GPS location does not update

Title: GT06 device connects but GPS location does not update – Traccar 6.16.0

Hello Traccar team,

I am using Traccar version 6.16.0 with a GT06 GPS tracker.

The device connects successfully and sends packets every 5 minutes, but its location is not updating. Traccar keeps reporting the same old position and timestamp.

Device details:

• Protocol: GT06
• Device ID / IMEI: `8699250xxxxxxxxx
• Traccar version: 6.16.0
• Server timezone: Asia/Kolkata

Repeated position log:

id: 869925075267805
time: 2026-10-17 22:09:38
lat: 26.21645
lon: 85.28920
course: 0.0

Received packets:

78780a1304060400020049b49e0d0a
79790008940004e3004b62df0d0a

These packets continue arriving, but the reported GPS timestamp and coordinates remain unchanged.

Could someone help me identify these packets and explain why the device is not sending updated GPS positions? Is this a tracker configuration issue or a GT06 protocol compatibility issue in Traccar 6.16.0?

I can provide additional debug logs if needed.

Thank you.

The device continues connecting and sending packets, but Traccar keeps reporting the same coordinates and old GPS timestamp.

Could you please confirm whether these packets contain GPS location data? If not, is there a way to determine why the tracker is not sending location packets?

Thank you for your help.

Your device is not sending any location data!!!

I understand. The device is connected and sending data packets every 5 minutes, but no new GPS location is being received.

Could you please help me identify the packets and confirm whether the tracker is sending only heartbeat/status data? How can I troubleshoot this issue further?

Thank you.
