CHIP PSoC6 All Clusters Example

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

Matter PSoC6 All Clusters Example

Introduction

The PSoC6 clusters example provides a baseline demonstration of a Cluster 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

Download and install Modustoolbox Software v3.2
Refer to integrations/docker/images/stage-2/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-all-clusters' 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. (Modustoolbox Software needs to be installed)

On the command line:

  $ cd ~/connectedhomeip
  $ export CY_TOOLS_PATHS=<Modustoolbox install location>/tools_3.2
  $ python3 out/infineon-psoc6-all-clusters/chip-psoc6-clusters-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

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.
