Protocols

This section provides detailed lists of changes by protocol. See Samples for lists of changes for the protocol-related samples.

Bluetooth® LE

No changes since the latest nRF Connect SDK release.

Bluetooth Mesh

• Updated:

  • The Kconfig option CONFIG_BT_MESH_DFU_METADATA_ON_BUILD to no longer depend on the Kconfig option CONFIG_BT_MESH_DFU_METADATA.

  • The Kconfig option CONFIG_BT_MESH_DFU_CLI to no longer enable the Kconfig option CONFIG_BT_MESH_DFU_METADATA_ON_BUILD by default. The Kconfig option CONFIG_BT_MESH_DFU_METADATA_ON_BUILD can still be manually enabled.

  • The JSON file, added to dfu_application.zip during the automatic DFU metadata generation, to now contain a field for the core_type used when encoding the metadata.

Matter

• Added:

  • Support for merging the generated factory data HEX file with the firmware HEX file by using the devicetree configuration, when Partition Manager is not enabled in the project.

  • Support for the unified Persistent Storage API, including the implementation of the PSA Persistent Storage.

  • Watchdog timer implementation for creating multiple Matter watchdog sources and monitoring the time of executing specific parts of the code.

• Updated default MRP retry intervals for Thread devices to two seconds to reduce the number of spurious retransmissions in Thread networks.

• Increased the number of available packet buffers in the Matter stack to avoid packet allocation issues.

Matter fork

The Matter fork in the nRF Connect SDK (sdk-connectedhomeip) contains all commits from the upstream Matter repository up to, and including, the v1.3.0.0 tag.

The following list summarizes the most important changes inherited from the upstream Matter:

• Added:

  • Support for the Scenes cluster. This enables users to control the state for devices, rooms, or their whole home, by performing multiple actions on the devices that can be triggered with a single command.

  • Support for command batching. This allows a controller to batch multiple commands into a single message, which minimizes the delay between execution of the subsequent commands.

  • Extended beaconing feature that allows an accessory device to advertise Matter service over Bluetooth LE for a period longer than maximum time of 15 minutes. This can be enabled using the CONFIG_CHIP_BLE_EXT_ADVERTISING Kconfig option.

  • The Kconfig options CONFIG_CHIP_ICD_LIT_SUPPORT, CONFIG_CHIP_ICD_CHECK_IN_SUPPORT, and CONFIG_CHIP_ICD_UAT_SUPPORT to manage ICD configuration.

  • New device types:

    • Device energy management

    • Microwave oven

    • Oven

    • Cooktop

    • Cook surface

    • Extractor hood

    • Laundry dryer

    • Electric vehicle supply equipment

    • Water valve

    • Water freeze detector

    • Water leak detector

    • Rain sensor

• Updated:

  • Network commissioning to provide more information related to the used networking technologies. For Wi-Fi devices, they can now report which Wi-Fi band they support and they have to perform Wi-Fi directed scanning. For Thread devices, the Network Commissioning cluster now includes Thread version and supported Thread features attributes.

No changes since the latest nRF Connect SDK release.

Thread

• Initial experimental support for nRF54L15 for the Thread CLI and Co-processor samples.

• Added new feature set option CONFIG_OPENTHREAD_NORDIC_LIBRARY_RCP.

Zigbee

• Fixed an issue with Zigbee FOTA updates failing after a previous attempt was interrupted.

Gazell

No changes since the latest nRF Connect SDK release.

Enhanced ShockBurst (ESB)

• Added support for the nRF54H20 DK and nRF54L15 PDK boards.

• Added fast switching between radio states for the nRF54H20 SoC.

• Added fast radio channel switching for the nRF54H20 SoC.

nRF IEEE 802.15.4 radio driver

No changes since the latest nRF Connect SDK release.

Wi-Fi

No changes since the latest nRF Connect SDK release.

Applications

This section provides detailed lists of changes by application.

Asset Tracker v2

• Updated:

  • The MQTT topic name for A-GNSS requests is changed to agnss for AWS and Azure backends.

