I'm trying to create a basic GNURadio flow graph that will transmit a short message in order to receive an appropriate reply back.
I currently have the following flowgraph:
I have a program that sends UDP messages to the UDP Source and receives the UDP messages from the UDP Sink
I am able to receive a message from the UDP Sink only if I loop the message I send from the program a couple of times (about 250 at least). Because of this I receive multiple repeated messages, and I wish to receive just one. One way of solving this is through programming, but it is proving to be quite challenging (but should be possible). Is there a proper way through altering the flow graph parameters with which we can transmit a message without looping or repeating?
