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?
Thanks :)
