Hi Songsong Gee,

when using gr_blocks, you can do all kinds of stuff like that. Remember
that you can output pretty much anything when receiving something. So
you could write a block that simply doesn't output anything as long as
no payload is being pushed into its input.

There are some examples for this. Check out
gnuradio-examples/python/digital.
