CHIP PSoC6 All Clusters Example

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

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

  • 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-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.

  • On the command line:

      $ cd ~/connectedhomeip
  $ 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.
