The final aim is to build a transmitter and receiver for 802.11p DSRC packets.
The receiver is currently using 802.11a, for testing purposes, but I do have a flowchart they successfully receives 802.11p instead. I've figured out what I need to put in the file source (message binary, not .pcap), but I'm unsure how to translate that from a gr_stream to a gr_message, so I can feed it into the Wifi MAC block. Thanks!
