Hi,

Another must be a server and anothere client. Client makes connection to the server and if server accepts client, connection is initialized.
Basically you create server that listens some TCP/IP port and then you create client that connects that TCP/IP port.

Hi,

You can use our DLMS components. You will find them from GitHub:
https://github.com/gurux

DLMS is very complicated protocol. If you are interested all data is described in standards. You can study them. It's not easy to start describe structure of the packet.
