Thanks Mariano!
I am trying to test it out now. When I run the rftest (after building it) I
get a '.' output every second or so. I don't get any errors or anything.
So then I thought id follow the wireshark guide to check packet output. I
have a transmitter to generate packets. Regardless of getting the channel
correctly, whether I dump to a pcap file or pipe to wireshark I end up
getting a "protocol 230 unknown" error. So it seems like the global pcap
header identifies the protocol as 230, which wireshark does not recognize.
Have you or anyone else seen this error before? I'm just trying to test
things out without tampering with the FW first since it was pre-flashed.
Thanks a bunch!
