bladerf_sampling() error. Operation not supported

[MSmithDev]

I'm trying to get SDR# to work on the BladeRF 2.0 Micro A4. I've followed all the instructions. I get SDR# to see the device but when i try to start the device after a short pause this popup shows.

Here is the settings in SDR#

And my versions from bladerf-cli

It seems like something may have changed with the new 2.0 libbladerf

Thanks!

Thanks for reporting. I will try to have a look, hoping that it's not something specific to bladeRF2 because I don't have one to test.

Sure thing, I would be happy to test anything for you using mine. I think the issue is libbladerf 2.0 has some changes that may have affected your wrapper.

Ive got the same issue. Ive simply followed the instruction but it’s not workes. Then ive tryed to replace dlls in SDR # using libraries commes with nuand windows installation. Then its appiars the very same errors. If i can help something - ill be soon.

+1, this seems to be a common issue for BladeRF 2 devices. I also have the Micro A4 and am impacted in the same manner. bladerf-cli sees the radio just fine and can load the FPGA. Using the DLLs in this repo, the sources box is greyed out as if there is no device plugged in. By replacing the DLLs with Nuand's version, the device shows up without issue and the FPGA seems to flash just fine, however the same "Operation not supported" error is thrown. Occasionally, I'll receive a "source not ready" error on first try, followed by the operation not supported error on subsequent attempts to start.

libbladerf changed from version 2.0 onwards, LNA gain is no longer there, the code needs to be updated

Thanks for reporting and for identifying the bug.
At the moment I really don't have enough spare time to fix the API, update the GUI and (the most time consuming part) test that everything is working.

But I will do my best to update everything and support the latest additions before the end of summer.

@jmichelp Hi. Any updates on the progress for this bug? It is basically a blocker for using bladeRF on Windows...

[jmichelp]

Oops, I completely forgot about this issue.
I see that Nuand Labs has forked my repository and applied some fixes. Do they work? Because in that case, I can simply merge that into my repository and issue new pre-compiled binaries.

Any update to this? the new updates that was forked from Nuand Labs did not fix this issue.

Hello Guys,

Same issue experienced with Bladerf xA9, running on Windows 10. Symptoms exactly as described by uzc30 in issue #17 a year ago.

Is recommended way to wait until #16 is fixed here or better contact Nuand to fix in their fork?

Cheers
