modules/app_cellular.py: uses the SIM868's built-in AT-command HTTP(S) client (AT+HTTPINIT/HTTPPARA/HTTPACTION/HTTPREAD) instead of a real ppp0 interface, since the module's GNSS (polled continuously by app_gps.py) and its GSM/GPRS radio share the same physical UART (/dev/serial0) - a pppd/chat dial-up would take over that port entirely and starve GNSS polling. Staying in AT-command mode lets cellular HTTP calls interleave safely through the same serial lock. Only carries small JSON tracking batches, never dashcam video - cellular is far too slow/limited for that, and the modem's HTTP AT interface has too small an internal buffer anyway. Dashcam uploads remain WiFi/Ethernet-only, unchanged. modules/app_upload.py: tracking-batch upload always tries WiFi/ Ethernet first; only on a connection-level failure (not an HTTP error status, which means the server was reached) does it retry over cellular. Exposes last_network_path/cellular_fallback_configured in /api/upload/status; UI shows which path the last batch used. Feature-flagged off by default via new YARIS_CELLULAR_ENABLED/ YARIS_CELLULAR_APN/_APN_USER/_APN_PASS keys in db/upload_creds.env (all blank by default) - has zero effect on the existing WiFi upload path unless explicitly configured. Regression-tested against the real deployed server that normal WiFi uploads are unaffected while cellular stays unconfigured. *** UNTESTED against real cellular hardware - no SIM card was *** available. See docstrings in app_cellular.py and PLAN.md for *** exactly what needs validation once a SIM card is available. Co-authored-by: Copilot <[email protected]>
