Point T55 at Traxelio

  1. 1

    Capture a T55 fingerprint

    Confirm a $GPRMC / $TRCCR / QZE, line, not a Hunter PRO >id< wrap and not *T57#.

  2. 2

    Point T55 at 5005

    Configure only T55 to 5005. T55 on 5005 is not Hunter PRO on 5116 or T57 on 5155.

  3. 3

    Do not wait for OK1 by default

    OK1 is sent only when ACK is enabled on that unit. A parsed A-status RMC is enough.

  4. 4

    Prove one T55 fix

    Send one $GPRMC whose status is A on 5005 and verify a map point.

gps.traxelio.com:5005 TCP

Replace {password} with the tracker PIN or password.

Still offline after GPS lock

T55 still not landing

T55 aimed at the wrong port

T55 on 5005 is not Hunter PRO on 5116 or T57 *T57# on 5155.

Session up, empty map

RMC status must be A. A V status will not plot. $GPIOP alone reuses the last point.

Only $GPIOP, no coordinates

$GPIOP stores power and battery on the last point. Send one A-status RMC or GGA for a map fix.
