signal source --> stream2vector --> fft --> c2m --> msg_sink
If the size of fft is 4096, then I want to retrieve these 4096 points in python and then do simple maths and logic based on some of the values within these 4096 points within python.
And then based on the result, I want to initiate another flowgraph!
Currently, there is an error between the interface between c2m and msg_sink.
The code is:
class top(gr.top_block): def __init__(self):
gr.top_block.__init__(self)
