[Discuss-gnuradio] [discuss-gnuradio] The Gnu radio's stream mode

[Pan, Luyuan]

Hello everybody,
    Many people say the Gnuradio operates in stream mode with the flowgraph, 
but I am not clear about the stream mode, for it is too abstract. Does anyone 
have a better way to understand it or interpret it in plain words? And one 
thesis says,'Gnu Radio is not designed to work in packet mode, rather the 
scheduler is designed to operate on continuous data stream', so if I want to 
get precise-time control of the data packet, what should I do? (What I recently 
do is to switch the TX/RX using one antenna, I just make two top_blocks and 
switch them, the problem is there is too much delay. If I want to send 5 
seconds, I also need to wait to 1.5 sec to make sure it successfully sent all 
the data)
    Can I so lucky to reference someone's information or get a hand from you?
    Thanks very much !
