Dear Community Team,
I started my flowgraph with getting real /imaginary data from a signal source using File Sink block as shown in figure below. Generate Options is NO GUI - Run to Completion.
Then I develop a python script to sweep amplitude and display their imaginary value over certain of frequency range like picture below.
Now I'm very excited to add FMCOMMS2 sink/source blocks and perform similar python scripts like my initial program above.
Basically, there is no parameter is passing to both self.iio_fmcomms2_source_0 or self.iio_fmcomms2_sink_0, in order me to maintain the similarity of python program. All parameters on fmcomms2 bloks are predefine as shown in top_block figure below.
However I got message Error Unable to create buffer :-16. This is puzzle to me since by adding this fmcomms2 blocks should not effect any my python code flow anyway.
Pls give some idea how to solve this issue. Thank you.
