Introduction

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.

Building

• 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/gn_genio_example.sh ./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/activate.sh`
    `$ 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

  third_party/mt793x_sdk/filogic/flash_tool

• 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]](https://github.com/project-chip/connectedhomeip/blob/master/docs/development_controllers/chip-tool/chip_tool_guide.md)

  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>
  

Notes

• 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
