Set block parameters / variables from cmd line?

GNU Radio
1

Hi,

i want to run an gnuradio .py application from the command line and want
to choose parameters (like the frequency or sound level) on the command
line. So i think about if it is possible to set block parameters /
variables without graphical sliders or graphical textboxes from the
command line.

Like:

python application.py -f frequency -s sound_level

cheers,
Andy

You want a “Parameter” block, from the Variables section.

GDB has a ‘break’ feature; why doesn’t it have ‘fix’ too?

If i use the parameter block with the default “ID=parameter_0” and with
“Type=Int” and type on the cmd line:

python application.py --parameter_0 10

i get the error message:

application.py: error: no such option: --parameter_0

Do i understand something wrong about the parameter block ?

here’s an example. “python parameter_demo.py --help”

maybe run your script with --help to see what options it will accept…
