Hi, I wanted to ask you that if i want to send two independent data streams to two daughter boards mounted on one usrp, wats the command for it. If i want to explicitly send data1 to sub(0,0) and data 2 to subdev(0,1) SIMULTANEOUSLY..then how do you do it? I have read few examples but im not able

Hi George, I was looking for BBN & USRP2 information at the list when I saw your message. I'm interested on get interoperability with 802.11 cards in monitor mode, but I still haven't had success. Could I make you some short questions? - Which modification did you do to the transmission filter?
