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.

Regards,
Kyeong Su Shin

No, I installed it from the repos

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
