Protocol Hub

Welcome to the Protocol Hub — comprehensive documentation for communication protocols used in fleet management and telematics systems.

Overview​

The Protocol Hub documents the communication protocols used between GPS devices, vehicle systems, and fleet management platforms. This includes standard protocols, proprietary protocols, and emerging standards.

Protocol Categories​

Standard GPS Protocols​

Widely adopted protocols supported by multiple device manufacturers.

  • GT06 / GT02 - Popular protocol for Chinese GPS trackers
  • TK103 - Common protocol with many variants
  • H02 - Protocol used by many entry-level devices
  • Meitrack - Protocol for Meitrack devices

Proprietary Protocols​

Vendor-specific protocols requiring custom implementation.

  • Teltonika - Binary protocol with codec support
  • CalAmp - Protocol for CalAmp devices
  • Syrus - Syrus device protocol

Vehicle Communication Protocols​

Protocols for communicating with vehicle systems.

  • OBD-II - On-board diagnostics standard
  • CAN Bus - Controller Area Network
  • J1939 - Heavy-duty vehicle communication
  • J1708 - Older heavy-duty vehicle protocol

Network Protocols​

Protocols for data transmission over networks.

  • HTTP/REST - Web API communication
  • MQTT - Lightweight messaging for IoT
  • WebSocket - Real-time bidirectional communication
  • TCP/UDP - Transport layer protocols

Protocol Implementation​

Server-Side Implementation​

Guidelines for implementing protocol parsers on fleet management servers.

Device-Side Implementation​

Information for developers creating custom firmware.
