Hi
I am trying to run the dial_tone_source.py in the examples folder
“network”
with its default arguments but I get the following error:
“udp_sink: Connection refused”
Can anyone tell me why I am getting this error?
and when I run dial_tone_sink.py, I get this message:
“gr_block_executor: source <gr_block udp_source (1)> returned 0 from
work.
We’re marking it DONE.”
what does it mean?
