select daughterboard on usrp via soapysdr

[PripyatAutomations]

in most soapysdr applications, you can pass a device string to it. Is there a way to pass the subdev=B0 to my usrp x300? Be nice to access HF in sdr++. Great program, thanks!

Hi,

The SoapySDR source doesn't allow for these types of settings and support is not planned. However:

I've been working with Ettus Research to support all USRPs natively. Due to issues on some distros, the module is not currently included in prebuilt versions, but you can build SDR++ from source and enable the usrp_source module (add -DOPT_BUILD_USRP_SOURCE=ON to the cmake arguments). It's currently fully tested and working with the x300 series (I test with an x310 here). All combinations of daughterboards are supported.

[PripyatAutomations]

Thanks so much! I'll try it tonight.

Got that done, but as soon as selecting the new source i get a crash - Let me know if i can do anything to aid in debugging. Appreciate your help Alexandre!

can you run uhd_usrp_probe and send back everything it prints?

[AlexandreRouma]

This is strange. I assume something goofy is being passed to SDR++ causing it to try to create multiple entries for either the samplerate or bandwidth. Without having a LFRX board here it's hard to say because I'd need to see exactly what the API returns. If you know your way around C/C++ you could add a line or two in the selectChannel() function of the source_modules/usrp_source/src/main.cpp file to print out the ranges for samplerate and banwidth returned by libUHD (lines 138 and 159).

[PripyatAutomations]

Thanks again for taking a look at this.
threw in some fprintf's
// Get bandwidth ranges
bandwidths.clear();
fprintf(stderr, "bwclear\n");
bandwidths.define(0, "Auto", 0);
fprintf(stderr, "bw define auto\n");
uhd::meta_range_t bwRange = dev->get_rx_bandwidth_range(chanId);
fprintf(stderr, "get bw range\n");

    for (const auto& r : bwRange) {
        fprintf(stderr, "loop: %d\n", r);
        double step = (r.step() == 0.0) ? 100e3 : r.step();
        for (double i = r.start(); i <= r.stop(); i += step) {
            bandwidths.define((int)i, getBandwdithScaled(i), i);
            fprintf(stderr, "bwidth: %f\n", i);
        }
    }

[PripyatAutomations]

moving the fprintf in the inner loop up to before the faulting line, bandwidths.define((int)i, getBandwdithScaled(i), i);, i get bwidth: 0.000000

[AlexandreRouma]

It seems to be a bug with UHD, returning a 0 bandwidth makes no sense at all. I'll add a work around

[AlexandreRouma]

Actually, I'd need to know a bit more, could you replace fprintf(stderr, "bwidth: %f\n", i); with fprintf(stderr, "bwidth: %lf -> %lf\n", r.start(), r.stop());. Should print the exact range.

[PripyatAutomations]

I threw an if (> 0) in there. Seems work. Thanks! Saved me many hours

[AlexandreRouma]

Well it's a work around in your case but I'd like to fix it properly so that it doesn't happen on other hardware.

[PripyatAutomations]

Absolutely. I've wandered outside for some fire with friends but I'll make the requested changes and post output in a few hours. Thanks for the assistance. Saved me a lot of time getting it going!

[PripyatAutomations]

A little more poking at it and interestingly after removing the if (>0) it still works until i change devices in the devices drop down to any of the strange soundcard devices. then we crash..

Problem seems to have come from the first of those happens to be the default until get in far enough to select the actual USRP device. by adding that if (...) continue in there

this is what i get in the drop down. -- Any of the soapy ... options will crash sdr++.

[AlexandreRouma]

I'm not sure what those soapy devices are because I don't have them on either linux or windows but they return junk data.

[PripyatAutomations]

They're sound card devices in pulse audio. They show up in gqrx, etc too, it just seems to avoid them.
