Hi Thierry, There are three version of bbn code: the original, the douglias version and usrp2 version. These three versions all have these two script. So which version is right for the simple_mac.py
I have modified the simple_mac.py in the original bbn code and it works for the usrp. But it seems that the txpath and rxpath is from the class of usrp_transmite_path and usrp_receive_path, not from the bbn 80211 module. It is like the tunnel.py in the gnuradio directory. I noticed that in 80211_mac.tar.gz, the simple_mac.py's txpath and rxpath use the bbn transmitting and receiving module, which is different from the simple_mac.py in the original version. Do you know these differences?
