When does this happen?

IF WiFi CSI-based human sensing project fails to capture frames or is dismissed as fake due to hardware incompatibility.

How others solved it

THEN Verify that the hardware supports CSI (e.g., ESP32-S3 with native promiscuous mode, Intel 5300 with modified firmware, Atheros AR9580 with patches). Flash the provided firmware from firmware/esp32-csi-node/ using ESP-IDF, run the Rust aggregator to receive live CSI frames, and confirm amplitude variance when a human body moves near the antenna. Follow the step-by-step tutorial for exact flashing and verification steps.

Use ESP-IDF's esp_wifi_set_csi_config() to enable CSI capture (MIT-licensed; see tutorial for full setup).
