Livre : Building Wireless Sensor Networks with OpenThread
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.
Nordic Semiconductor nRF52840 USB Dongle
The nRF52840 dongle is a small, low-cost USB dongle that supports Bluetooth 5.3, Bluetooth mesh, Thread, ZigBee, 802.15.4, ANT and 2.4 GHz proprietary protocols. The dongle is the perfect target hardware for use with nRF Connect for Desktop as it is low-cost but still support all the short range wireless standards used with Nordic devices.
The dongle has been designed to be used as a wireless HW device together with nRF Connect for Desktop. For other use cases please do note that there is no debug support on the dongle, only support for programming the device and communicating through USB.
It is supported by most of the nRF Connect for Desktop apps and will automatically be programmed if needed. In addition custom applications can be compiled and downloaded to the dongle. It has a user programmable RGB LED, a green LED, a user programmable button as well as 15 GPIO accessible from castellated solder points along the edge. Example applications are available in the nRF5 SDK under the board name PCA10059.
The nRF52840 dongle is supported by nRF Connect for Desktop as well as programming through nRFUtil.
