Applications

This section provides detailed lists of changes by :ref:`application <applications>`.

Machine learning

• Updated the application to enable the :ref:`Zephyr Memory Storage (ZMS) <zephyr:zms_api>` file system for the :ref:`zephyr:nrf54h20dk_nrf54h20` board.

Asset Tracker v2

• Updated the application to use the :ref:`lib_downloader` library instead of the deprecated :ref:`lib_download_client` library.

Connectivity Bridge

|no_changes_yet_note|

IPC radio firmware

• Updated the application to enable the :ref:`Zephyr Memory Storage (ZMS) <zephyr:zms_api>` file system in all devices that contain MRAM, such as the nRF54H Series devices.

Matter Bridge

• Enabled SUIT DFU support for the :ref:`matter_bridge_app` application. Currently, only the Matter OTA protocol is fully supported for SUIT DFU purposes.
• Enabled Link Time Optimization (LTO) by default for the release configuration.

nRF5340 Audio

|no_changes_yet_note|

nRF Desktop

• Updated:
  • The :ref:`nrf_desktop_failsafe` to use the Zephyr :ref:`zephyr:hwinfo_api` driver for getting and clearing the reset reason information (see the :c:func:`hwinfo_get_reset_cause` and :c:func:`hwinfo_clear_reset_cause` functions). The Zephyr :ref:`zephyr:hwinfo_api` driver replaces the dependency on the nrfx reset reason helper (see the :c:func:`nrfx_reset_reason_get` and :c:func:`nrfx_reset_reason_clear` functions).
  • The release configuration for the :ref:`zephyr:nrf54h20dk_nrf54h20` board target to enable the :ref:`nrf_desktop_failsafe` (see the :ref:`CONFIG_DESKTOP_FAILSAFE_ENABLE <config_desktop_app_options>` Kconfig option).
  • Enabled Link Time Optimization (:kconfig:option:`CONFIG_LTO` and :kconfig:option:`CONFIG_ISR_TABLES_LOCAL_DECLARATION`) by default for an nRF Desktop application image. LTO was also explicitly enabled in configurations of other images built by sysbuild (bootloader, network core image).
  • Application configurations for nRF54L05, nRF54L10, and nRF54L15 SoCs to use Fast Pair PSA cryptography (:kconfig:option:`CONFIG_BT_FAST_PAIR_CRYPTO_PSA`). Using PSA cryptography improves security and reduces memory footprint. Also increased the size of the Bluetooth receiving thread stack (:kconfig:option:`CONFIG_BT_RX_STACK_SIZE`) to prevent stack overflows.
  • Application configurations for nRF52810 and nRF52820 SoCs to reduce memory footprint:
    • Disabled Bluetooth long workqueue (:kconfig:option:`CONFIG_BT_LONG_WQ`).
    • Limited the number of key slots in the PSA Crypto core to 10 (:kconfig:option:`CONFIG_MBEDTLS_PSA_KEY_SLOT_COUNT`).
  • Disabled the :kconfig:option:`CONFIG_CLOCK_CONTROL_NRF2_GLOBAL_HSFLL_REQ_LOW_FREQ` Kconfig option in the IPC radio image configuration for the nRF54H20 SoC. This is done to ensure that the radio core requests high Global Domain (GD) frequency. The option was enabled by default, because the clock control is enabled by the Multiprotocol Service Layer (MPSL). Bluetooth stack with the SoftDevice Link Layer requires high frequency in GD to make the L2 cache and MRAM run fast to avoid code execution delays. The :ref:`nrf_desktop_dvfs` running on the application core selects the clock control and enables an automatic low GD frequency request (:kconfig:option:`CONFIG_CLOCK_CONTROL_NRF2_GLOBAL_HSFLL_REQ_LOW_FREQ`), so the application core would not request high frequency in the GD.
• Added:
  • System Power Management for the :ref:`zephyr:nrf54h20dk_nrf54h20` board target on the application and radio cores. The application still has high power consumption as the Bluetooth LE controller running on the radio core requires disabling MRAM latency (:kconfig:option:`CONFIG_MRAM_LATENCY_AUTO_REQ`). Enabling MRAM latency makes the Bluetooth LE controller unstable.
  • Application configurations for the nRF54L05 and nRF54L10 SoCs (emulated on the nRF54L15 DK). The configurations are supported through nrf54l15dk/nrf54l10/cpuapp and nrf54l15dk/nrf54l05/cpuapp board targets. For details, see the :ref:`nrf_desktop_board_configuration`.
  • The dongle_small configuration for the nRF52833 DK. The configuration enables logs and mimics the dongle configuration used for small SoCs.

nRF Machine Learning (Edge Impulse)

|no_changes_yet_note|

Serial LTE modem

• Added an overlay :file:`overlay-memfault.conf` file to enable Memfault. For more information about Memfault features in |NCS|, see :ref:`mod_memfault`.
• Updated the application to use the :ref:`lib_downloader` library instead of the deprecated :ref:`lib_download_client` library.

Thingy:53: Matter weather station

• Enabled Link Time Optimization (LTO) by default for the release configuration.

Samples

This section provides detailed lists of changes by :ref:`sample <samples>`.

Amazon Sidewalk samples

|no_changes_yet_note|

Bluetooth samples

• Added support for the nrf54l15dk/nrf54l05/cpuapp and nrf54l15dk/nrf54l10/cpuapp board targets in the following samples:
  • :ref:`bluetooth_central_hids`
  • :ref:`peripheral_hids_keyboard`
• :ref:`direct_test_mode` sample:
  • Added loading of radio trims and a fix of a hardware errata for the nRF54H20 SoC to improve the RF performance.
• :ref:`central_uart` sample:

Bluetooth Fast Pair samples

• Added support for the nrf54l15dk/nrf54l05/cpuapp and nrf54l15dk/nrf54l10/cpuapp board targets in all Fast Pair samples.

• Updated the non-secure target (nrf5340dk/nrf5340/cpuapp/ns and thingy53/nrf5340/cpuapp/ns) configurations of the following samples to use configurable TF-M profile instead of the predefined minimal TF-M profile:

  • :ref:`fast_pair_locator_tag`

    • :ref:`bt_mesh_chat`
    • :ref:`bluetooth_mesh_light_switch`
    • :ref:`bluetooth_mesh_silvair_enocean`
    • :ref:`bluetooth_mesh_light_dim`
    • :ref:`bluetooth_mesh_light`
    • :ref:`bluetooth_mesh_light_lc`

• Updated the following samples to include the value of the :kconfig:option:`CONFIG_BT_COMPANY_ID` option in the Firmware ID:

  • :ref:`ble_mesh_dfu_distributor`
  • :ref:`ble_mesh_dfu_target`

Cellular samples

• Updated the following samples to use the :ref:`lib_downloader` library instead of the :ref:`lib_download_client` library:

  • :ref:`http_application_update_sample`
  • :ref:`http_modem_delta_update_sample`
  • :ref:`http_modem_full_update_sample`
  • :ref:`location_sample`

    • An issue with an uninitialized variable in the :c:func:`handle_at_cmd_requests` function.
    • An issue with the too small :kconfig:option:`CONFIG_COAP_EXTENDED_OPTIONS_LEN_VALUE` Kconfig value in the :file:`overlay-coap_nrf_provisioning.conf` file.
    • Slow Wi-Fi connectivity startup by selecting TFM_SFN instead of TFM_IPC.
    • The size of TLS credentials buffer for Wi-Fi connectivity to allow installing both AWS and CoAP CA certificates.
