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

As you said first,it was a network problem but I fixed now.

Now when write in the command uhd_usrp_probe --args "addr=192.168.10.1" it will show

sudo uhd_usrp_probe --args "addr=192.168.10.1"

linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.010.git-89-gb17b440d

But if write uhd_usrp_probe it will not detect the device

Error: LookupError: KeyError: No devices found for ----->

Empty Device Address

- Below is my UHD block parameters Is it correct ?

Also Is there any images should I install for USRP-2921 ?

Thank you very much

Hi Mohamed,

You're really not annoying; it's really nice to have you here!
I'm taking the usrp-users list into CC: here, and would like you to sign up [1]for that and follow up there; this discussion doesn't have much to do with GNU Radio, yet :)

I generally do not recommend using virtualization for high rate, real time signal processing like you want to do, unless you know very well how to set up your virtualizer in a manner that supports low-latency, high-rate network communication.
Generally, this is with almost 99% probability a network problem, made more complicated by the fact that you're in a VM.
What you really should not do is use NAT to connect your VM to your host computer's network card; make sure you use a bridged network configuration instead.

Best regards,
Marcus

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
