#Matter Genio Lighting Example

An example showing the use of Matter on the MediaTek Genio MT793X.


The Genio (MT793X) lighting example provides a baseline demonstration of a Light control device, built using Matter and the MediaTek Genio SDK. It can be controlled by a Chip controller over Wi-Fi network.

The Genio device can be commissioned over Bluetooth Low Energy where the device and the Chip controller will exchange security information with the Rendez-vous procedure. Network credentials are then provided to the Genio device which will then join the network.

The lighting example is intended to serve both as a means to explore the workings of Matter as well as a template for creating real products based on the MediaTek platform.


  • Following the Linux related descriptions in Build Matter to prepare the build environment.

  • Supported hardware:

    Genio 130A (MT7931) board:

    • EK-AI7931LD KIT
  • Build the example application:

      `cd ~/connectedhomeip`
      `./scripts/examples/ ./examples/lighting-app/genio` `./out/lighting-app`
  • To delete generated executable, libraries and object files use:

      `$ cd ~/connectedhomeip`
      `$ rm -rf ./out/`

    OR use GN/Ninja directly

      `$ cd ~/connectedhomeip/examples/lighting-app/genio`
      `$ git submodule update --init`
      `$ source third_party/connectedhomeip/scripts/`
      `$ gn gen out/debug`
      `$ ninja -C out/debug`
  • To delete generated executable, libraries and object files use:

      `$ cd ~/connectedhomeip/examples/lighting-app/genio`
      `$ rm -rf out/`

Flashing the Application

  • Copy the GUI based Flash Tool. from the Linux Host that the example was build to a Windows PC.

    Flash Tool can be found in this source tree under this directory


  • On the Windows PC, run the Flash Tool

    1. Select the scatter.ini file in the ./out/lighting-app directory.
    2. Follow the instruction that comes with EK-AI7931LD KIT to switch the kit to download mode.
    3. Click Download on FLASH TOOL.

Running the Complete Example

  • You can provision and control the Chip device using the python controller, Chip tool standalone, Android or iOS app

    [CHIP Tool]](

    Here is an example with the CHIP Tool controller:

      chiptool- pairing ble-wifi 1234 my-ap myappassword 20202021 3840
      chiptool onoff on 1 1
      chiptool onoff off 1 1
  • You can test the LED by light command as shown below

      > light
        help            Usage: light <subcommand>
        onoff           Usage: light onoff <subcommand>
        color           Usage: light color <r:0~255> <g:0~255> <b:0~255>
        level           Usage: light level <level:0~100>


  • Depending on your network settings your router might not provide native ipv6 addresses to your devices (Border router / PC). If this is the case, you need to add a static ipv6 addresses on both device and then an ipv6 route to the border router on your PC
