## Notes
|
|
|
|
- Adaptive threshold varies by environment; 0.001-0.01 is a good starting range
|
|
- NVS keys: `send_rate`, `tx_power`, `adaptive`, `threshold`, `ble_scan`, `target_ip`, `target_port`, `hostname`, `boot_count`, `csi_mode`, `hybrid_n`, `auth_secret`, `flood_thresh`, `flood_window`
|
|
- EVENT packets now include sensor hostname: `EVENT,<hostname>,motion=... rate=... wander=...`
|
|
- ALERT_DATA format: `ALERT_DATA,<hostname>,<deauth|disassoc>,<sender_mac>,<target_mac>,<rssi>` or `ALERT_DATA,<hostname>,deauth_flood,<count>,<window_s>`
|
|
- STATUS fields: `uptime=`, `uptime_s=`, `heap=`, `rssi=`, `channel=`, `tx_power=`, `rate=`, `csi_rate=`, `hostname=`, `version=`, `adaptive=`, `motion=`, `ble=`, `target=`, `temp=`, `csi_count=`, `boots=`, `rssi_min=`, `rssi_max=`, `csi_mode=`, `hybrid_n=`, `auth=`, `flood_thresh=`
|
|
- PROBE_DATA format: `PROBE_DATA,<hostname>,<mac>,<rssi>,<ssid>`
|
|
- Probe requests deduped per MAC (default 10s cooldown, tunable via PROBERATE)
|
|
- mDNS service: `_esp-csi._udp` on data port (for sensor discovery)
|
|
- HOSTNAME command: `HOSTNAME <name>` sets NVS + mDNS, `HOSTNAME` queries current
|
|
- **ESP32 limitation:** Promiscuous mode (deauth/probe detection) disabled — breaks CSI. Works on ESP32-C6+.
