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:
source--->block B(just one block)--->sink
And I have read the API,and then I write something like this:
def main():
tb=my_top_block()
tb.start()
time.sleep(30)
#stop flowgraph
tb.lock()
tb.disconnect((tb.uhd_usrp_source_0,0),(tb.rx_0,0))
#start flowgraph
tb.connect((tb.uhd_usrp_source_0,0),(tb.rx_1,0))
tb.connect((tb.rx_1,0),tb.snk)
# blockA:(tb.rx_0,0) blockB:(tb.rx_1,0)
tb.unlock()
tb.wait()
But it go error: RuntimeError: delay(4): insufficient connected input ports
(1 needed, 0 connected)
Can someone help me?Thank you.
Best regards,
xd
