Matter PSoC™ 6 door lock example

This code example makes use of Matter on an Infineon PSoC™ 6 board to demonstrate its functionality as a Wi-Fi door lock device.

Requirements

• ModusToolbox™ software v3.2 or later (tested with v3.2)
• PSoC™ 6 board with 2 user buttons, 2 MB of Flash, and two user LEDs
• PSoC™ 6 board support package (BSP) minimum required version: 4.0.0
• Programming language: C/C++
• Associated parts: All PSoC™ 6 MCU(https://www.infineon.com/PSoC6) parts

Supported toolchains (make variable 'TOOLCHAIN')

• GNU Arm® embedded compiler v11.3.1 (GCC_ARM) - Default value of TOOLCHAIN

Supported kits (make variable 'TARGET')

CY8CKIT-062S2-43012

Software setup

• ModusToolbox™ tools package

Hardware setup

• The board should be in KITPROG3 mode.
• Check for the LED in the ON state (not blinking)
• Connect the USB device to the host.

Using the CE

The Project can be created using any one of the following ways:

Using Eclipse IDE for ModusToolbox™ Follow the steps given here:

1. Quick Panel --> New Application

2. In the Project Creator Tool, choose a kit that is supported by the code example Project Creator --> Board Support Package (BSP) dialog.

3. Click on the check box containing the example under Select Application

4. Click Create.

Using the CLI

1. Open the Project Creator from the Windows Start menu

2. You could also choose {ModusToolbox™ software install directory}/tools_{version}/project-creator/project-creator.exe.

3. Choose the required BSP, and click Next.

4. Select the appropriate IDE from the Target IDE drop-down menu under the Select Application

5. Click Create

6. Export the application to the desired IDE. Refer to the ModusToolbox™ tools package user guide, "Using applications with third-party tools" chapter for details.

Setting up chip-tool

Once the application is running, 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 Bluetooth® LE

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 Bluetooth® LE 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 Lock Unlock cluster command to toggle device between Lock or Unlock states.

  $ ./out/debug/chip-tool doorlock lock-door 1234 1 --timedInteractionTimeoutMs 100

  $ ./out/debug/chip-tool doorlock unlock-door 1234 1 --timedInteractionTimeoutMs 100

• Cluster Lock Unlock 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 the door lock can be observed with 'Red LED' on the board. This LED is configured with LOCK_STATE_LED in include/AppConfig.h.

OTA software update

• Over The Air (OTA) support can be included in the Wi-Fi door lock application by following either of these routes:

Using the Infineon OTA middleware library

The OTA library provides support for Over-The-Air update of the application code running on an Infineon device. The ModusToolbox OTA code examples import the ota-update library automatically. This application is built in ModusToolbox™ software, integrated with the OTA library.

For more information refer - [OTA_using_ModusToolbox] https://github.com/Infineon/ota-update

Using MATTER (project-chip repository)

Matter provides a system for OTA to be run as a provider requestor.

PSoC™ 6 Deep Sleep

• PSoC™ 6 can put to Deep Sleep for longer period of time by suspending Network stack and enabling WLAN Offload features using LPA.

• Refer to LPA Quick Start Guide - Code Snippets for more information on APIs to be used.

• Network stack suspend/resume logic should be added after Wi-Fi Connection is successfully established. This can be done in AppTask::Init function after starting DnssdServer.

    if (event->InternetConnectivityChange.IPv4 == kConnectivity_Established ||
        event->InternetConnectivityChange.IPv6 == kConnectivity_Established)
    {
        chip::app::DnssdServer::Instance().StartServer();
        //Create new task which calls wait_net_suspend API implemented in LPA
    }

• Configure Various WLAN offloads using the ModusToolbox™ Device Configurator. Refer to LPA Quick Start Guide
