Benchmark_rx.py

Hello all,
i’m trying to send and receive data using benchmark_tx.py and
benchmark_rx.py

When i run benchmark_rx.py the rx_callback is not being executed. None
og
the print statements in the rx_callback is getting being printed.

I get the warning failed to enable realtime scheduling.

I’m already running both tx and rx in verbose(-v) .

That warning isn’t critical, and you should be able to receive packets
anyway.

Run again with --log, and look at the outputted .dat files (either in
octave with the instructions on the gnuradio website or using the
provided gr_plot_const.py and friends) to see if they look remotely
close to what you expect. (compare and contrast with the output of
benchmark_loopback.py --log).
If nothing is being printed that’s usually (for me, at least) a sign
that the link between the two radios isn’t good enough for anything to
make it through.

What are the full command lines you’re using for each (tx and rx)?

Hi there,

I’ve used the file gr_plot_const.py to plot the output data from using
benchmark_rx.py with the --log command.
However there are 8 files (rx_unpack, rx_symbol_mapper,
rx_slicer,rx_rrc_filter, rx_prescaler, rx_prescaler, rx_receiver,
rx_diffdec
) which one is the final received data I don’t , can any body tells me ?
(I’m using the benchmark_tx.py with dbpsk as modulation) .

regards,
