in another terminal for benchmark_rx i am passing this benchmark_rx.py -a serial=4d05ac4b -f 2.2G -m gmsk -r 240 --rx-gain=20
forrx and alsofor uhd_fft it is printing the same oooooooo continues.
Thank you.
I wouldn’t call the benchmark examples the “very basic.” You still need
to
understand and calibrate a lot of your system before you can get it to
work. If you’re new, you should start with our tutorials:
Tom is absolutely right. Benchmark_tx is something that illustrates
some very interesting aspects of GNU Radio, but it’s not something you
start with, because the things you see won’t mean a thing to you. So
do the guided tutorials, and if you feel like you’re missing out on
some theoretical aspects, maybe pay the “suggested reading” page a
visit.
Overflows mean that your PC is too slow to keep up with the real
time sample processing. Basically, this is nothing that you can solve
by doing anything within the “basic” usage of GNU Radio. It just means
your machine is too slow.
Further, I’m not sure that benchmark_tx/rx can actually do bit rates as
low as 240 bits/second, because the have a fairly-simple symbol-rate
model, and the USRP1 can only support sample rates down to 192k.
You said that uhd_fft also produced ‘O’ indications–what parameters
were you using with uhd_fft?
