OK, a small succes for now.
With the fb IP_Control, it is possible for me to sent a string to a predefined IP address.
I'm starting the transfert by setting IP_C.C_ENABLE to TRUE.
For testing, I sent an UDP string to my pc, where an app "UDP Client Server" is running.
However, as long as C_ENABLE is TRUE the same string is transfered again and again.
How can it be adapted so that the transfer stops after 1 transfer?
