Matter Lock Application (rm_matter_app_port_w)

Application porting layer for the MATTER on RAFW. This module implements the Matter Interface.

Overview

Matter is a unified, open-source application-layer connectivity standard built to enable developers and device manufacturers to connect and build reliable, secure IoT products. For more information, see the Matter website.

This module provides the lock application porting Layer for Matter V1.3 on the Renesas RAFW devices.

Features

The Matter Wi-Fi Apps module has the following key features:

• Matter application porting layer for Renesas RAFW devices
• Pre-configured Matter Lock application supports commissioning and basic opertions with Matter server or Matter hub
• Reference for developing custom applications for Matter on Renesas RAFW devices

Configuration

Configurations for Matter > Matter app-port (rm_matter_app_port_w)

This module can be added to the Stacks tab via New Stack > Matter > Matter app-port (rm_matter_app_port_w).

Configuration	Options	Default	Description

Clock Configuration

This module has no required clock configurations, but the user must configure the clock for the Wi-Fi module. Recommended clock configuration for this module is 160 MHz.

Pin Configuration

This module does not use I/O pins.

Usage Notes

Refer to WIFI (rm_wifi) and Matter Interface.

• This module is not a standalone module - ensure that the Wi-Fi module APIs are invoked first to configure the RAFW module and use the Matter APIs.
• Sample applications are provided in the module to demonstrate the usage of Matter APIs, which can be used as a reference for developing custom applications.
• For developing custom applications, the user should provide the cluster specific implementation from Matter Website, and ZAP generated files for the clusters.

Limitations

Refer to WIFI (rm_wifi) and Matter Interface.

• Samples provided in the module are device applications. To check the functionality Matter application, the user must have a Matter server or Matter hub to connect to the Matter device.
• CHIPProjectConfig.h from the Matter application is generated seperately as rm_matter_wifi_cfg.h file by configuration from the e2studio, which is used to configure the Matter stack. The user should modify the configuration from e2studio to change the Matter stack configuration.
• Matter application's memory usage is differ per application. For the reference, memory usage of the sample Lock application is as follows:

	Total OS Heap	Minimum ever free bytes remaining	Available HEAP space for RAFW
Not Connected (Wi-Fi Only)	307200 bytes	175344 bytes	180720 bytes
Connected (Wi-Fi Only)	307200 bytes	169992 bytes	210928 bytes
Before Commissioning	276480 bytes	115864 bytes	161072 bytes
After Commissioning	276480 bytes	115864 bytes	123488 bytes
During Lock Control	276480 bytes	115864 bytes	123296 bytes

Examples

Basic Example

This is a basic example of minimal use of the rm-matter-wifi-apps in an application.

void matter_apps_basic_example (void)
{
   fsp_err_t err = FSP_SUCCESS;

   err = WIFI_On();
   assert(FSP_SUCCESS == err);
   err = MATTER_On();
   assert(FSP_SUCCESS == err);

   while(1)
   {
      vTaskDelay(200);
   }
}
