Mathieu MoranandCopilot f17c5c8681 Phase 12: remove phone-relay dashcam upload feature
Removes the phone-relay feature entirely per the Phase 11 finding
that it hit a fundamental phone-OS limitation (a browser page can't
route WiFi and cellular traffic simultaneously, no code fix possible)
- see PLAN.md for the full test writeup.

- app.py: dropped /api/dash/pending, /api/dash/file/<path>,
  /api/dash/relay/config, /api/dash/relay/heartbeat,
  /api/dash/relay/stop, /api/dash/relay/mark_uploaded routes and
  their now-unused imports (os, send_file, abort, safe_join).
- modules/app_upload.py: dropped list_pending_dashcam_files(),
  relay_heartbeat()/relay_stop()/is_relay_active(),
  RELAY_LEASE_SECONDS/_relay_lease_until, and the relay-lease check
  inside _upload_dashcam_files()/get_status(). Kept the chunked
  upload protocol, dashcam_hash_cache/_hash_dashcam_file() (still
  used by the Pi's own background uploader), and DASHCAM_CHUNK_SIZE -
  none of that was relay-specific.
- templates/dash.html: removed the 'Relay via phone' card.
- static/js/dash.js: removed all relay JS (relayOneFile,
  fetchChunkWithRetry, uploadChunkWithRetry, heartbeat timers,
  pending-file list rendering).
- server/app.py: removed the CORS after_request hook, added solely
  for the phone's cross-origin browser calls (the Pi's own Python
  requests-based client was never subject to CORS).
- readme.md: dropped the phone-relay feature bullet, updated the
  project-status blurb to explain the removal + point at the planned
  native Android app as the real fix for that use case.
- PLAN.md: marked Phase 12 done with a verification writeup.

Verified: py_compile on all touched Python files, node --check on
dash.js, grepped all touched files for any leftover relay/RELAY
reference (none), and smoke-tested by importing app.py + hitting it
with Flask's test client - app starts cleanly, every relay route is
gone from url_map, and both / and /dash still render HTTP 200 with
zero 'relay' occurrences in /dash's HTML.

yaris-obd 🚗📡

A Raspberry Pi 3-based OBD-II + GPS tracker for my 2013 Toyota Yaris — reads live vehicle data over USB, tracks position with a SIM868 GNSS/GSM HAT, and serves it all from a local web UI you can pull up on your phone by connecting to the car's own WiFi hotspot. Fully usable offline: no internet needed in the car, offline map tiles included. Also handles pulling dashcam footage off a USB dashcam for local/remote backup.

UI

Features

  • 📊 Live OBD-II data (speed, RPM, DTC codes) over a cheap USB ELM327-compatible adapter
  • 🛰️ Real GPS tracking via a Waveshare SIM868 GNSS/GSM/Bluetooth HAT, plotted live on an offline Leaflet map (pre-cached map tiles — no internet needed in the car)
  • 📶 Self-hosted WiFi hotspot so you can load the web UI on your phone from inside the car, with automatic fallback to your home WiFi when in range (http://yaris.local — no port number)
  • 🎥 Dashcam file retrieval — detects a USB dashcam automatically (any brand/folder layout, no hardcoded device path), copies its footage locally, verified against real hardware
  • ☁️ Remote upload — a self-hosted server (Flask + Postgres, server/) receives trip/GPS logs and dashcam footage over the internet (via Cloudflare Tunnel or a plain port-forward). Dashcam videos upload in resumable 40MB chunks (works around tunnel body-size limits and keeps the Pi's memory footprint flat regardless of file size); a UI toggle can pause dashcam uploads independently while trip logs keep syncing
  • 🗄️ Local SQLite trip logging, retried/synced to the remote server with automatic backoff
  • 🔌 Runs fully headless as a systemd service, autostarting on boot

Part Notes
Raspberry Pi 3 Model B Web UI host + hotspot
Waveshare SIM868 HAT GNSS (GPS) + GSM/GPRS, unused Bluetooth
USB OBD-II adapter PL2303-based, ELM327-compatible (originally Bluetooth, switched to USB)
USB dashcam Any brand — detected as generic USB mass storage
2013 Toyota Yaris The patient

See PLAN.md for full hardware bring-up notes (SIM868 jumper/UART setup, antenna gotchas, etc.) and the detailed project history.

Getting started

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python3 app.py

The app serves on http://<host>:5000. On the Pi it also runs as a systemd service (see deploy/) and is reachable with no port number at http://yaris.local once the mDNS + port-redirect setup described in PLAN.md is installed.

For the remote server (receives trip logs + dashcam uploads), see server/README.md.

Project status

This project was revived after a couple of years on the shelf. The first 11 planned phases are done and the full pipeline — OBD/GPS logging, offline web UI, WiFi hotspot, dashcam retrieval, and remote upload — has been verified against real hardware end-to-end, including a full real dashcam import and upload run. A phone-relay upload feature was built and tested but ultimately removed: real-world testing showed it hit a fundamental phone-OS limitation (a browser page can't use WiFi and cellular simultaneously), so it couldn't actually deliver on its "upload from the road without the Pi's slow WiFi" goal — see PLAN.md for the full writeup. That capability is now planned as a native Android app (further down the roadmap) instead. Only the SIM868 cellular fallback (for uploading while out of WiFi range) remains untested (no SIM card available yet). Full phase-by-phase history and the current roadmap (dashcam/video file browsers, OBD hardening, power-loss resilience, trip history, alerts, and more) are in PLAN.md.
