nRF Connect SDK v2.1.0 Release Notes

nRF Connect SDK delivers reference software and supporting libraries for developing low-power wireless applications with Nordic Semiconductor products in the nRF52, nRF53, nRF70, and nRF91 Series. The SDK includes open source projects (TF-M, MCUboot, OpenThread, Matter, and the Zephyr RTOS), which are continuously integrated and redistributed with the SDK.

Release notes might refer to “experimental” support for features, which indicates that the feature is incomplete in functionality or verification, and can be expected to change in future releases. To learn more, see Software maturity levels.

  • Fixed a build error that occurred when building an application for nRF53 SoCs with Simple GPIO Front-End Module support enabled.

Wi-Fi

  • Added experimental support for the nRF7002 DK that includes the nRF7002 companion IC. For more information, see the Developing with nRF70 Series guide.

See Wi-Fi samples for details about how to use Wi-Fi in your application.

Protocols

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

  • Updated the PWM frequency of the pwmleds device from 50 Hz to 125 Hz in applications that run on Nordic Thingy:91.

Note

A known issue was found that concerns modem trace retrieval incompatibility with TF-M (NCSDK-15512): You can either use UART1 for TF-M output or for modem traces, but not for both. This affects applications and samples based on nRF9160.

nRF9160: Asset Tracker v2

  • Added:

  • Updated:

    • The application to use TF-M as the default secure firmware component.

    • Data sampling method. It is now performed when the device detects both activity and inactivity in passive mode, notified by the SENSOR_EVT_MOVEMENT_INACTIVITY_DETECTED event of the sensor module.

    • CONFIG_MODEM_NEIGHBOR_SEARCH_TYPE Kconfig option.

    • Publishing method for GNSS fixes. GNSS fixes are now published in the PVT format instead of NMEA for nRF Cloud builds. To revert to NMEA, set the CONFIG_GNSS_MODULE_NMEA Kconfig option.

    • Forwarding of SENSOR_EVT_MOVEMENT_ACTIVITY_DETECTED and SENSOR_EVT_MOVEMENT_INACTIVITY_DETECTED events by the sensor module.

    • Real-time configurations, which can now configure the upper and lower thresholds for motion detection. You can also configure the timeout after which the sensor reports inactivity. It is now set to 30 seconds.

    • LwM2M schema. To use the new parameters, upload the updated config_object_descript.xml file to AVSystem.

    • The conversions of RSRP and RSRQ. These now use common macros that follow the conversion algorithms defined in the AT Commands Reference Guide.

    • Bootstrapping to be disabled by default. This allows connecting to the default LwM2M service AVSystem’s Coiote Device Management using free tier accounts.

    • CONFIG_DATA_DEVICE_MODE Kconfig option to be a choice that can be set to either CONFIG_DATA_DEVICE_MODE_ACTIVE or CONFIG_DATA_DEVICE_MODE_PASSIVE, depending on the desired device mode.

    • The default sample timeout for sample requests that include neighbor cell searches. The time is now set to 11 seconds.

    • Documentation structure.

  • Fixed:

    • An issue that reports GNSS altitude, accuracy, and speed incorrectly when using LwM2M engine.

    • An issue that caused modem FOTA jobs to be reported as not validated to nRF Cloud.

    • An issue that caused the Memfault event storage buffer to get full, which in turn resulted in lost Memfault events.

  • Removed:

    • CONFIG_APP_REQUEST_GNSS_ON_INITIAL_SAMPLING Kconfig option.

    • CONFIG_APP_REQUEST_NEIGHBOR_CELLS_DATA Kconfig option.

    • CONFIG_EXTERNAL_SENSORS_ACTIVITY_DETECTION_AUTO Kconfig option.

    • CONFIG_MODEM_CONVERT_RSRP_AND_RSPQ_TO_DB Kconfig option.

    • CONFIG_DATA_ACCELEROMETER_THRESHOLD Kconfig option.

    • CONFIG_DATA_ACCELEROMETER_BUFFER_STORE Kconfig option.

    • CONFIG_DATA_ACCELEROMETER_BUFFER_COUNT Kconfig option.

    • SENSOR_EVT_MOVEMENT_DATA_READY event.

nRF9160: Serial LTE modem

    • New #XDFUSIZE command to get the size of the DFU file image.

  • Updated:

    • The application to use TF-M enabled by default.

    • The GNSS service to signify location information to nRF Cloud.

    • The AT response and the URC sent when the application enters and exits data mode.

    • WAKEUP_PIN and INTERFACE_PIN to be now defined as Active Low. Both are High when the SLM application starts.

  • Fixed an issue where the features of the Mbed TLS v3.1 were not enabled by default, which caused the native TLS to not work. The documentation of the Socket AT commands’ socket option numbers was updated accordingly.

  • Removed the software toggle of INDICATE_PIN in case of reset.

nRF5340 Audio

nRF Machine Learning (Edge Impulse)

  • Added configuration of Bluetooth LE advertising providers. The subsystem is now used instead of the *.def file to configure advertising data and scan response data in CAF: Bluetooth LE advertising module.

  • Updated Bluetooth advertising data and scan response data logic. The UUID128 of Nordic UART Service (NUS) is now added to the scan response data only if the NUS is enabled and the Bluetooth local identity in use has no bond.

nRF Desktop

  • Added configuration of Bluetooth LE advertising providers. The subsystem is now used instead of the *.def file to configure advertising data and scan response data in CAF: Bluetooth LE advertising module.

  • Updated:

    • nRF Desktop peripherals to no longer automatically send security request immediately after Bluetooth LE connection is established. The feature can be turned on using CONFIG_CAF_BLE_STATE_SECURITY_REQ.

    • nRF Desktop dongles to start peripheral discovery immediately after Bluetooth LE connection is established. The dongles no longer wait until the connection is secured.

    • Bluetooth advertising data and scan response data logic:

      • The TX power included in the advertising packet is no longer hardcoded, the application reads it from the Bluetooth controller. The TX power is included in advertising packets even if the Bluetooth local identity in use has bond.

      • The UUID16 of Battery Service (BAS) and Human Interface Device Service (HIDS) are included in advertising packets only if the Bluetooth local identity in use has no bond.

Connectivity Bridge

  • Fixed:

    • Missing return statement that caused immediate asserts when asserts were enabled.

    • Too low UART RX timeout that caused high level of fragmentation of UART RX data.

Samples

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

The following changes apply to all relevant samples:

      • Printing of modem domain events.

      • MQTT support for gnss command A-GPS and P-GPS.

      • The nRF Cloud library’s function nrf_cloud_gnss_msg_json_encode() is now used to send PVT location data instead of building an NMEA sentence.

      • Minor logging and function structure improvements.

    • Fixed an issue with connection initialization that would cause delta modem FOTA updates to hang and would require manual reset.

  • Cellular: nRF Cloud REST FOTA sample:

    • Added support for full modem FOTA updates.
