BeagleBone Black Cookbook

Overview of this book

There are many single-board controllers and computers such as Arduino, Udoo, or Raspberry Pi, which can be used to create electronic prototypes on circuit boards. However, when it comes to creating more advanced projects, BeagleBone Black provides a sophisticated alternative. Mastering the BeagleBone Black enables you to combine it with sensors and LEDs, add buttons, and marry it to a variety of add-on boards. You can transform this tiny device into the brain for an embedded application or an endless variety of electronic inventions and prototypes. With dozens of how-tos, this book kicks off with the basic steps for setting up and running the BeagleBone Black for the first time, from connecting the necessary hardware and using the command line with Linux commands to installing new software and controlling your system remotely. Following these recipes, more advanced examples take you through scripting, debugging, and working with software source files, eventually working with the Linux kernel. Subsequently, you will learn how to exploit the board's real-time functions. We will then discover exciting methods for using sound and video with the system before marching forward into an exploration of recipes for building Internet of Things projects. Finally, the book finishes with a dramatic arc upward into outer space, when you explore ways to build projects for tracking and monitoring satellites.

Location-based recipes – Bluetooth LE and Beacons


In the past, you may have had the opportunity to use Bluetooth devices in your projects. However, in all probability, that would have been an earlier version of BT, now commonly referred to as "classic" Bluetooth. Before we jump into an actual recipe on how to use these small radio devices, we should take a look at some of the significant differences between the classic version of Bluetooth and the Bluetooth Low Energy (BLE) spec because they are very different animals. Although they are both available as part of the 4.0 spec, we will work only with the BLE piece for our recipe.

Classic Bluetooth

With the classic version of the stack, one device basically connects to another device, data is exchanged serially, and the data does not persist. For example, when you set up a BT headset, the audio comes piping into your ears, and the data goes on after the throughput. Furthermore, the connection does not reveal or show anything about what's happening...
