This section reviews the steps for running an example lighting-app for Matter over Thread. See this file for an introduction to the Matter over Thread setup.
At a high level, we will walk through starting a Thread network, commissioning a new device to the Thread network using Bluetooth LE, and finally sending a basic OnOff command to the end device.
Before beginning your Matter project, you should have the software and systems described in Matter Hardware and Software Prerequisites.
The Matter Hub consists of the OTBR and the ChipTool running on a Raspberry Pi. Silicon Labs has developed a Raspberry Pi image that can be downloaded and flashed onto an SD Card, which is then inserted into the Raspberry Pi.
The Matter Controller sends IPv6 packets to the OTBR, which converts the IPv6 packets into Thread packets. The Thread packets are then routed to the Silicon Labs end device.
See How to use Matter Hub (Raspberry Pi) Image for setup instructions.
The Radio Co-Processor (RCP) is a Thread device that connects to the Raspberry Pi via USB. To flash the RCP, connect it to your laptop via USB. Thereafter, it should be connected to the Raspberry Pi via USB as well. Prebuilt RCP images are available for the demo
Information on flashing and optionally building the RCP is located here: How To Build and Flash the RCP
The Matter Accessory Device (MAD) is the actual Matter device that will be commissioned onto the Matter network and controlled using the ChipTool. Prebuilt MAD images are available for the demo.
Information on flashing and optionally building the Matter Accessory device is located here: How To Build and Flash the Matter Accessory Device
Once the Matter Accessory device has been flashed onto your hardware you can commission it from the Matter Hub using the commands provided in the Raspberry Pi image:
| Command | Usage |
|---|---|
| mattertool startThread | Starts the thread network on the OTBR |
| mattertool bleThread | Starts commissioning of a MAD using ChipTool |
| mattertool on | Sends an on command to the MAD using ChipTool |
| mattertool off | Sends an off command to the MAD using ChipTool |
