Low-confidence mac_prefix_mfr hits no longer update fyLastDetTime/fyLastHB,
preventing them from keeping the heartbeat alive after a high-confidence
device leaves range. Bump FYDetection::method from 24 to 32 bytes so
"mac_prefix_soundthinking" (23 chars) has headroom.
- fyPromotePrevSession now reads session.json, writes to prev_session.json,
then deletes the original — SPIFFS.rename() silently fails on ESP32
- prior session KML export: added style defs, raven metadata, error handling,
moved file validation before response stream init
- reduced auto-save interval 60s → 15s, added 5s quick-save on first detection
Address Copilot review: contract manufacturer OUIs (Liteon/USI) are now
in a separate flock_mfr_mac_prefixes[] array emitting "mac_prefix_mfr"
as the detection method. SoundThinking/ShotSpotter gets its own array
and "mac_prefix_soundthinking" method. Low-confidence detections (mfr
OUIs) suppress buzzer/heartbeat but still emit JSON events so consumers
can apply their own thresholds.
Expand MAC prefix detection with entries sourced from:
- Flock WiFi (Liteon/USI): f4:6a:dd, f8:a2:d6, e0:0a:f6, 00:f4:8d,
d0:39:57, e8:d0:fc — contract manufacturer OUIs (Liteon Technology and
USI/Universal Scientific Industrial) identified via the OUI-SPY firmware
ecosystem table and cross-referenced against the IEEE OUI registry.
These manufacturers produce Flock Safety's WiFi-enabled camera hardware.
- Flock Safety direct: b4:1e:52 — registered directly to "Flock Safety"
in the IEEE OUI database (MA-L assignment). This is their own prefix
rather than a contract manufacturer's.
- SoundThinking/ShotSpotter: d4:11:d6 — registered to "SoundThinking Inc"
(formerly ShotSpotter) in the IEEE OUI database. Their acoustic gunshot
detection sensors use BLE for local diagnostics and provisioning.
Complete rewrite of standalone Flock-You firmware:
- Remove WiFi promiscuous mode, all detection is now BLE-only
- Add web dashboard served on AP "flockyou" at 192.168.4.1
- GPS wardriving via phone browser Geolocation API
- SPIFFS session persistence with auto-save every 60s
- Prior session tab (PREV) survives reboots
- KML export for Google Earth (current + prior session)
- JSON/CSV export with GPS coordinates
- Serial JSON output for Flask live ingestion
- Crow call boot sounds with detection/heartbeat alerts
- 200 unique device storage with FreeRTOS mutex
- Flask app: add KML import endpoint, GPS data handling
- Update platformio.ini with AsyncWebServer, ArduinoJson 7, SPIFFS partition
- Rewrite README to reflect current functionality
