ESP32-S3 CSI requires DATA frames (LTF extraction) — MGMT-only filter silences CSI entirely on this chip revision because management frames (beacons, probe req/resp) contain no extractable LTF. Root cause: CSI yield=0pps despite WiFi connected and RSSI healthy. Fix: WIFI_PROMIS_FILTER_MASK_MGMT → WIFI_PROMIS_FILTER_MASK_ALL. Verified on Heltec LoRa V3 (ESP32-S3FN8 rev v0.2, Zyxel_D631 AP). Post-fix yield: 5-8 pps stable. Note: On busy networks (100+ data frames/sec) this may cause WiFi HW interrupt storms that crash Core 0. Low-traffic networks are safe. |
