Features

This is the Silicon Labs Matter v2.1.1-1.1 release, which provides the functionality to build Matter applications in the Simplicity Studio environment. This release is intended for developers who wish to run a Matter Demo over Thread (15.4) or Wi-Fi, and also manually build examples through Simplicity Studio.

This release is certifiable to the Connectivity Standards Alliance (CSA)'s Matter 1.1 certification program (https://csa-iot.org/) for Thread (MG12, MG24).

Known Issues

General

  • The Matter device images require approximately 700k in flash space. As a result only a subset of EFR32MG12 and EFR32MG2x devices are supported. For a complete list of devices supported consult the documentation located at Matter Hardware Requirements.
  • When upgrading an existing Simplicity Studio project to the latest GSDK and Matter version, the project build should not be initiated until the old GSDK and Matter folders in the project view are replaced by the new ones (this takes approximately a minute).
  • For the BRD4319A board only the A00 revision is supported, other revisions do not have enough RAM to run Matter.
  • Matter SDK Issues (https://github.com/project-chip/connectedhomeip)
    • BLE Connection/Timeout error occurs occasionally during commissioning with the chip-tool running on Raspberry Pi or Linux (project-chip#16178). Running on these platforms requires an access point with both 2.4 GHz and 5 GHz capabilities. There is BLE-WiFi interference when connected over the 2.4 GHz channel. This is resolved by connecting the chip-tool device to a 5 GHz SSID and the end device to a 2.4 GHz SSID for the same Wi-Fi network.

Thread

  • Silicon Labs has provided a complete image file for the Raspberry Pi that can be flashed onto an SD card to create the "Matter Hub", which is a Raspberry Pi running Ubuntu and includes a pre-built version of the Open Thread Border Router (OTBR) and chip-tool. The image we have provided is quite large, ~6 GB. As a result it can take quite a while to download the .zip file and flash it onto an SD card. Depending on your connection the process could take up to half an hour. Regardless, the demo and development experiences using this pre-built image is a much faster process than building the Matter Hub from scratch.

Wi-Fi

  • SiWx917 NCP device combination does not work with Amazon/Apple/Samsung Eco systems, only works with Google in this release.
  • The external bootloader should not be used with the EFR32MG24+RS9116/SiWx917NCP device combination. Only use the internal bootloader.
  • If the user modifies the discriminator in CHIProjectconfig.h, the modified discriminator is not updated in QR code.
  • This release is not validated on the following SiWx917 SoC boards.
    • BRD4325B
    • BRD4325C
    • BRD4325G
  • LED0 (status led) is not working for window application on SiWx917 SoC device combination.
  • BRD4325A is an allowed board in Simplicity Studio, however, it is not supported in Matter.
  • SiWx917 SoC application build is failing by enabling sed component.
    • If the user want to enable sleepy feature for SiWx917 SoC, follow these steps:
      • Open matter/slc/component/matter-platform/low-power/matter_sed_wifi_917.slcc
      • Add "unless: [matter_917soc]" for power_manager component in the requires section
        • Ex:
          requires:
              - name: power_manager
                unless: [matter_917soc]
      • Create a matter project for SiWx917 SoC dual flash in Simplicity Studio.
      • Add/install "Sleepy end device component for 917" to enable SED in Simplicity Studio.
  • OTA Update: sometimes bootloading with latest image does not work with WF200 with EFR32xG24 device combination. This issue is resolved by applying the workaround described in the Wi-Fi FAQ.
  • RSI Send failure sometimes occurs within 1 hour of commissioning with the RS9116 EVK with Apple/Google Home. To recover from this issue, try one of the following:
    • Reboot the device and wait for 5-10 minutes, or
    • Erase the flash, re-flash the application and repeat commissioning.
  • Commissioning fails with an "out of memory" error when an OpenThread device in the same network was added using an Apple HomePod Mini.
  • Commissioning step 18 failure occurs occasionally:
    • This has been seen to occur more frequently with one specific access point – MI Router 4C
    • When this issue occurs, try the following steps to run commissioning successfully:
      • Delete all files in your chip-tool's /tmp folder
      • Factory Reset your access point
  • TriggerEffect command in Identify cluster does not work on EFR32xG24 with RS9116/WF200.
  • Group commands do not work for some specific access points.
