As was noted on this list earlier this week, the parameters are not currently changable in the GUI. If you're so inclined, please debug the problem and submit a patch. > I'm also still having the issue with not being able to connect to > connect to my network now that the USRP2 is set up. We recommend a dedicated GigE ethernet port on the host and a direct connect (no switch) between the USRP2 and the host. > If you have any suggestions or ideas what may be causing these > problems, please let me know. We use ethernet PAUSE frames to flow control the host. It's possible that if there's a switch in the path, that it's not dealing with them properly. It's not uncommon. Hence our recommendation for a direct connection. Note too that the USRP2 is capable of totally swamping medium peformance systems. 800Mb/s (decim=4) is probably way too much for many systems. Try decim=16. Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
