I’m working on a flow graph that reads samples from a file and feeds
them to the wfm demod block. I managed to get this working, but along
the way I ran across a problem …
My data file is 16bit complex shorts in big-endian format. It looks
like the file source block reads data from the file and sends it to
the fm demod which is expecting a complex float data. I attempted a
quick test by using the original data file (wrong format) which caused
the flow graph to crash with a seg fault. After converting the data to
a complex float representation the flowgraph works.
Do people view this as a problem? It seems like the file source block
should attempt some form of sanity checking on incoming data. If you
aren’t expecting a problem, I could see this being hard for people new
to GNU Radio to debug.
