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.

Binary libraries

No changes since the latest nRF Connect SDK release.

Bluetooth libraries and services

• Bluetooth LE advertising providers:

  • Added the CONFIG_BT_ADV_PROV_TX_POWER_CORRECTION_VAL option to TX power advertising data provider (CONFIG_BT_ADV_PROV_TX_POWER). The option adds a predefined value to the TX power, that is included in the advertising data.

  • Changed bt_le_adv_prov_adv_state.bond_cnt to bt_le_adv_prov_adv_state.pairing_mode. The information about whether the advertising device is looking for a new peer is more meaningful for the Bluetooth LE data providers.

• Bluetooth mesh profile library:

  • Bluetooth mesh provisioning handler for Nordic DKs module: Changed the UUID generation to prevent trailing zeros in the UUID.

    Migration note: To retain the legacy generation of UUID, enable the option CONFIG_BT_MESH_DK_LEGACY_UUID_GEN.

See Bluetooth mesh samples for the list of changes for the Bluetooth mesh samples.

• Scanning module:

  • Added the ability to use the module when the Bluetooth Observer role is enabled.

• Google Fast Pair Service (GFPS) service:

  • Disabled automatic security re-establishment request as a peripheral (CONFIG_BT_GATT_AUTO_SEC_REQ) to allow the Fast Pair Seeker to control the security re-establishment.

Bootloader libraries

No changes since the latest nRF Connect SDK release.

Modem libraries

• Modem information library:

  • Removed:

    • modem_info_json_string_encode() and modem_info_json_object_encode() functions.

    • network_mode field from network_param.

    • MODEM_INFO_NETWORK_MODE_MAX_SIZE.

    • CONFIG_MODEM_INFO_ADD_BOARD.

• Modem library integration layer library:

  • Updated:

    • The getaddrinfo() function to return EAFNOSUPPORT instead of EPROTONOSUPPORT when socket family is not supported.

    • The bind() function to return EAFNOSUPPORT instead of ENOTSUP when socket family is not supported.

    • The sendto() function to return EAFNOSUPPORT instead of ENOTSUP when socket family is not supported.

    • The connect() function to not override the error codes set by the Modem library when called with raw parameters (non-IP).

  • Fixed:

    • An issue where the getsockopt() function causes segmentation fault when the optlen parameter is provided as NULL.

    • An issue where the recvfrom() function causes segmentation fault when the from and fromlen parameters are provided as NULL.

Libraries for networking

• Multicell location library:

  • Removed the Kconfig option CONFIG_MULTICELL_LOCATION_MAX_NEIGHBORS. The maximum number of supported neighbor cell measurements for HERE location services depends on the CONFIG_LTE_NEIGHBOR_CELLS_MAX Kconfig option.

• Download client library:

  • Updated the library so that it does not retry download on disconnect.

  • Fixed a race condition when starting the download.

• nRF Cloud library:

  • Updated:

    • The stack size of the MQTT connection monitoring thread can now be adjusted by setting the CONFIG_NRF_CLOUD_CONNECTION_POLL_THREAD_STACK_SIZE Kconfig option.
