Not enough readable bytes

Getting error after the device gets connected to the server. I am using 5023 port (GT06).
Error Message log says:

Is there some issue with the client sending the request?

It probably means that one of the messages has incorrect length value.

Next time, it came as

No entry got created in positions table. Devices table got updated and in the map it is showing at lat: 0 and long:0

Needed help to understand this.

This time there is no GPS data. Look, I recommend you to search forum before asking for help. It has been discussed multiple times before.

Was wondering if im doing anything wrong as I am trying for the first time.
Will go through the forum once. Thanks a lot
