[Discuss-gnuradio] Issue trying to run simple_ra

[Jose Ruvalcaba]

Hello,

I installed and tried to run the simple_ra_receiver flowgraph using a USRP N210 and was shown the following error message:

aster$ simple_ra

I updated osmosdr to the latest version from https://github.com/osmocom/gr-osmosdr

but I still get the same issue.

Any ideas?

Thanks,

Jose
