Hi, I don't have USRP but just USRP2. I think you should try this part of code : svn co https://www.cgran.org/cgran/projects/bbn_80211/branches/usrp2_version there are the bbn_80211b_rx.py & bbn_80211b_tx.py files wich work fine for many of us between 2 USRP2. I used these options: ./bbn_80211b_tx.