  • GNSS heading is only sent to the cloud when it is considered accurate enough.

Serial LTE modem

• Removed:

  • Mention of Termite and Teraterm terminal emulators from the documentation. The recommended approach is to use one of the emulators listed on the Testing and optimization page.

  • Sending GNSS UI service info to nRF Cloud; this is no longer required by the cloud.

• Updated:

  • AT command parsing to utilize the Custom AT commands library.

nRF5340 Audio

• Added CAP initiator for the Bluetooth LE Audio unicast (CIS) client.

• Removed:

  • The LE Audio controller for nRF5340 library. The only supported controller for LE Audio is SoftDevice Controller. This enables use of standard tools for building, configuring, and DFU.

• Updated:

  • Low latency configuration to be used as default setting for the nRF5340 Audio application.

nRF Machine Learning (Edge Impulse)

• Updated the ml_runner application module to allow running a machine learning model without anomaly support.

nRF Desktop

• Added:

  • Support for the nRF54L15 PDK with the nrf54l15pdk_nrf54l15_cpuapp board target. The PDK can act as a sample mouse or keyboard. It supports the Bluetooth LE HID data transport and uses SoftDevice Link Layer with Low Latency Packet Mode (LLPM) enabled. The PDK uses MCUboot bootloader built in the direct-xip mode (MCUBOOT+XIP) and supports firmware updates using the Device Firmware Upgrade module.

  • The nrfdesktop-wheel-qdec DT alias support to Wheel module. You must use the alias to specify the QDEC instance used for scroll wheel, if your board supports multiple QDEC instances (for example nrf54l15pdk_nrf54l15_cpuapp). You do not need to define the alias if your board supports only one QDEC instance, because in that case, the wheel module can rely on the qdec DT label provided by the board.

• Updated:

  • The CONFIG_BT_ADV_PROV_TX_POWER_CORRECTION_VAL Kconfig option value in the nRF52840 Gaming Mouse configurations with the Fast Pair support. The value is now aligned with the Fast Pair requirements.

  • Enabled the CONFIG_DESKTOP_CONFIG_CHANNEL_OUT_REPORT Kconfig option for the nRF Desktop peripherals with Device Firmware Upgrade module. The option mitigates HID report rate drops during DFU image transfer through the nRF Desktop dongle. The output report is also enabled for the nrf52kbd_nrf52832 build target in the debug configuration to maintain consistency with the release configuration.

  • Replaced the CONFIG_BT_L2CAP_TX_BUF_COUNT Kconfig option with CONFIG_BT_ATT_TX_COUNT in nRF Desktop dongle configurations. This update is needed to align with the new approach introduced in sdk-zephyr by commit a05a47573a11ba8a78dadc5d3229659f24ddd32f.

  • The HID forward module no longer uses a separate HID report queue for a HID peripheral connected over Bluetooth LE. The module relies only on the HID report queue of a HID subscriber. This is done to simplify implementation, reduce memory consumption and speed up retrieving enqueued HID reports. You can modify the enqueued HID report limit through the CONFIG_DESKTOP_HID_FORWARD_MAX_ENQUEUED_REPORTS Kconfig option.

Thingy:53: Matter weather station

No changes since the latest nRF Connect SDK release.

Matter Bridge

• Added:

  The CONFIG_BRIDGE_BT_MAX_SCANNED_DEVICES Kconfig option to set the maximum number of scanned Bluetooth LE devices. The CONFIG_BRIDGE_BT_SCAN_TIMEOUT_MS Kconfig option to set the scan timeout.

• Updated the implementation of the persistent storage to leverage NonSecure-prefixed methods from the common Persistent Storage module.

• Changed data structure of information stored in the persistent storage to use less settings keys. The new structure uses approximately 40% of the memory used by the old structure, and provides a new field to store user-specific data.

  Backward compatibility is kept by using an internal dedicated method that automatically detects the older data format and performs data migration to the new representation.

IPC radio firmware

• Added support for the nRF54H20 DK board.
