Point this protocol at Traxelio

Point GT02 at Traxelio

  1. 1

    Capture a GT02 fingerprint

    Confirm a binary frame that opens 0x68 0x68 with type 0x10 or 0x1A, not a 0x7878 login.

  2. 2

    Point GT02 at 5022

    Configure only GT02 to TCP 5022. GT02 on 5022 is not GT06 on 5023 or TK102 on 5036.

  3. 3

    Wait for the heartbeat reply

    A 0x1A heartbeat is answered 0x54 0x68 0x1A 0x0D 0x0A. Type 0x10 has no reply byte.

  4. 4

    Prove one GT02 fix

    Send one 0x10 body with flags bit 0 set on 5022 and verify a map point.

What Traxelio surfaces from these packets

GT02 fields Traxelio reads

  • GPS Location
  • Speed
  • Altitude
  • Heading / Direction
  • Street Address
  • GPS Accuracy
  • Ignition Status
  • Odometer / Mileage
  • Engine Hours
  • Battery Level

Still offline after GPS lock

GT02 still not landing

GT02 aimed at the wrong port

GT02 on 5022 is not GT06 on 5023 or TK102 on 5036.

Heartbeat ok, empty map

Type 0x1A only keeps the session. A map point needs type 0x10 with flags bit 0 set.

Sent 0x7878 to 5022

0x7878 login belongs on GT06 5023. This listen wants 0x6868 with type 0x10 or 0x1A.

FAQ

GT02 leftover questions

Does GT02 send Concox 0x7878 frames?

No. GT02 opens 0x68 0x68 with type 0x10, 0x1A, or 0x1C. GT06 families use 0x7878 binary login.

Which type byte plots a GT02 fix?

0x10 plots when flags bit 0 is set. 0x1A is a heartbeat. 0x1C stores ASCII result text and will not move the map.

What reply does a GT02 heartbeat get?

Bytes 0x54 0x68 0x1A 0x0D 0x0A. That exchange is not a map point.

How is the GT02 IMEI packed?

Eight bytes after the power and GSM bytes. Read as hex and drop the leading nibble so 15 digits remain.

Can a GT02 unit run SMS setup or a controlled-action flow?

This dialect is positions only. There is no SMS family on this row.
