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 pre-2.4.0-1.4 projects based on the Lighting application require 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/2.5.1/matter-ota/01-ota-bootloader.
  • For ICD applications, after upgrading the project, users should update the configuration values in the ICD Server Configuration  component accordingly.
  • ConnectMaxTimeSeconds attribute (and others) exposed by ZAP even though it cannot be modified (read only). Work in progress in PR#36516. (UID: 1370882)
  • Updated instructions on using JLink RTT logging with our JLinkDevices.xml file. (UID: 1387981)
  • Issue when adding custom clusters to the Matter sample apps when following the standard instructions. Please see the workaround available here. (UID: 1403766)

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)
  • The StartUpOnOff attribute of the OnOff cluster in the Zigbee Matter Light application does not maintain its setting after a reboot (UID: 1381037)
  • When creating a project for BRD4350A and BRD4351A boards it is recommended to rely on Studio auto-detecting the board revision. Otherwise make sure to select the correct board revision. 
  • Zigbee Matter Light, in rare occurrence, will momentarily fail to receive packages over 15.4 when utilizing BLE DMP with Thread. This may result in OTA update image transfer failures. (UID: 1367027)
  • When a ZigbeeMatterLight project on a BRD1019A board is upgraded from Matter 2.5.0 to this release the SL_RAIL_UTIL_PTI_MODE configuration parameter is set to RAIL_PTI_MODE_DISABLED. 
  • Erroneous RAM usage (100%) reported for Matter sample apps compiled in Studio for EFR32 parts. (UID: 1406918)
  • Issue where after a power cycle, Zigbee Matter Light may become unreachable from the controller due to a SRP request timeout. Device recovers after a reboot. (UID: 1360564)

Wi-Fi

  • In high traffic environment, mDNS timeout is seen with SiWx917 SoC and NCP.
  • In high-traffic environment, sometimes command timeouts are seen due to packet delays/drops.
  • Enabling "Logging to RTT" with SiWx917 SoC results in OTA update failure due to JLink connection preventing soft reset.
  • 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.
    • BLE scan issues are observed with Raspberry Pi when the distance between the device and the controller exceeds 1.5 meters.
    • Applications from this release are not backward compatible with 2.5-1.4, but are compatible with the 2.4-1.4 release and prior.
    • Commissioning failure for the Windows Sleepy app with the Samsung ecosystem.
    • Multi-admin test case fails for sleepy applications with Samsung ecosystems.
    • Observed CASE session timeout 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.
    • The color control moves at a different rate than specified in the chip-tool command.
  • 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.
  • 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.
  • SiWx917 NCP M4 OTA upgrade with upgraded Wiseconnect SDK may not be backward compatible with the existing TA.
  • 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.
  • With EFR32 MG24 + RS9116 after going idle for some time, Apple devices may not be able to control an LED. (UID: 1085568)
  • 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.
  • LCD is disabled on RS9116 and SiWx917 NCP.
