Firmware (main.cpp): adds a line-based CMD:* protocol on the same
USB-CDC port that already streams live detection JSON, so Flask can pull
state without re-flashing:
- CMD:STATUS emits {"event":"status",...} with det count,
SPIFFS state, free heap, uptime, channel
- CMD:VERSION emits firmware identifier + compile-time constants
- CMD:DUMP_LIVE streams the in-RAM detection table as replay
JSON lines, then a replay_complete sentinel
- CMD:DUMP_PREV same, but reads /prev_session.json from SPIFFS
(parses the CRC envelope and the embedded array)
- CMD:CLEAR_LIVE wipes fyDet[] and dirties the autosave
- CMD:CLEAR_PREV deletes /prev_session.json and any /session.tmp
Implementation:
- Minimal string-aware JSON object reader (string-aware brace counter,
backslash handling) lifts entries from the SPIFFS array one at a
time without slurping the whole file
- jsonGetString / jsonGetInt field extractors over flat objects
- emitReplayDetection() reuses the existing Flask schema and adds
replay / replay_source / detection_count / device_first_ms /
device_last_ms so the host can tell historical from live
- serialCmdTick() runs once per loop() and only acts on completed
lines — non-blocking and safe alongside the live detection path
- dualPrintf buffer bumped 384 → 1024 B to fit the longer replay line
(and to remove a latent truncation risk on a long-SSID live line)
Flask (api/flockyou.py): turns the protocol into REST endpoints and
ingests replayed detections without confusing them with live ones:
- flock_reader now dispatches {"event":"status"|"version"|"clear"|
"replay_complete"|"error"} responses to threading.Event slots, and
routes {"replay":true,"detection_method":...} lines through a new
add_replay_detection_from_serial() that skips GPS temporal matching,
flags timestamp_source="device_replay", and merges into an existing
fresher live entry instead of overwriting it
- send_command(cmd, response_event_name, timeout) serializes one
command at a time and blocks until the matching event arrives
- new endpoints: /api/flock/{status,version,dump_prev,dump_live,
clear_prev,clear_live}
Verified: pio run completes clean (RAM 19.1%, flash 12.0%); flockyou.py
passes py_compile. README documents the protocol, the per-event shape,
and the canonical post-wardrive dump_prev → clear_prev workflow.
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
