Hello BobO,

Should I use the streamout or pocketout instruction, attached is a copy of the small program,
Should I open a TCP connection every time I send something out?  and do i need to close the connection?
Thanks in advance.

PACKETOUT is UDP, STREAMOUT is TCP.

You can keep the connection open and send more. When you are done sending, close the connection.
