Auto Protocol Detection
The gateway detects protocols from packet signatures. Mismatched ports are logged as warnings. GT06 supports Type A (0x7878) and Type B (0x7979) framing.
IMEI Validation
Only registered devices are accepted. Unknown IMEIs are queued for admin onboarding. JT808 uses 6-byte BCD terminal IDs.
Data Pipeline
Gateway → Redis Streams → Worker → TimescaleDB → WebSocket. Position data includes analytics (mileage, engine hours). Pre-aggregated summaries feed reports.
Sensor Auto-Discovery
New I/O parameters are auto-registered in detected_attributes. GT06 calibrates battery/GSM to %. Teltonika maps 60+ I/O element IDs.
Command Delivery
API → Redis pub/sub → Gateway → TCP. GT06 uses 0x80 frame, Teltonika Codec 12 (0x0C), JT808 uses 0x8105 / 0x8103. Status: pending → sent → delivered.
JT/T 1078 Video Telematics
Split architecture: Gateway handles signaling (0x9101–0x9306), LKM media server ingests RTP on ports 6801/6802 and outputs HTTP-FLV/WS-FLV on 8088. Dashboard streams via mpegts.js. Supports live multi-channel, historical playback (1×–16×), and PTZ control.
