limeConfig error -> cannot deliver requested frequency

Projects LimeSDR

Hi,
I’m using LimeXTRX and I wanted to test CLI Tools. I’m getting “lms7002m_set_frequency_cgen: cannot deliver requested frequency (1600000 Hz)” error even though I’m definitely setting appropriate value. For example :
$limeConfig -i --samplerate=200e3 --rxen=0 --txen=1 --txlo=100e6
I tested hardware with gnuradio using LimeSuiteNG blocks and it worked fine, limeDevice does return my Lime XTRX. I’m using Ubuntu22.04 and limesuiteng is installed from the source as described in guide.

200 kHz sample rate?

The default parameters for oversampling are different between limeConfig and GNURadio.
To achieve samplerate of 200e3 oversampling needs to be set to 32.
So with limeConfig add paramters for --rxoversample=32 --txoversample=32

Thanks, I had no idea that the problem was in samplerate not in lo, error showed up only after I passed on lo argument.
