Collapse the two-branch snprintf into a single call so every
detection message includes is_raven (true/false) and raven_fw,
making the format self-describing regardless of device type.
BLE server callbacks run on the NimBLE host task, not the Arduino
loop task. Calling WiFi state changes and delay() from that context
can stall BLE processing or trip watchdogs, and mutating scan
duration creates a cross-task data race.
Fix: callbacks now just set a volatile pending flag. The actual
WiFi/scan changes are applied in loop() where they're safe.
Enable DeFlock mobile app connectivity via BLE GATT notifications,
and desktop host detection via USB serial heartbeat. When a companion
is connected, WiFi AP is disabled to free radio bandwidth and BLE
scan duty cycle is increased for better detection performance.
- BLE GATT server advertising service UUID a1b2c3d4-e5f6-7890-abcd-ef0123456789
with TX characteristic (NOTIFY) for streaming detection JSON
- Chunked BLE notification sender respecting negotiated MTU
- "event":"detection" field added to JSON output for DeFlock parser
- Serial host detection via heartbeat timeout (5s)
- Companion mode: WiFi AP off + scan duration 2s→3s when connected
- Scan interval/duration converted from #define to mutable variables
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
