Hi all, I would like to experiment with simple_ra but, after
installing it successfully, I got an error starting flowgraph as you
can see below; looking at simple_ra.grc all the ports are obviously
connected, so there is something else which at the moment I'm unable
to discover. It happens both with a B200 and with an RTL device. I'm
using ubuntu 14.04/ gnuradio 3.7.6
Any help is greatly accreciated, many thanks in advance,
Stefano
B200:
