Hi

We are also working on the same set up as you people did except that we  
are  
using USRP N200. We were trying to make two USRPs communicate using  
benchmark\_tx/rx.py. When trying to run benchmark files,we are getting an  
error saying " Failed to automatically set up a USRP device". Can you  
help  
us out that why are we encountering this problem?

I believe somebody has ported the benchmark rx and tx examples for uhd.  
Anybody know where these can be found?

Hi Josh,

I would be really interested in the uhd versions of benchmark rx and tx  
as  
well.

I came across this code from Andrew back in March.  
[http://lists.gnu.org/archive/html/discuss-gnuradio/2011-03/msg00256.html](http://lists.gnu.org/archive/html/discuss-gnuradio/2011-03/msg00256.html)  
Please see attachment in the linked email.

Unfortunately I think there are a lot  
of inconsistencies with UHD\_003.001.002

Do you know if there is an updated version of that? Was Andrew’s code  
ever  
published to git?

Thanks!  
Jim
