Issue stream command is for RX, and this is exposed in python, so you can call it. Now for tx, if you wanted to transmit a fixed number of samples, its best that the producer of data frame the end of its bursts with a EOB tag. But I suppose something quick and dirty would be sig_source -> head -> usrp_sink A few examples here w/ the tags: http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNU_Radio_UHD#Using-UHD-Software-with-GNU-Radio -josh > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
