Hi Devin,
the padding with zeros unless samples occur within a specific time job
can be done with gr-eventstream [1] [2] , but:
If you're going to use USRP sink anyway, what about using tagged stream
blocks[3]?
You could replace your Pull Source with a Pull Message Source -
PDU to tagged
I have a flowgraph that I'm trying to develop in simulation first before
deploying to some sort of hardware like a USRP. The flowgraph begins with
a ZMQ Pull Source and then I have all my signal processing blocks
afterwards (eventually there would be a UHD Sink). The ZMQ block only
produces
