Hello,
I'm using Traccar with Teltonika devices and protocol.
I send a packet to my host via Packet Sender in which I put a request found in the logs (raws in hexadecimal format).
The result is mysterious : on traccar, the devices appears in green ("Online") and instantly disconnects. But the other big problem is that no information appears on the server. You should have a look at the log to understand what is happening.

As you see here, when I send a request to the server, it always do like this
1 --> CONNEXION
2 --> RECOGNIZE IMEI AND DISPLAY "Online" on Traccar for 1 second
3 --> IMMEDIATELY DISCONNECT
Can you tell me why it is disconnecting? I didn't find similar topics on your forum. I read the teltonika protocol decoder but there is nothing strange.
It's a problem because when I want to send location request, no informations display on the server, I think it's related to this disconnexion problem.
I followed your codec guide, is the length of the request important to respect? Because my logs of devices have always 4 times longer characters than your model on guide.

Why is that so different?
