leaniiorx: unknown error

[jh4xsy]

Hi

I ran leaniiorx, then got following error.

% ./leaniiorx -f 2395e6 --bw 2000e3 -v
Setting RF bandwidth 2000 kHz
** IIO: in_voltage_sampling_frequency failed with Unknown error -2

I'm using PlutoSDR v0.27 with libiio 0.15 on openSUSE leap 15 x86-64 machine.

The "%" prompt suggests you running leaniiorx on the x86 host. This might work thanks to the IIO/USB abstraction, but I have never tested it.

Did you run another IIO application before leaniiorx ? Maybe the SDR is in a state that leaniiorx fails to handle properly.

Does running "dmesg" on the PlutoSDR reveal details about the error ?

Do you get the same error when running leaniiorx natively on the PlutoSDR ?

YES, I ran leaniiorx on the x86 host + PlutoSDR as USB peripheral. I think I can handle PlutoSDR via libiio. Before leaniiorx, I tried GNU Radio + gr-iio. it works.

I dig dmesg and journald logs, but there is NO information about the error.

So I tried PlutoSDR native leaniiorx which you provided at http://www.pabr.org/radio/leantrx/leantrx-20180211.zip. I ran this on my PlutoSDR with NO error! Perfect!

PlutoSDR have about 230MB room to save IQ files. Maybe execute leaniiorx on the PlutoSDR is enough for my usage.

Note that you will need to specify --nbufs to take advantage of the 230 MB and also to work around a bug (missing default value).

Keeping this issue open until I test over IIO/USB.
