Connected CIP adapter

[ASolchen]

Just out of curiosity, is it possible to use the CIPDriver to connect using "connected" method? I haven't read the EIP docs, but did take a wireshark capture of a PLC connecting and controlling an EIP Stepper driver. It is pretty interesting. It seems to connect using TCP on port 44818 at first and then switches to UDP on port 2222 and sends data / get responses at the RPI intervals. I looked through the socket_.py file and see it only uses 'socket.socket(socket.AF_INET, socket.SOCK_STREAM)' A UDP socket would be like 'socket.socket(socket.AF_INET, socket.SOCK_DGRAM)' so I'm guessing it is not possible at this point. Is this correct? Would this be a lot of work to add?

Also if anyone is interested in the .pcapng capture file, let me know. Here's how it looks:
