Hello Harold: Make sure that UHD can see the USRP. Try running "uhd_usrp_probe" with no command-line arguments.
Do you have a firewall running on your system? You can check with "sudo iptables -L". If you are running one, then try shutting it down, and re-running your flowgraph. You can safely shut down your firewall with the following commands: sudo iptables -P INPUT ACCEPT sudo iptables -P OUTPUT ACCEPT sudo iptables -F --Neel On Thu, Aug 28, 2014 at 6:26 PM, haroldmk <harol...@gmail.com> wrote: > Hello everyone, > > I am using USRP for the first time.
