Don't erase stuff because it takes time...
tb.wait() is necessary to let the top block wait for all the work to
finish.
GNU Radio flowgraphs will run until a) a block signals that it's done,
or b) the flow graph is stopped.
I think you want to use the "a)" approach. Add a Head block into your
flowgraph:
http://gnuradio.org/doc/doxygen/classgr_1_1blocks_1_1head.html
Your flow graph will then terminate after a specified number of
samples has passed the head block.
So what your program does is
tb.start()
tb.wait()
outpput=sink.data()

[Discuss-gnuradio] Check The output of a block & input captured frames to GNURadio
I want to make a test and see the output , I put 3 blocks , vector source , throttle and vector sink . I edited the "vector" parameter in vector source block to (6,6). All 3 blocks have a type "byte". I generated the flow graph. I moved to the directory of grc file , I wrote in terminal vim top_block.py then I write to the end of file : " print tb.blocks_vector_sink_x_0.data()" and saved the changes . Then I execute the python file by writing in terminal : ./top_block.py But the output takes too long time and doesn't appear ! what is the problem ? and is there any other method to see the output ???As I am a beginner and someone told me this method. I tried this for example 10 times but every time it takes too long and doesn't appear , only one time it appears! Another question : If I have captured some frames using wireshark (from twinkle softphone), and I saved them .I want to make them an input to ofdm transmitter . How to make them an input?
