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?

Thanks

Chen
