[Hackrf-dev] GNU Radio Audio from UDP

[Mitja kocjančič]

Hi I have some program that sends Audio via UDP to some other computer
(here it is: http://downloads.dxing.si/gnu/WavUDP/Release.zip )

now I would like to feed this into GNU Radio and for this I am using this
flowgraph: http://downloads.dxing.si/gnu/WavUDP/udp_rx.grc

But I always get some strange error:

>>> Done

Generating: "I:\Users\Mitja\SDR\HackRF\WINDOWS TX\GNURadio\test
grc\udp_rx.py"

Executing: "I:\Users\Mitja\SDR\HackRF\WINDOWS TX\GNURadio\test
grc\udp_rx.py"

Traceback (most recent call last):

  File "I:\Users\Mitja\SDR\HackRF\WINDOWS TX\GNURadio\test grc\udp_rx.py",
line 81, in <module>

    tb = udp_rx()

  File "I:\Users\Mitja\SDR\HackRF\WINDOWS TX\GNURadio\test grc\udp_rx.py",
line 60, in __init__

    self.blocks_udp_source_0 = blocks.udp_source(gr.sizeof_short*1,
"127.0.0.1", 7355, 1472, True)

  File "C:\Program Files
(x86)\gnuradio\lib\site-packages\gnuradio\blocks\blocks_swig5.py", line
963, in make

    return _blocks_swig5.udp_source_make(itemsize, host, port,
payload_size, eof)

RuntimeError
>>> Done

So I don't know what to do now?

Thanks for Anwsering and Best Regards
