What Is a GPS Tracker Communication Protocol?
A communication protocol is the rule set a tracker uses to send position records to a server over TCP/UDP. Open protocols let you integrate any platform.

A GPS tracker communication protocol defines how the device packages and sends data — IMEI, time, coordinates, speed, heading, status bits — and how the server should reply (acknowledgement, commands). FOFN trackers use an open TCP/UDP protocol so platform integrators, Traccar/Flespi users and OEM partners can parse data without proprietary lock-in. Basic protocol details are public; the full spec is available on request.
TCP/IP vs UDP Protocol
TCP is connection-oriented and confirms delivery — best when every record matters. UDP is lighter and faster — good for high-frequency reporting on bandwidth-limited networks. FOFN supports both.
What a Record Contains
Typically: IMEI (device ID), timestamp, latitude, longitude, altitude, speed, course, satellites, and status flags (ignition, power, input/output). Extended records add fuel, CAN, temperature and events.
Open Protocol and Integration
Because the protocol is open, you can integrate FOFN trackers with your own GPS platform, a third-party telematics system, or Traccar/Flespi without middleware. Request the full documentation to start.
