LimeSDR Mini - can I specify antenna through soapy options?

I’m trying to use the LimeSDR Mini with rx_tools, which is a command line FM decoder. I’ve noticed that on this tool, when it starts to run it will start a calibration and then after a few seconds

[ERROR] Rx calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?)

will appear followed by a few higher level messages about the readStream read failing and then dongle_thread_fn terminating. I get no output.

I’d like to make sure that the correct antenna is selected, but I can’t figure out how to do this through the soapy options. “driver=lime,index=0” is fine, and while SoapySDRUtil --probe=“driver=lime” shows me all of the information, the one bit it doesn’t show is what the soapy option to select the antenna is.

Similarly, when soapy probes the device it gets a list of two sample rates (100k and 65m) which I understand is a range, but then it also states there are 0 bandwidths. How can I specify the bandwidth of the filter?


I would also like to know this information.

Any updates on this?
