[Mini] ERROR: LML RX phase search FAIL

Hello,

I’m trying to test my LimeSDR mini according to: https://wiki.myriadrf.org/LimeSDR-USB_Quick_Test

When I get to “3.2 Load the configuration file” and try to load the self_test.ini, it produces the following output:

[18:44:58] INFO: Disconnected control port

I also tried to run this SoapySDR test: https://github.com/pothosware/SoapySDR/blob/master/python/apps/MeasureDelay.py

And it produces the following output:

$ python3 MeasureDelay.py --args=driver=“lime”

Any idea what could be wrong? Thanks!

This is for LimeSDR-USB, it will not work for LimeSDR-Mini.

Oh ok, thanks!

Are there any standard tests that I can run that would test the TX and RX functionality of my LimeSDR-Mini?

Hi @sccarey,

We have LimeQuickTest for this purpose.

That seems to work! Thanks!
