Hello all, I've created a custom out of tree source block which listens for UDP packets and does different things depending on the received packet. It is connected to a NULL sink because I haven't quite worked out how to make a standalone UDP Server (and I've found the tutorials to be very confusing unfortunately).
When the packet is "stop", I would like the flowgraph to be stopped. I've seen from researching different forums that if *-1* is returned, the flowgraph is supposed to stop but I only find that this stops my block from running, the rest of the flowgraph continues running. Is there not a simple command which I can use to kill the whole flowgraph? An alternative solution I tried to implement was to access these values using a *vector sink* block and the .data() method from the top_block.py This didn't seem to work correctly as Python's UDP calls block. Thank you, hopefully I've made this post properly. I'm quite new to programming with GNURADIO. David
