It means that your device connects and disconnects. Depending on the device, it might be expected behavior.

You need to ask your device vendor.
this mean that the problem with the device ???
its not the problem with the device, its choice of a design that they do when creating device client. they can either choose to close connection after sending location message(create new connection for next message), or keep the same connection for next message to be sent. basic networking concepts these
how can i do it ???
You could write some new source code for your device's firmware. But perhaps it would be more trouble than it is worth.
