Re: BladeRF 2.0 xA4 error "Failed to open BladeRF device in GNU Radio

I first installed the bladeRF from the ubuntu repo, but it didn't work (bladeRF-cli did not recognize the board), then I added the ppa from

https://github.com/Nuand/bladeRF/wiki/Getting-Started%3A-Linux#Easy_installation_for_Ubuntu_The_bladeRF_PPA

I did what is said there and the the blade is recognized but it does not work from GRC.

I will see if there is a version of gr-osmosdr in thet repo.

Hello Fernando:

Did you install libbladerf from the main Ubuntu repo? Or, from some other repo?

I am no expert of BladeRF, but I think the version of libbladerf shipped with Ubuntu 18.04 (which is from 2016) is a bit too old for BladeRF 2.0. If you really installed that and if that correctly recognized your BladeRF, then I am not sure what is causing the problem. Manually building gr-osmosdr is still worth a shot.

If you installed it from some other sources (maybe from some PPA or repos that are not maintained by Canonical), then you definitely need to use a custom version of gr-osmosdr (maybe provided by them), or build that by yourself. Make sure to uninstall the currently installed version of gr-osmosdr before proceeding. Also, it may have accidentally installed a different version of libbladerf to your system, so you have to check that, too.

No, I installed it from the repos

How did you install libbladerf and gr-osmosdr? Did you try manually building gr-osmosdr?

제목: BladeRF 2.0 xA4 error "Failed to open BladeRF device in GNU Radio

I have just received my bladeRF 2.0.

I have configured udev rules and upgrade bladeRF in ubuntu 18.04. It seems the blade is working well, but I get this error when using it with GRC

This is the diagram I'm using

I have been testing the blade with bladeRF-cli and all seems to work well

and it is getting the samples at the csv file.

Any idea what may be the problem with GCR?

best regards
