Features 

This is the Silicon Labs Matter v2.3.1-1.3 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, SLC-CLI or Visual Studio Code.

This release is certifiable to the Connectivity Standards Alliance (CSA) Matter 1.3 certification program (https://csa-iot.org/) for Thread (MG24 / MG26), Wi-Fi 917 SoC and NCP platform (MG24/WF200).

This release supports only series 2 devices. Series 3 will come in a future release. Use v2.2.x-1.2 for series 1 devices.

  • To get started, download Simplicity Studio from the following link: https://www.silabs.com/developers/simplicity-studio, and install Simplicity SDK v2024.6.1 along with Silicon Labs Matter v2.3.1. For SiWx917, install WiSeConnect v3.3.1 as well.
    • If using WiseConnect v2.3.2 instead of WiseConnect v2.3.1, soc_configuration_enable component will need to be manually added to SiWx917 SoC projects for the compilation to pass. This component can be installed through the Simplicity Studio UI: WiseConnect3 SDK v3.3.2 -> Device -> Si91x -> MCU -> Core -> ENABLE USER CONFIGURATION.

Known Issues

General

  • On some EFR32 boards the RTT logs might not display correctly. The workaround is to use the "-device EFR32MG12PXXXF1024" and "-if SWD" parameters when invoking JLinkExe.
  • The Matter device images require approximately 700k in flash space. As a result only a subset of EFR32MG2x devices are supported. For a complete list of devices supported consult the documentation located at Matter Hardware Requirements.
  • 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-Wi-Fi 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.
  • An upgrade of an existing Studio project from Matter 2.2.2-1.2 or earlier to the current version of the extension is not supported.
  • In some rare cases a Simplicity Studio project build may fail due to missing files in the zap-generated/  directory (e.g. "gen_config.h not found").
    • Workaround: Delete the .zap folder in the home directory.
  • The Simplicity Studio project upgrade dialog can be exited only by closing the project tab (clicking on the "x" button in the top right corner).
  • Incorrect state error sometimes while commissioning another fabric.
  • Window App device goes offline after commissioning with the Apple Ecosystem.
  • Unbolt feature is not supported via the ecosystems like Apple, Samsung and Amazon Alexa but it is supported by our device default due to which Unlock with these Ecosystem will fail. To disable unbolt feature, the feature bit for the DoorLock Cluster should be update from 0x1DB3 to 0xDB3.
  • Due to an electrical issue on the WPK main boards (BRD4002x), sometimes the current measurement value reported is wrong in the Energy Profiler, making it seem like an ICD is not going to sleep properly even though it is. This issue does not happen when using a WSTK (BRD4001x). (UID: 1197733 & 1228823).

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, ~2 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.
  • The Matter Zigbee sequential CMP app does not properly disconnect/shutdown the Zigbee network once it joined the Matter/Thread network.
  • Matter attestation credentials can conflict with Lockbits in Series 2, requiring moving the location of the attestation credentials when lockbits are used. Please see the guide Moving the Matter Attestation Credentials on Series 2 (MG24) for details. (UID: 1235425)
  • Installing the OpenThread Certification Libraries component in a Matter Studio project results in "error: unused parameter" compilation errors.
    • Workaround: In Studio -> Project Properties -> C/C++ Build -> Settings -> Tool Settings -> [GNU Arm C Compiler and GNU Arm C++ Compiler] -> Miscellaneous -> Other Flags – delete the "-Werror=unused-parameter" flag.

Wi-Fi

  • Below issues are observed on SiWx917 SoC:
    • OTA upgrade and factory reset doesn't not work without reset button with Jlink.
    • mDNS timeout issues are occasionally observed while processing the commands.
    • In high-traffic environment, sometimes command timeouts are seen as the processing of the command takes more than 20 seconds for sleepy apps.
    • Observed CASE session timeout rarely during sigma packet transaction while sending a unicast command with the Lock Sleepy app, which sometimes results in a resource busy error from the device (until the device commissioning times out).
    • Sometimes Chip tool returns "No matching device found" failure for BLE advertisement.
    • When Sleepy is enabled, Jlink gets disconnected resulting in RTT logging issue. In order to capture logs during sleepy, enable UART on serial terminal.
    • The P37 pin should be pulled up to enable the Matter shell for sleepy applications.
    • Sometimes observed random commissioning failures.
    • Stability issue with the Thermostat application during command processing.
    • Sometimes the SiWx917 might not work properly with commander, but with the latest commander (v1.16.11), this issue is not observed. Steps to recover the board are provided below:
    export WSTK_IP=10.104.66.13
commander device info --ip $WSTK_IP --device SiWG917M111MGTBA
commander adapter reset --ip $WSTK_IP
commander device masserase --ip $WSTK_IP --device SiWG917M111MGTBA
commander adapter reset --ip $WSTK_IP
commander manufacturing erase userdata --ip $WSTK_IP --device SiWG917M111MGTBA
commander adapter reset --ip $WSTK_IP
commander flash <path-to-rps> --ip $WSTK_IP --device "SiWG917M111MGTBA"
commander rtt connect --noreset --ip $WSTK_IP --device SiWG917M111MGTBA | tee dut.log
  • Below issues are observed on SiWx917 NCP:
    • mDNS timeout issues are occasionally observed while processing the commands.
    • In high-traffic environment, sometimes command timeouts are seen as the processing of the command takes more than 20 seconds for sleepy apps.
    • Sometimes random commissioning failures are observed.
  • Below issues are observed on RS9116 EVK:
    • Intermittent Init failures are observed after resetting the device.
    • When LCD is enabled, in order to reset the device properly, reset button to be pressed until the Silabs logo appeared on the LCD.
  • In EFR32MG24+WF200 device combination, WF200 Firmware exception is observed when both ICD and matter shell is enabled. In order to make matter shell to work for Lock application with this device combination, ICD is disabled. 
  • 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.
  • OTA Update: sometimes boot loading with latest image does not work with WF200 with EFR32xG24 device combination. This issue is resolved by applying the workaround described in the Matter 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.
  • TriggerEffect command in Identify cluster and Group commands only work for some specific access points when IGMP snooping is disabled.
  • When setting up the Ozone Debugger on Mac the location of the JLinkDevices.xml file has moved, Follow this documentation in order to place it in the proper location.
  • RS9116 and WF200 apps do not build with VS Code as generator.
