I am trying to sense atransmitted signal using a usrp. I typed the
following command (/usrp_spectrum_sense.py 440M 450M --fft 512) and
worked a couple of times. But when I try it today, it tells me that
there is no device. (even though I connected a usrp). part of the
message I get looks like this.
RuntimeError: LookupError: KeyError: No devices found for ----->
Empty Device Address
I need help please.
