Known Issues

General

  • The Matter logs are now printed to the UART interface by default. To view the logs use the Simplicity Studio console or a standalone terminal emulator such as PuTTY. The logging destination can be controlled by installing the "Logging To UART" or the "Logging to RTT" component under Matter -> Platform -> Utils in a Matter Studio project.  
  • 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.
  • Upgrades of projects based on the Lighting application require the that user manually removes the references to OnOffSwitchConfiguration  from ZclCallbacks.cpp.
  • 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).
  • The configuration parameters for the internal storage bootloader used in the OTA software updates must always be custom-configured based on the actual image size for the given application. See https://docs.silabs.com/matter/2.4.0/matter-ota/01-ota-bootloader.

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.
  • 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)
  • In some cases the Zigbee Matter Light (sequential variant) may fail to transmit the NotifyUpdateApply command after an OTA Software update.
  • Zigbee Matter Light commissioning failure due to kFindOperationalForStayActive timeout can occur. (UID: 1360555)
  • On rare occurance, Zigbee Matter Light cli becomes unresponsive. Device reboot is required (UID: 1337094).
  • After a power cycle, Zigbee Matter Light mays become un-reachable from the controller due to a SRP request timeout. Device recovers after a reboot (UID: 1360564)
  • CurrentHeapHighWatermark sometimes gets reported improperly to the Matter layer from the platform code (UID: 1336190)
  • SILABS_LOG() having intermittent issues in ZigbeeMatterLight app (UID: 1348606)
  • ZigbeeMatterLight app may fail to build when created using the 'Copy contents' option (UID: 1348601)
  • Matter ICD over Thread may rarely not enter sleep/idle its radio until the next poll phase due to waiting on a TX ACK operation (UID: 1362030; 1362028)

Wi-Fi

  • In high traffic Environment, mDNS timeout is seen with SiWx917 SoC and NCP.
  • In high-traffic environment, sometimes command timeouts are seen as the processing of the command takes more than 20 seconds.
  • Below issues are observed on SiWx917 SoC:

    • The BRD4342A PSRAM support is enabled only for the text segment; it is not working for the data segment.

    • The M4 OTA upgrade is failing on the BRD4342A board.

    • Commissioning in the Apple ecosystem fails with provisioned SiWx917 SoC boards. When using the Provision tool on the 917, the default Custom flow and Discovery Bitmask are incorrect. The workaround is to specify the correct values for provisioning by adding the following arguments: -sf 0 -sr 6

    • Matter applications fails to re-join the DUT after a power cycle of the access point in all ecosystems.

    • In the window app, the device goes offline after successful commissioning in Apple ecosystem.

    • The multi-sensor app experiences a hang issue with the Apple ecosystem.

    • PASE Session timeout was observed occasionally while commissioning a second fabric.

    • In the fan control app, during step increase/decrease, the speed updates properly, but percent-current and percent-setting are not updating as expected.

    • 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).

    • The P37 pin should be pulled up to enable the Matter shell for sleepy applications.

    • 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=<WSTK_IP>
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 RS9116 EVK:
    • RSI send failure and SPI timeout issues are observed with the 9116, causing a timeout issue during command processing.
    • 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.
  • 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.
  • Commissioning fails with an "out of memory" error when an OpenThread device in the same network was added using an Apple HomePod Mini.
  • 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.
  • Provisioning on the SiWx917 boards requires version 1.16.12 of the Simplicity Commander.
