Yes, we've got a block that'll do that for you, gr.interleave. (We've also got the inverse, gr.deinterleave) src0 = ... src1 = ... interleave = gr.interleave(gr.sizeof_<items_in_src0_and_src1>) # E.g., gr.sizeof_float downstream = ... # your downstream block... fg.connect(src0, (interleave, 0)) fg.connect(src1, (interleave, 1)) fg.connect(interleave, downstream) Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
