I have not looked at tunnel_ip_null_mac. I went through the others. What I am trying to do is identify the gnuradio blocks I will need to use to convert a character stream from a file into signals that can be sent across the SMA cable to the rx side, where it can be decoded and written as a character stream back to a file.
I used the gnuradio blocks from the old gmsk implementation (python test script that reads from a file and writes to a file - using the simple_correlator block) in Click to send the stream across the SMA cable, but it does not seem to work. I was having some issues with usrp overrun, but I cleared those problems.
I am assuming that maybe they dont work properly over the cable, so I want to use the blocks in the new gmsk2 implementation. I am not able to identify the blocks i need to put together as a flowgraph to do this to use in Click. I need not have very complex packets. Something simple would do as long as I can get a character stream across.
benchmark_gmsk_tx and benchmark_gmsk_rx calls the gmsk2_demod and gmsk2_mod eventually. I find packet_utils confusing.
Is it possible for me to create a graph of gr_blocks that lets me read a character stream and send it across.
Thanks

Do you understand benchmark_gmsk_tx, benchmark_gmsk_rx and
tunnel_ip_null_mac? If not, what are your specific questions?
