Quick answers

Stock Traccar port?

TCP 5022.

Position type?

MSG_DATA 0x10.

Heartbeat?

0x1A with 0x54 0x68 0x1A ACK.

GT02 on Traccar TCP 5022 is length-field binary. Gt02ProtocolDecoder skips a 2-byte header, reads type MSG_DATA (0x10), MSG_HEARTBEAT (0x1A) — replies 0x54 0x68 0x1A 0x0D 0x0A — or MSG_RESPONSE (0x1C).

0x10/0x1A — not GT30 $$ text

Do not confuse with GT30 $$ NMEA-ish text on 5131 or GS100 GL/GS100 on 5223. GT02’s identity is the 0x10/0x1A/0x1C type set on 5022.

Catalogue stance

Stock Traccar reference only. Traxelio lists GT02 as positions_only.

Setup walkthrough

  1. 1

    Confirm binary GT02

    Hex must show length-field framing and type 0x10/0x1A — not $$ GT30 text.

  2. 2

    Aim host at TCP 5022

    Save APN server hostname/IP and port 5022; reboot.

  3. 3

    Keep heartbeats alive

    0x1A ACKs prove the session path while waiting for 0x10 fixes.

  4. 4

    Send MSG_DATA

    Type 0x10 is the coordinate path.

Common troubleshooting

Only heartbeats

0x1A alone yields no map points — wait for 0x10 data.
