Use Auto Transmit/Receive switching (ATR) and see tunnel.py for an example that uses it. (It's a terrible example of a MAC, but does show how to set up something similar to what you want.) No need to stop the flow graphs. Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
