Quick-Start Guides for Matter over Thread and Matter over Wi-Fi#

Overview#

The procedures here describe how to make a simple network of a light, a switch, and a Matter hub, and to use the switch to control the light. First, set up your hardware and software as described below. Then you will follow a step by step procedure to:

  • Create a Matter hub on a Raspberry Pi.

  • Compile and load a light and a switch example application onto two Silicon Labs development boards to make light and switch Matter Accessory Devices (MADs).

  • Create a Matter network with the MADs and the Matter hub.

  • Test the light through the Matter hub.

  • Bind the switch MAD to the light MAD, so that the switch can control the light.

Initial Setup#

Both the Matter over Wi-Fi and Matter over Thread demos require that you have set up a simple development environment with Simplicity Studio, two EFR32MG24-based development boards, and a Raspberry Pi used as a Matter hub. The following requirements are common to both demos. The Thread demo also requires a radio co-processor (RCP) as part of the Matter Hub. The requirements for this are provided in the introduction to the Thread demo.

Hardware Requirements#

Matter Hub#

  • 1 Raspberry Pi 4B

  • 1x high speed, 64 GB SD card

Matter Devices#

Matter Over Wi-Fi Accessory Device Requirements for NCP Mode#

The Silicon Labs Matter over Wi-Fi NCP mode demo and development requires two boards: the Silicon Labs EFR32 Radio board to run the Matter code and either the RS9116, SiWx917, or WF200 to run the Wi-Fi protocol stack.

The following boards are supported for the Matter over Wi-Fi demos and development:

  • MG24 Boards:

  • Wi-Fi NCP Dev Kits & boards

    • RS9116

    • SiWx917 NCP

      • SiWx917 NCP Mode / Wi-Fi Expansion Board / 2.4GHz

        • BRD8045A (B0 Expansion v2.0)

    • WF200

      • WF200 / Single Band Wi-Fi Expansion Board / 2.4GHz

    • Interconnect board (included in the Wi-Fi kits)

    • SPI Cable (included in the RS9116 kit)

    • Jumper Cables (included in the RS9116 kit)

Note: For more information, refer to Hardware Requirements.

Matter Over Wi-Fi Accessory Device Requirements for SoC Mode#

The Silicon Labs Matter over Wi-Fi demo and development for SoC mode requires the SiWx917 SoC board that supports Matter over Wi-Fi in a single-chip package. The integrated MCU is dedicated for peripheral and application-related processing (Matter), while the ThreadArch® runs the wireless and networking protocol stacks.

Pre-built images for the SiWx917 connectivity firmware are available as per the instructions on the Matter Artifacts page. The following boards are supported for the Matter over Wi-Fi demos and development:

  • Wi-Fi SoC Boards:

    • SiWx917 / BRD4002A / Wireless Starter Kit

    • SiWx917 Soc Mode

      • SiWx917 SoC / Common Flash Radio Board / 2.4GHz

        • BRD4338A - B0 common flash v2.0

Software Requirements#

Simplicity Studio 5: Download and install Simplicity Studio 5 for your operating system from the Silicon LabsSimplicity Studio page. While the installation process is easy to follow, instructions are provided in the Simplicity Studio v5 Getting Started section.

Ozone - The J-Link Debugger: Ozone is a full-featured graphical debugger for embedded applications. With Ozone, it is possible to debug any embedded application on C/C++ source and assembly level.

Simplicity Commander: Simplicity Commander is a utility that provides GUI and command line access to the debug features of an EFM32 device. It allows you to flash firmware, update the kit firmware, and lock or unlock debug access.

Tera Term: Tera Term is the terminal emulator for Microsoft Windows that supports serial port, telnet, and SSH connections.

Silicon Labs Matter GSDK Extension: Once Simplicity Studio 5 is installed, you will be prompted to install the Gecko SDK Suite (GSDK). Here you should also install the Matter Enablement Package by making sure the extension is checked, as shown.

Installing the Matter Extension

Installation of Wi-Fi SDK and Wiseconnect Packages The following packages will be installed during the installation of Simplicity Studio, Refer to Package Installation

Matter Hub Raspberry Pi Image: A copy of the pre-built image from the Silicon Labs web services can be downloaded in this zipfile. Note this is a large file and will take some time to download.

Note: The Matter hub for Matter over Thread requires an additional device, a radio co-processor. See the introduction to the Matter over Thread demo for more information.

Matter Bootloader Image: The EFR32MG24 devices must be programmed with a bootloader. Obtain those here: Silicon Labs Matter Artifacts.

SSH Client: Managing the Matter hub often requires connecting to it remotely. An SSH client is needed to follow the step-by-step example in this document (PuTTY is used). Install software such as PuTTY, Terminal, or a similar application for access to the Raspberry Pi-based Matter hub.

SD Card-Flashing Software: Many different applications can be used to prepare an SD card for the Raspberry Pi, such as the Raspberry Pi Imager, balenaEtcher, and Rufus. The step-by-step example in this document uses the Raspberry Pi Imager.

Visual Studio Code Development#

In addition to creating and building your Matter project within Simplicity Studio, Silicon Labs also provides Visual Studio Code (VSCode) IDE integration. Matter projects support VSCode integration with the exception of Matter Solutions projects.

For more information on development within Visual Studio Code, please visit Visual Studio Code Enablement.

Next Steps#

Now that you have your environment, you can create a Matter over Wi-Fi network or a Matter over Thread network.
