Re: [Discuss-gnuradio] connect USRP-2921 to gnuradio

[mohamid92]

Hello again and sorry for annoying

I did all the step mentioned and installed gnuradio

But again am still not able to connect to USRP 2921

I AM using VMware , I detect the USRP in Windows but when I uhd_usrp_probe args=”addr=192.168.10.2” still cant detect it .

: LookupError: KeyError: No devices found for -----> 
Device Address: 
    addr: 192.168.10.2 

 

I can ping the host and USRP ip but cant detect the UHD ?

Hi Mohamed,

UHD 3.5.5, which you seem to be using, is so very old that it lacks
crucial features. You should definitely update your UHD version.
I assume you're using Ubuntu 14.04 (they are the only ones who still
ship this old UHD), so please

sudo apt-get remove uhd-host libuhd003 gnuradio

and use pybombs to build UHD in its current version, a GNU Radio that
uses that version and everything you need, from source:

http://pybombs.info

Then, try to ping your USRP:

ping <ip-address of your USRP>

If that doesn't work, you still have a network problem. Please refer to
[1] :)

Best regards,
Marcus
