Introduction

This is the chapter web page to support the content in Chapter 12 of the book: Exploring BeagleBone – Tools and Techniques for Building with Embedded Linux. The summary introduction to the chapter is as follows:

This chapter describes how a Beagle board can be configured to wirelessly communicate to the internet, and to wirelessly interface to devices and sensors using different communication standards. The chapter begins with a description of how Bluetooth communications can be used to develop a wireless remote-control framework using mobile apps. Next, a description is provided on how the board can be configured to connect to the internet using USB Wi-Fi adapters. The discussion on Wi-Fi continues with a description of how the low-cost NodeMCU (ESP8266) Wi-Fi microcontroller can be used to build a local network of wireless things, which can communicate sensor values to the Beagle board and to an IoT PaaS. The ZigBee protocol is then used to build peer-to-peer wireless networks that use the popular XBee ZigBee devices. Finally, NFC/RFID is used to build a simple security access control system. By the end of this chapter you should be able to choose an appropriate wireless communication standard to suit your needs and you should be able to build sophisticated wireless IoT applications.

Learning Outcomes

After completing this chapter, you should be able to:

  • Choose an appropriate wireless communication protocol and associated hardware for your projects.
  • Configure a USB Bluetooth adapter for your Beagle board and connect to it from a mobile device for the purpose of building a basic remote-control application.
  • Install a USB Wi-Fi adapter on a Beagle board and configure the board to connect to a secured Wi-Fi network.
  • Use the NodeMCU device to build a distributed wireless network of things that is controlled by a Beagle board.
  • Build on skills developed in Chapter 11 to create IoT devices that can be wireless.
  • Use the ZigBee protocol with XBee adapters in AT mode to establish a wireless serial data link.
  • Investigate ZigBee using XBee devices that are configured in API mode, which allows for the use of advanced ZigBee features, such as mesh networking.
  • Use NFC/RFID devices to build a basic access control system.
