Matter P6 Lock Example

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

Matter P6 Lock Example

Introduction

The P6 lock example provides a demonstration of a door lock control device, built using Matter and the Infineon Modustoolbox SDK. It can be controlled by a Matter controller over Wi-Fi network.

The P6 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 P6 device which will then join the network.

Building

Modustoolbox Software
Refer to integrations/docker/images/chip-build-infineon/Dockerfile or scripts/examples/gn_p6_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-p6-lock' 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-p6-lock/chip-p6-lock-example.flash.py

Commissioning and cluster control

Commissioning can be carried out using BLE.

Setting up Chip tool

Once P6 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_LOCK_BUTTON in include/AppConfig.h. Press USER_BTN1 on the board to toggle between lock and unlock states. The Lock/Unlock status of door can be observed with ‘LED9’ on the board. This LED is configured with LOCK_STATE_LED in include/AppConfig.h.
