Changelog

This release is based on the nRF Connect SDK release v3.4.0.

• Added:

  • nRF Edge AI Observability Library with built-in metrics for tracking model performance at runtime, together with a host script for decoding collected metrics.

  • Data forwarder sample application.

  • Data forwarder host tool for receiving, decoding, and visualizing sensor data from the data forwarder sample.

  • Optional model observability in the WW KWS application through the nRF Edge AI Observability Library, enabled with the CONFIG_MODELS_OBSERVABILITY Kconfig option.

• Updated:

  • In the Hello Edge Impulse sample application, renamed the Kconfig option from CONFIG_EDGE_IMPULSE_PATH to CONFIG_EDGE_IMPULSE_MODEL_PATH.

  • The keyword spotting stage in the WW KWS application now uses class labels provided by the generated model.

  • Bundled Axon models are recompiled with a newer version of the Axon NPU compiler.

• Deprecated the Edge Impulse data forwarder sample application. This sample will be removed in the next release. Use the Data forwarder sample instead and enable the CONFIG_DATA_FWD_PROTO_ASCII_MODE Kconfig option for Edge Impulse CLI compatibility.
