CHIP PSoC6 Lighting Example

An example showing the use of Matter on the Infineon CY8CKIT-062S2-43012 board.

Matter PSoC6 Lighting Example

Introduction

The PSoC6 lighting example provides a baseline demonstration of a Light control device, built using Matter and the Infineon Modustoolbox SDK. It can be controlled by Matter controller over Wi-Fi network.

The PSoC6 device can be commissioned over Bluetooth Low Energy where the device and the Matter controller will exchange security information with the Rendezvous procedure. Wi-Fi Network credentials are then provided to the PSoC6 device which will then join the network.

Building

Modustoolbox Software
Refer to integrations/docker/images/chip-build-infineon/Dockerfile or scripts/examples/gn_psoc6_example.sh for downloading the Software and related tools.
Install some additional tools (likely already present for Matter developers): $ sudo apt install gcc g++ clang ninja-build python python3-venv libssl-dev libavahi-client-dev libglib2.0-dev git cmake python3-pip
Supported hardware: CY8CKIT-062S2-43012

Build the example application:

  $ source scripts/activate.sh
  $ scripts/build/build_examples.py --no-log-timestamps --target 'infineon-psoc6-light' build

To delete generated executable, libraries and object files use:
```
  $ cd ~/connectedhomeip
  $ rm -rf out/
```

Flashing the Application

Put CY8CKIT-062S2-43012 board on KitProg3 CMSIS-DAP Mode by pressing the MODE SELECT button. KITPROG3 STATUS LED is ON confirms board is in proper mode.

On the command line:

  $ cd ~/connectedhomeip
  $ python3 out/infineon-psoc6-light/chip-psoc6-lighting-example.flash.py

Commissioning and cluster control

Commissioning can be carried out using BLE.

Setting up Chip tool

Once PSoC6 is up and running, we need to set up chip-tool on Raspberry Pi 4 to perform commissioning and cluster control.

Set up python controller.

   $ cd {path-to-connectedhomeip}
   $ ./scripts/examples/gn_build_example.sh examples/chip-tool out/debug

Execute the controller.
```
   $ ./out/debug/chip-tool
```

Commissioning over BLE

Run the built executable and pass it the discriminator and pairing code of the remote device, as well as the network credentials to use.

     $ ./out/debug/chip-tool pairing ble-wifi 1234 ${SSID} ${PASSWORD} 20202021 3840

     Parameters:
     1. Discriminator: 3840
     2. Setup-pin-code: 20202021
     3. Node ID: 1234 (you can assign any node id)
     4. SSID : Wi-Fi SSID
     5. PASSWORD : Wi-Fi Password

Notes

Raspberry Pi 4 BLE connection issues can be avoided by running the following commands. These power cycle the BlueTooth hardware and disable BR/EDR mode.

      $ sudo btmgmt -i hci0 power off
      $ sudo btmgmt -i hci0 bredr off
      $ sudo btmgmt -i hci0 power on

Cluster control

After successful commissioning, use the OnOff cluster command to toggle device between On or Off states.
$ ./out/debug/chip-tool onoff on 1234 1
$ ./out/debug/chip-tool onoff off 1234 1
Cluster OnOff can also be done using the USER_BTN1 button on the board. This button is configured with APP_LIGHT_BUTTON in include/AppConfig.h. Press USER_BTN1 on the board to toggle between Light ON and OFF states. Light ON and OFF can be observed with ‘LED9’ on the board. This LED is configured with LIGHT_LED in include/AppConfig.h.

Factory Reset

Commissioned Wi-Fi Credentials can be cleared by pressing USER_BTN2 button on the board. All the data configured on the device during the initial commissioning will be deleted and device will be ready for commissioning again.
Pressing the button again within 5 seconds will cancel the factory reset of the board.
