I do not remember specifically what I used at the command line to get the two USRP2s to talk to each other. I know I had it working for 1 and 2 Mbps. I think something must be messed up with the spreading sequence. George, wasn't there a discussion on that sometime ago? I remember there were plots being exchanged on the mail list.

It was on a project I worked on a year ago so its a little foggy.

Sorta random, the guy who wrote a lot of the SPAN code ended up in the same lab I'm in now.

Thanks George for your inputs.

I have closely been monitoring cgran website. However, every project seems
to be focusing on how well one can use USRP1 or USRP2 as 80211b receiver.
But my goal is to communicate between two USRPs (whether USRP1s or USRP2s)
using bbn 80211b code.

>From the previous discussions on this forum, it seems that quite a few
people were able to communicate and decode packets correctly using two
USRP2s and usrp2_version bbn 80211b code. I am trying to know whether the
usrp2_version code needs any modification or specific command line

No problem!  Maybe check the date/time of a post to the board in which someone reported success and try to grab a version from SVN relevant to that timestamp.  Maybe something changed in between breaking something.  I have two USRP2s hooked up, I can try the code out myself tomorrow.
