so if you replace lines 70-79 and replace them with tb.stop(), you get
bytes in your file? How many? Is it much more than 52*8? Do you actually
guarantee that there should be output of ofdm_rx_0 or does this happen
coincidentially?
Something as complex as an OFDM receiver really shouldn't be used
Hi Marcus:
Thank you so much for your kindly reply.I have attached my
code.I want to run the flowgraph 1 at first,and then I disconnct it.Then I want

Flowgraph 1:
uhd_usrp_source>>>ofdm_rx_0>>>file sink

Hi Marcus:
Thank you for your reply.Sorry for that if you can't
understand.I will try my best to explain my question.
def main():
tb=my_top_block()
tb.start()
time.sleep(30)
#stop flowgraph
tb.lock()
Xianda,
my advice: Please try to draw a complete picture of what you are doing.
What are your sources, blocks you interchange, your sinks, what do you
do to make your flowgraph stop (under which circumstances)? I really
can't read your mind; all I know about your flow graph is what you tell
me, whi
Hi xianda,
tb.wait() does exactly what you said it does: Wait for the flow graph to
complete.A flowgraph will run until one of the blocks in that flowgraph
signal that they're done, or you call tb.stop().
If you don't have such a block, your tb will run forever, and wait()
will never return.

Hi Xianda,
as usual, saying "doesn't work", "can't run", "behaves wrong" really
gives no clue what's wrong.
Please follow

especially "How do I ask?".

unless you also disconnect block A and sink1, GNU Radio will continue to
assume that block A should produce output for sink1, and it can't do
that without input.

I forget to say:the "sink" also different with each other.Namely:
source--->block A(just one block)--->sink1
source--->block B(just one block)--->sink2
Can someone help me?Thanks.

Hi all:
Thank you in advance.I want to ask some questions about the
"Reconfiguring Flowgraphs".
My flowgraphs:
source--->block A(just one block)--->sink
And I want to run the flowgraphs for 30 seconds,and then run the other
flowgraphs:
