Hello,
I've constructed the Spectrum Analyzer as seen on this page (see
following link to GNU radio wiki) in hopes to test the
functionality of GNU radio's compatibility with the b200-mini I
plan to use for a project:
Unfortunately,
when I run execute the flow graph, I get:
RuntimeError:
LookupError: KeyError: No devices found for -----> Empty
Device Address
and
it doesn't run as intended. I've verified the connection of
the device through UHD command uhd_find_devices (as well as
several other commands), where it sees the b200-mini just
fine, but GNU Radio isn't seeing it for some reason. The
device is interfaced via USB.
This
is similar to the error this StackExchange user encountered
(see link below), but I was slightly confused on how to fix it
with the advice provided in the highest-upvoted response.
If
it has any effect on anything, I downloaded GNU Radio using
the three lines at the top of the UbuntuInstall page on the
wiki (linked below):
I
am new to GNU Radio as well as the operation of the b200-mini
and SDRs in general. Help would be greatly appreciated!
Thanks,
Alex
