Matter Wi-Fi Direct Internet Connectivity

• Direct Internet Connectivity (DIC) is a silabs only feature to connect matter devices to proprietary cloud solutions(AWS,GCP,APPLE …) directly. As such, a Matter Wi-Fi device must support connecting locally on the Matter Fabric, via IPv6, and connecting to the Internet via IPv4.

• Matter devices can be controlled by chip-tool or controller and the respective status of the attribute modified will be published to the cloud.

• Remote user can install the cloud specific application to get the notification on the attribute status.

Message Queuing Telemetry Transport (MQTT)

• MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. Refer https://mqtt.org/ for more details

Configuration of MQTT server

To set up and configure AWS or Mosquitto for DIC support please see the following documentation:

• AWS installation

• Mosquitto installation

Remote User Setup (MQTT Explorer)

• A remote user is used to check the state of device. In this context MQTT explorer is used as a remote user.

• MQTT explorer setup and configuration

DUT Setup

• Software and Hardware prerequisites for working with Silicon Labs Matter.

1. Matter Hardware Requirements

2. Matter Software Requirements

3. Use the build command for DIC instead of Normal build command which one present in SW_SETUP.md Don’t use normal build comands

• Build for DIC

End-to-End Test of DIC Light Application

• Sharing status of device to cloud

  • End-to-end command to be executed from chip-tool, refer Running the Matter Demo on EFR32 hosts

  • Below is the application specific attribute/s information or state shared to the cloud through Direct Internet Connectivity Solution

    • For Lighting App, On/Off Attributes

    • For Lock App, lock/unlock Attributes

    • For On/off Plug App, On/Off Attributes

  • Application status would be updated on the mqtt_explorer UI, as shown in below image.

• Control of the device through cloud interface

  • Make sure matter device is up and commissioned successfully, refer Running the Matter Demo on EFR32 hosts

  • For Controlling the device, set topic name and the commands to be executed in the mqtt_explorer for below applications.

    • Lighting App

      • Topic: command

      • Commands:

        • toggle

        • on

        • off

    • Onoff-plug App

      • Topic: command

      • Commands:

        • toggle

        • on

        • off

    • Lock App

      • Topic: command

      • Commands:

        • lock

        • unlock

  • Then click publish button to execute the command.

• Download AWS OTA Image through cloud interface

  • Make sure matter device is up and commissioned successfully, refer Running the Matter Demo on EFR32 hosts

  • Make sure device is connected to MQTT Server successfully.

  • Then Create a AWS OTA Job in the AWS Website, refer How to create AWS OTA JOB

  • Trigger OTA Command through MQTT Explorer like below.

  • Then click publish button to execute the AWS OTA command.
