Building Wireless Sensor Networks with OpenThread: Developing CoAP applications for Thread networks with Zephyr

This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it.

You’ll acquire knowledge on:
• The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4.
• Network simulation with the OpenThread Network Simulator.
• Connecting a Thread network to a non-Thread network using a Thread Border Router.
• The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network.
• The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses.
• The process of joining a Thread network using network commissioning.
• CoAP servers and clients and their OpenThread API.
• Service registration and discovery.
• Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates.
• Investigating and optimizing a Thread device’s power consumption.

Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.
