GT06 Devices disconnects after sending Information Transmission Packet(0x94)

Sreekantha year ago

Some of my devices are getting connected and disconnects with in 1 second,
After 5 seconds it connects back and disconnects again

This happens when device send Info packet (0x94) with voltage. and the error I see is error - Connection reset - SocketException (...)
I tried to poll to the demo4.traccar.org server (Device : 867440062419957) and it is same over there also.

This is happening with multiple devices randomly.

Is this a device issue or Bug ?

Below are the logs

Looks like device disconnects from the server. Maybe it's expecting some response, but doesn't receive it.

Sreekantha year ago

As per protocol document server response is not required for Info packet.

But after some hours it will send location data.

It will start polling location data for some time and then same disconnections happens again.
If we observe the vehicle didn't stop , it was moving with speed of 18.9 and suddenly goes to connected and disconnected state
And we don't receive any GPS data

This is happening with multiple devices randomly.

Unable to figure it out why this happening , Device issue ?

Hi Anton Tananaev,

Can you please check above comment and let me know if it is a device issue or issue with traccar or network ( same happening with demo4.traccar.org server also)

Anton Tananaeva year ago

I already commented above.
