RE: Beginner Question: python script error when doing connect()

Eric,

I attempt to declare the source and the sink to both be the same type:

if options.input_shorts:
self._u = usrp2.sink_16sc(options.interface, options.mac_addr)
#the last True is to restart the file when it is done
self._src = gr.file_source(gr.sizeof_short,filename,True)
else:
self._u = usrp2.sink_32fc(options.interface, options.mac_addr)
#the last True is to restart the file when it is done
self._src = gr.file_source(gr.sizeof_gr_complex, filename, True)

…
self.connect(self._src, self._u);

Is this not correct?

Thanks,
Ilya

Use: 2*gr.sizeof_short

It’s complex, not short.

else:
self._u = usrp2.sink_32fc(options.interface, options.mac_addr)
#the last True is to restart the file when it is done
self._src = gr.file_source(gr.sizeof_gr_complex, filename, True)
