Hi Ali - I think the issue is that the output of the C2M is of item_size 'fftsize', whereas the message_sink has item_size of 'gr.sizeof_float'. Try incorporating the 'gr.vector_to_stream' you created between the C2M and the message_sink. - MLD On May 21, 2009, at 11:34 AM, ali siddiqi wro

Hi, I am trying to make a flowgraph as given: 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
