Question: using gr_float_to_complex

Hi everyone!

I have this problem with using gr_float_to_complex. I wanted to connect
two
sptr types wherein one contains floats while the other is an sptr type
of
gr_float_to_complex. Unfortunately, I always get an error message saying
‘port number out of range.’ What should I do?

Sample Code:

Rx1 (<class
‘gnuradio.gr.gnuradio_swig_py_gengen.gr_vector_sink_f_sptr’>) #
contains the float data
Rx1_comp = gr.float_to_complex()
fg_Rx1_comp = gr.flow_graph()
fg_Rx1_comp.connect(Rx1,Rx1_comp) # I get error messages here
saying
that ‘port number out of range’

Thanks!

:slight_smile:

Should Rx1 be a vector_source_f rather than a vector_sink_f?
