James, I suspect that you don't have a working knowledge of python. Python has excellent documentation. Please work through the tutorial and become familar with the python library reference. You can find them here: http://www.python.org/doc/2.5.2/download Please be sure that you fully understand the following line of code. It is the one that builds the packet payload. Do not ask for help about it on this list. It's standard Python and there is absolutely nothing GNU Radio specific about it. send_pkt(struct.pack('!H', pktno) + (pkt_size - 2) * chr(pktno & 0xff)) Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
