[Discuss-gnuradio] Packet Flowgraph and underflows

[Wolfgang Nagele]

Hi,

I've been looking for a solution to this and can't seem to find any examples.

If I have a flowgraph that transmits packets for instance from a TCP
stream - if this TCP stream only receives data occasionally it will
create underflows (showing up as U characters on STDOUT).

What is the proper way of handling such a scenario? I thought of using
something like the Mute block to transmit a 0 data stream during
periods of no data. However that seems excessively complicated to
implement and I think I am missing some pointer here ...

Thanks,
Wolfgang
