gateway project and got it running with a web server. The Bluetooth gateway communicates with the web server, and we learned how the communication happens between the gateway and the web server. The chapter also extensively referenced Node.js code, as it was our development platform for both the Bluetooth gateway and the web...

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.
