SDK modification

Matter can be used either from

When using github repositories, follow this guide to setup up a Matter development environment

In this tutorial, we will only focus on the SimplicityStudio window covering example

  1. Once you have created a MatterWindowCoverOverThread project in Simplicity Studio, modify the src/WindowAppImpl.cpp file

    This modification allows to reach better consumption figures in both SED and SSED mode. By default, application event queue is polled every 10 ms. To reduce consumption, change the queue management from polling to blocking:

    -    BaseType_t received = xQueueReceive(mQueue, &event, pdMS_TO_TICKS(10));
+    BaseType_t received = xQueueReceive(mQueue, &event, portMAX_DELAY);

  2. Add the Sleepy End Device component in your project. For all the conflicts raised, replace the current component by the Sleepy End device version.

  1. Modify the InitOpenThread() function of matter_x.x.x/examples/platform/silabs/efr32/matter_config.cpp file

    This modification will enable Synchronized Sleepy End Device type at Thread level.

       #if CHIP_DEVICE_CONFIG_THREAD_FTD
 ReturnErrorOnFailure(ConnectivityMgr().SetThreadDeviceType(ConnectivityManager::kThreadDeviceType_Router));
   #else // CHIP_DEVICE_CONFIG_THREAD_FTD
   #if CHIP_DEVICE_CONFIG_ENABLE_SED
   #if CHIP_DEVICE_CONFIG_THREAD_SSED
 ReturnErrorOnFailure(ConnectivityMgr().SetThreadDeviceType(ConnectivityManager::kThreadDeviceType_SynchronizedSleepyEndDevice));
   #else
 ReturnErrorOnFailure(ConnectivityMgr().SetThreadDeviceType(ConnectivityManager::kThreadDeviceType_SleepyEndDevice));
   #endif
   #else  // CHIP_DEVICE_CONFIG_ENABLE_SED
 ReturnErrorOnFailure(ConnectivityMgr().SetThreadDeviceType(ConnectivityManager::kThreadDeviceType_MinimalEndDevice));
   #endif // CHIP_DEVICE_CONFIG_ENABLE_SED
   #endif // CHIP_DEVICE_CONFIG_THREAD_FTD

  2. Add the definition of CHIP_DEVICE_CONFIG_THREAD_SSED macro to your project
