The Location module triggers a
location_request()
with GNSS being the first priority method and cellular the second priority if they are enabled in the application configuration.A-GPS/P-GPS are not requested based on triggers in the application but only based on Location library events
LOCATION_EVT_GNSS_ASSISTANCE_REQUEST
andLOCATION_EVT_GNSS_PREDICTION_REQUEST
.Currently, you cannot configure or define the LTE LC neighbor cell search type with the Location library. The default search type is always used.
The Kconfig option
CONFIG_GNSS_MODULE_PGPS_STORE_LOCATION
(callingnrf_cloud_pgps_set_location()
) is not supported in the Location library.
Removed:
GNSS module.
A-GPS and P-GPS processing. It is now handled by the nRF Cloud library.

CONFIG_NRF_PROFILER_SHELL
Kconfig option. The option can be used to disable the nRF Profiler shell commands.
Common Application Framework (CAF)
CAF: Bluetooth LE state module:
Added
CONFIG_CAF_BLE_STATE_MAX_LOCAL_ID_BONDS
. The option allows to specify the maximum number of allowed bonds in each Bluetooth local identity for a Bluetooth Peripheral.
-
Added:
Dynamic control for the sensor sample period.
Test for the sample.
DFU libraries
DFU target library:
Added new types
DFU_TARGET_IMAGE_TYPE_ANY_MODEM
andDFU_TARGET_IMAGE_TYPE_ANY_APPLICATION
. This makes any supported modem update type acceptable when downloading.Updated the library such that calling the
dfu_target_reset()
function clears all images that have already been downloaded into a target area. This allows cancelling any update packages even if they are already marked to be updated.
MPSL libraries
sdk-nrfxlib
See the changelog for each library in the nrfxlib documentation for additional information.
Scripts
-
Updated the SPDX License List database to version 3.18.
-
Added:
CONFIG_PM_PARTITION_ALIGN_SETTINGS_STORAGE
Kconfig option to specify the alignment of the settings storage partition.CONFIG_PM_EXTERNAL_FLASH_HAS_DRIVER
Kconfig option. This option must be selected by drivers providing support for external flash. It is automatically selected byCONFIG_NORDIC_QSPI_NOR
andCONFIG_SPI_NOR
. MCUboot might fail to boot when the external flash memory is used for non-primary application images and when the driver for the external flash memory is not enabled. See Using external flash memory partitions and External flash memory partitions for details.P-GPS partition section to the
ncs/nrf/subsys/partition_manager/Kconfig
file.Board-specific static Partition Manager configuration shared among build types. The configuration can be defined in the board’s directory.
Updated the
ncs/nrf/subsys/partition_manager/pm.yml.pgps
file to place P-GPS partition in external flash when so configured.Fixed an issue with the driver and devicetree symbol for the external flash memory where the driver was sometimes NULL, even if the DT node was chosen.
Note
If your project includes MCUboot and uses external flash for storing secondary images, after applying this fix, you need to configure
nordic,pm-ext-flash
property in a devicetree overlay for the MCUboot child image. Otherwise, MCUboot will not be able to read a flash area in the external flash to pick up a new firmware image.
Unity:
Added:
Support for excluding functions from mock generation. This provides a framework to implement custom mocks.
Updated:
The generated mock functions have been renamed from
__wrap
to__cmock
.The generated mock headers have been renamed from
mock_<header_file>.h
tocmock_<header_file>.h
.The compiler option
--defsym
is used instead of--wrap
.
MCUboot
The MCUboot fork in nRF Connect SDK (sdk-mcuboot
) contains all commits from the upstream MCUboot repository up to and including cfec947e0f8be686d02c73104a3b1ad0b5dcf1e6
, with some nRF Connect SDK specific additions.
The code for integrating MCUboot into nRF Connect SDK is located in the ncs/nrf/modules/mcuboot
folder.
The following list summarizes both the main changes inherited from upstream MCUboot and the main changes applied to the nRF Connect SDK specific additions:
Added:
Precise check of the image size.
CONFIG_USE_NRF53_MULTI_IMAGE_WITHOUT_UPGRADE_ONLY
Kconfig option to specify that you want to use nRF53 multi-image upgrade without the upgrade only setting in MCUboot. Enabling this option has drawbacks. See the Developing with nRF53 Series user guide for details.CONFIG_BOOT_SERIAL_MAX_RECEIVE_SIZE
Kconfig option to specify the size of the serial recovery command buffer, which was previously fixed at 512 bytes. The new default value is 1024 bytes to allow for larger commands (and increased transfer speed).
Updated loader by adding post copy hook to swap function.
Fixed:
RAM loading for Arm with correct handling of vector table when code has moved to RAM.
An issue with QSPI stack alignment in serial recovery, which prevented writing data to QSPI slots.
An issue in serial recovery where rc is wrongly returned as an unsigned integer.
Zephyr
The Zephyr fork in nRF Connect SDK (sdk-zephyr
) contains all commits from the upstream Zephyr repository up to and including cd16a8388f71a6cce0cea871f75f6d4ac8f56da9
, with some nRF Connect SDK specific additions.
For the list of upstream Zephyr commits (not including cherry-picked commits) incorporated into nRF Connect SDK since the most recent release, run the following command from the ncs/zephyr
repository (after running west update
):
git log --oneline cd16a8388f ^71ef669ea4
For the list of nRF Connect SDK specific commits, including commits cherry-picked from upstream, run:
git log --oneline manifest-rev ^cd16a8388f
The current nRF Connect SDK main branch is based on revision cd16a8388f
of Zephyr.
Trusted Firmware-M
Added:
Reading, updating, and attesting the lifecycle state stored in nRF OTP. The storage is managed by the Bootloader storage library.
