hello all:
I am a newer to the Gnuradio. And recently I use USRP
and GRC to make some examples. But I have a problem about the scope_sink
in the GRC.
there are some block which I used in my graph:
signal_source->packet_encoder->Gmsk_mod->USRP_sink
USRP_source->Gmsk_demod->packet_decoder->scope_sink
When I run the graph, I can not see anythin in the
scope_sink, which mean I can not see the demodulated waveform, can
anyone tell me why this had happende? By the way,the USRP which I used
is RFX2400 and works well.
Thank
you very much and I apperciate the answer.
