This book is where your adventures with Bluetooth LE begin. You'll start
your journey by getting familiar with your hardware options: Arduino,
BLE modules, computers (including Raspberry Pi!), and mobile phones.
From there, you'll write code and wire circuits to connect off-the-shelf
sensors, and even go all the way to writing your own Bluetooth Services.
Along the way you'll look at lightbulbs, locks, and Apple's iBeacon
technology, as well as get an understanding of Bluetooth security--?both
how to beat other people's security, and how to make your hardware
secure.
