Commissioning with the Simplicity Connect App#

The mobile phone running Simplicity Connect must be connected to the same Wi-Fi network as the Matter Hub. Open a terminal in the Matter hub and start by running this command to get the dataset.

$ mattertool startThread

  • Copy the generated dataset (refer to the image above for the dataset). This dataset will be used on Android and iOS devices during the commissioning of Matter devices.

  • At this point, the Matter device is already on the network and requires network credentials for Thread.

  • After flash, you will see the QR code on the device.

Taking it Further#

After successfully running the Matter Lighting app to the ecosystem, the next step is to create, build, and flash a Matter sample project from Simplicity Studio.

Step 1: Create a Matter Sample Project#

  1. Open Simplicity Studio and select Create New Project.

  2. Filter for Matter and select the Matter - SoC Lighting over Thread with external Bootloader sample application and select Create.

  3. Click Finish. Simplicity Studio will create a new Solution called MatterLightOverWiFiSolution with the MatterLightOverThreadSolution project inside.

  4. Open the project.
