Can you please guide.

Do you have the HEX sample? Have you tried master version?

I took it on 10th Aug from the master branch. Below is the hex

This sample doesn't work even on older version of Traccar.

But it doesn’t come in 4.14

Please provide a log fragment.

I see the same problem. I think you should probably provide some commentary.

commentary means ?

what is your exact device model?

FMB920

I asked to provide a log fragment from 4.14 where it is working.

What could be the event from this device to produce this error? I have FMB920 too in a server since 4.10 and now 5.3 traccar version, and didn't found any warning or error from this device

We have checked the data and found that the given packet is not complete. This may have happened due to larger size of data packet. The maximum limit for a device to send data 1280bytes. But due to restriction from operator, the device can send up to 1kb at once.
So, there are chances that the remaining data is pushed in the second packet.
