Starting with an introduction to iBeacon, you will learn all about simple beacon detection. You will learn how to use Apple’s CoreBluetooth, CoreLocation, and PassKit libraries, and how to broadcast different values through the power of transmission power. You will learn how to allow your apps to detect beacons, determine their distance, and even turn your iPhone or iPad into a Bluetooth iBeacon by building a simple treasure-hunting app. We will also be discussing two of the most popular beacons (Estimote and ROXIMITY). Don’t worry if you haven’t got any beacons; this book includes a companion app that lets your Mac or MacBook act as a beacon to allow you to jump straight into learning this incredible technology. By the end of this book, you will have learned how to build apps that interact with the world around them using Bluetooth beacons.
