Point Opengts at Traxelio

  1. 1

    Capture an Open GTS fingerprint

    Confirm HTTP query parameters that embed $GPRMC with A/V.

  2. 2

    Point Open GTS at 5159

    Configure only Open GTS to HTTP port 5159. Open GTS HTTP+$GPRMC is not Outsafe JSON device on 5200.

  3. 3

    Bind the Open GTS device id

    Complete the Open GTS login or id path on 5159 before expecting map points.

  4. 4

    Prove one Open GTS fix

    Send one coordinate-bearing Open GTS frame on 5159 and verify a map point.

Still offline after GPS lock

Opengts still not landing

Open GTS aimed at the wrong port

Open GTS HTTP+$GPRMC is not Outsafe JSON device on 5200.

Open GTS session up, empty map

On 5159, Open GTS may bind without coordinates. Wait for a position-bearing frame matching HTTP query parameters that embed $GPRMC with A/V.

FAQ

Opengts leftover questions

Does Open GTS send Concox binary frames?

No. Open GTS on this page is HTTP query text that embeds a $GPRMC NMEA sentence with A or V. Concox GT06-class devices use binary frames.

Which query keys does a GPSLogger-style Open GTS hit use?

Hits that use id plus gprmc. GeoTelematic gprmc.war uses acct plus dev plus gprmc. A wrong key name drops the sentence.

Why does a $GPRMC sentence land on GeoTelematic but miss on 5159?

Time on 5159 is hhmmss. A fractional second such as 143013.0 is a known miss. The XOR checksum must also match.

Is Open GTS a GeoTelematic product or a Traxelio-only dialect?

Open GTS is GeoTelematic's open-source stack. Traxelio maps the HTTP+$GPRMC dialect on 5159. We do not run gprmc.war.

Can a phone replace a dedicated tracker on Open GTS?

GPSLogger and similar apps can emit HTTP+$GPRMC. This dialect is positions only: you get a map fix, not SMS setup or a controlled-action flow.
