Connect your tracker

Enter the tracker IMEI first, then verify your email and continue setup.

Quick answers

Stock Traccar port?

TCP 5005.

Common fixes?

$GPRMC / $GPGGA / $TRCCR / QZE.

Sibling?

Not T57 *T57# on 5155.

T55 on Traccar TCP 5005 is a multi-pattern NMEA hub. T55ProtocolDecoder accepts $G[PLN]RMC, $G[PLN]GGA, $G[PLN]GLL, $GPRMA, $TRCCR, $GPIOP, QZE,, $PUBX, $GPTXT,NET, $ID,GPSE, plus $PGID/$DEVID identity starts.

Broad $ family on 5005 — not T57 *T57#

Do not confuse with T57 *T57# on 5155. T55’s identity is the multi-$ NMEA/QZE hub on 5005.

Catalogue stance

Stock Traccar reference only. Traxelio lists T55 as positions_only.

Setup walkthrough

  1. 1

    Confirm $ or QZE capture

    ASCII should show $GPRMC/$TRCCR/QZE — not *T57#.

  2. 2

    Aim host at TCP 5005

    Save APN server hostname/IP and port 5005; reboot.

  3. 3

    Send one A-validity RMC

    Classic RMC A-fix proves the common path.

  4. 4

    Optional $GPIOP power

    Power/battery sentences are siblings, not replacements for RMC.

Common troubleshooting

Sent to 5155

*T57# will not match T55 multi-$ patterns. Move to 5005.

Only $GPIOP

I/O/power without RMC/GGA yields no coordinates.
