Hi, I'm trying to understand some behavior with GT06 devices on our self-hosted server (Traccar 6.14.4).
Every device on our server follows the same cycle:
- Connect → login (0x01) → server replies (ACK)
- Status (0x13) → server replies (ACK)
- Device sends an extended
7979-header packet, protocol 0x94 (MSG_INFO) — e.g. 79790008940009ce020c101f0d0a
- No reply is logged from the server for that specific packet
- ~1-2s later:
Connection reset - SocketException, disconnect, then immediate reconnect — repeating every ~10-15s
This happens identically across all 4 of our device IMEIs, not just one unit.
Is a server reply expected for MSG_INFO/0x94 packets? Could a missing ACK for this message cause the device firmware to reset the TCP connection? Happy to share the full log, device model, or a pcap if that helps. Trying to figure out if this is normal GT06 clone behavior or something we can fix on our end.
Have you checked against the documentation?
Hi Anton,
Yes, I have checked the documentation.
Recently I have tried configuring the device on demo.tracccar.org .
But unfortunately it is not sharing the latest live tracking. Device sends status information, but not GPS coordinates. Everything works on SMS, but not on Web.
I tried checking this link below and sending the command fix060s***n123456 but to no reply.
https://www.traccar.org/clones/
The GPS device is Concox GT06.
Is there anything I still need to do? How to get the live tracking?
So you checked the documentation and what's the verdict?
