We have our QAM waveform running successfully using Matlab/Simulink and the X310 USRP. We run with two laptops and two X310 USRPs and we can continuously sends Pings between the two laptops. We get no underruns and everything works fine as long as the data stream is continuous to the USRP (SDRu Transmitter block). Now we want to use the USRPs in burst mode where we only want the USRP to transmit when data is present. We have tried several combinations of setting the Enable Burst Mode checkbox in both the SDRu Transmitter and SDRu Receiver block. We have also tried putting an Enable on the SDRu Transmitter block. We have tried sending from 1-8 frames periodically to the SDRu Transmitter block. We put a scope on the receive side and never see a corresponding reception that shows only the frames we thought we sent. Question: How do we get the SDRu Transmitter to transmit only when frames are sent to it?
