GpsMarker ASCII on Traccar TCP 5057: $GM type/index, 15-digit IMEI, Tddmmyyhhmmss, N/S E/W packed lat/lon.
TCP 5057.
$GM then type digit.
15-digit IMEI before the T timestamp.
GpsMarker on Traccar TCP 5057 is $GM packed ASCII. GpsMarkerProtocolDecoder matches $GM, a type digit, optional index hex, a 15-digit IMEI, T + ddmmyy/hhmmss, hemisphere letters with degree/minute/frac fields, then speed and course.
Do not confuse with GpsGate $GPRMC on 5026 or Haicom $GPRS on 5063. GpsMarker’s identity is the $GM…IMEI…T packed layout on 5057.
Stock Traccar reference only. Traxelio lists GpsMarker as positions_only.
ASCII must start with $GM — not $GPRMC or $GPRS.
Save APN server hostname/IP and port 5057; reboot.
Pattern requires exactly 15 digits.
Tddmmyyhhmmss plus N/S E/W coords proves the path.
