[Discuss-gnuradio] Packet based system

[Vamsi Krishna Adsumilli]

Hi,

Is there a way to existing block which sends out data only when packet arrives 
but keeps sending out nothing until then? I expected “PDU to tagged stream” 
block to work that way, but it seems like that block waits for input to fill to 
start sending out stream.

I would like to build something like a packet based system where packet occurs 
only at certain times.

Thanks in advance.
