Then: I see the USRP2 send mac pause frames, and then no new data is sent over the interface for 5-10 seconds. Since the USRP2 used pause frames even before UHD, it wouldn't surprise me if this is the same problem I encountered in UHD. Be sure to set the rx gain, frequency, etc and call start_rx_streaming BEFORE spinning up the tx thread. Try setting the system send buffer limit to something small. To set it temporarily: sudo sysctl -w net.core.wmem_max=10000 Then run your app. HTH. -Marc |
