Samples

This section provides detailed lists of changes by sample, including protocol-related samples. For lists of protocol-specific changes, see Protocols.

Bluetooth samples

• Added:

  • Bluetooth: Multiple advertising sets sample.

  • Bluetooth: nRF Distance Measurement with Bluetooth LE discovery sample.

• Updated:

  • Bluetooth: Peripheral Running Speed and Cadence Service (RSCS) - Corrected the number of bytes for setting the Total Distance Value and specified the data units.

  • Bluetooth: Direct Test Mode - Added support for front-end module devices that support 2-pin PA/LNA interface with additional support for the Skyworks SKY66114-11 and the Skyworks SKY66403-11.

  • Bluetooth: Peripheral HIDS mouse - Added a notice about encryption requirement.

  • Bluetooth: Peripheral HIDS keyboard - Added a notice about encryption requirement.

  • Bluetooth: Central and Peripheral HRS - Clarified the “Requirements” section and fixed a link in the “Testing” section of the document.

nRF9160 samples

• nRF9160: Modem Shell sample:

  • Added a new shell command cloud for establishing an MQTT connection to nRF Cloud.

  • Added support for minimal assistance using factory almanac, time and location.

  • Added support for TTFF test mode.

• nRF9160: HTTP update samples:

  • HTTP update samples now set the modem in the power off mode after the firmware image download completes. This avoids ungraceful disconnects from the network upon pressing the reset button on the kit.

Thread samples

• Thread: CLI sample:

  • Removed overlay-thread_1_2.conf as Thread 1.2 is now supported as described in Thread Specification options.

Other samples

Radio test - Added support for front-end module devices that support 2-pin PA/LNA interface with additional support for the Skyworks SKY66114-11 and the Skyworks SKY66403-11.

• Secure Partition Manager sample:

  • Bug fixes:

    • NCSDK-12230: Fixed an issue where low baud rates would trigger a fault by selecting as system clock driver SYSTICK instead of RTC1.

Drivers

This section provides detailed lists of changes by driver.

• No changes since the latest nRF Connect SDK release.

Libraries

This section provides detailed lists of changes by library.

Bluetooth libraries and services

• Running Speed and Cadence Service (RSCS) library:

  • Added units for bt_rscs_measurement members.

• Bluetooth Low Energy Remote Procedure Call library:

  • Fixed the issue related to missing buffer size variables for the user PHY update and the user data length update procedures.

Common Application Framework (CAF)

• Added a simple implementation of the CAF: Bluetooth LE bond module. The implementation allows to erase bonds for default Bluetooth local identity.

• Migrated nRF Desktop settings loader to Common Application Framework as CAF: Settings loader module.

• CAF: LEDs module:

  • Added new LED effect macro: LED_EFFECT_LED_BLINK2.

  • Added a macro to pass color arguments between macro calls: LED_COLOR_ARG_PASS.

• Updated:

  • Unify module ID reference location. The array holding module reference objects is explicitly defined in linker script to avoid creating an orphan section. MODULE_ID macro and module_id_get() function now returns module reference from dedicated section instead of module name. The module name can not be obtained from reference object directly, a helper function (module_name_get()) should be used instead.

  • Fixed the NCSDK-13058 known issue related to directed advertising in CAF.

  • Fixed NULL dereferencing in CAF: Sensor manager module during wake_up_event handling for sensors that do not support trigger.

Bootloader libraries

• Added a separate section for Bootloader libraries.

Libraries for networking

• FOTA download library: * Skipping host name check when connecting to TLS service using just IP address.

Modem libraries

• Modem library integration layer library:

  • Fixed a bug in the socket offloading component, where the recvfrom() wrapper could do an out-of-bounds copy of the sender’s address, when the application is compiled without IPv6 support. In some cases, the out of bounds copy could indefinitely block the send() and other socket API calls.

• AT monitor library:

  • Introduced AT_MONITOR_ISR macro to monitor AT notifications in an interrupt service routine.

  • Removed at_monitor_init() function and CONFIG_AT_MONITOR_SYS_INIT option. The library now initializes automatically when enabled.

• AT command parser library:

  • Can now parse AT command responses containing the response result, for example, OK or ERROR.

• Modem library integration layer:

  • The modem trace handling is moved from nrf_modem_os.c to a new file nrf_modem_lib_trace.c, which also provides the API for starting a trace session for a given time interval or until a given size of trace data is received.

Event manager

• Added:

  • EVENT_SUBSCRIBE_FIRST subscriber priority.

• Updated:

  • Modified the sections used by the event manager. Stopped using orphaned sections. Removed forced alignment for x86. Reworked priorities.

  • Event manager no longer uses orphaned sections to store information about event types, listeners and subscribers. Hence, the CONFIG_LINKER_ORPHAN_SECTION_PLACE option is no longer required in the config file.

Event manager Profiler Tracer

• Updated:

  • Event manager Profiler Tracer no longer use orphaned sections to store profiler information. Hence, the CONFIG_LINKER_ORPHAN_SECTION_PLACE option is no longer required in the config file.

Libraries for networking

• FOTA download library:

  • Fixed an issue where the application would not be notified of errors originating from inside download_with_offset(). In the http_update samples, this would result in the dfu start button interrupt being disabled after a connect error in download_with_offset() after a disconnect during firmware download.

• DFU target library:

  • Updated the implementation of modem delta upgrades in the DFU target library to use the new socketless interface provided by the Modem library.

• Location library:

  • Added A-GPS filtered ephemerides support.

• nRF Cloud library:

  • Added A-GPS filtered ephemerides support, with ability to set matching threshold mask angle.

  • When filtered ephemerides is enabled, A-GPS assistance requests to cloud are limited to no more than once every two hours.

  • Updated MQTT connection error handling. Now, unacknowledged pings and other errors result in a transition to the disconnected state. This ensures that reconnection can take place.

• nRF Cloud REST library:

  • Updated to use the REST client library for REST API calls.

Other libraries

• Moved Bootloader libraries to a section of their own. * Added write protection by default for the image partition.

• Date-Time library:

  • Removed the CONFIG_DATE_TIME_IPV6 Kconfig option. The library now automatically uses IPv6 for NTP when available.

• Location library:

  • Added support for GNSS high accuracy.

Event Manager

• Modified sections used by the Event Manager and stopped using orphaned sections.

• Removed forced alignment for x86.

• Reworked priorities.

sdk-nrfxlib

See the changelog for each library in the nfxlib documentation for additional information.

Scripts

This section provides detailed lists of changes by script.

Unity

• Fixed bug that resulted in the mocks for some functions not having the __wrap_ prefix. This happened for functions declared with whitespaces between identifier and parameter list.

HID Configurator

• Added:

  • HID Configurator now recognizes the bootloader variant as a DFU module variant for the configuration channel communication. The new implementation is backward compatible: the new version of the script checks for module name and acts accordingly.
