Sensitivity is not a context-free evaluation parameter--it depends
heavily on exactly what modulation is being used and other factors.
Which makes the concept of "sensitivity" in the standalone context
meaningless.
You haven't mentioned what daughtercard you're using in your N210,
so without that, we can't begin a discussion.

Hi Sumit - Do you have your GR OOT in a public repo where we could
review all of the code & try the example ourselves? That's the
most
reliable way to handle such potentially in-depth queries such as
yours.
As a quick reply without knowing more specifics, are you using the
"hier_block2" for the base class for your main block? If so, then
you
can't do signal processing within this block; all a "hier_block2"
block
is good for is encapsulating other blocks, connecting them
internally as
well as to the "hier_block2"s input(s) and output(s); no "work"
here!
>From the debug printout, likely candidates for this issue
would be the
block "fft_vxx" or "ieee802_11_soft_frame_equalizer_dc".
Hope this is useful! - MLD

Dave,
Thankyou. I partially resolved this by uninstalling UHD and GRC,
and using the latest PyBOMBS to compile from source both UHD and
GRC. The good news is that after installing the correct FPGA
image, GRC runs. Unfortunately it is not operating correctly.
GRC is throuwing codes Gt, the simple generate a cosine tone,
send it to the Ettus X310, then loop it back to the receiver for
display seems to only show LO leakage at 0 Hz. Additionally GRC
will not properly end, and I must force an exit.
Attached is the console output (text file). It looks like I have
some files from the old install that are interfering with the new
GRC install. I'm not sure where to look to erase them if so. Any
other idea's what is the issue?

I know gr-uhd just makes use of the system UHD install. Perhaps
you have two different locations that UHD is installed to? You
could double check that you don't have libuhd.so
in /usr/local/lib and /usr/lib at the same time. I'd suggest
updating the radios to the current firmware with uhd_image_loader,
power cycling them, and then trying again.

Hello Suresh,
Dump the SNR values in a file. Then read the file using
read_float_binary.m utility available in gr-utils/octave.
Hope this helps

Subject: [Discuss-gnuradio] ABI compatability mismatch
Message-ID:

Content-Type: text/plain; charset="utf-8"
I had newly installed gnuradio and its dependencies. I was careful
as I was aware of this error.
When uhd was installed , I had selected v3.12.0and the gnuradio
version was v13.4.0 (one of the latest but stable ones as of my
understanding)
When I connected B200 and run my programme, it showed this error.
RuntimeError:
GR-UHD detected ABI compatibility mismatch with UHD library.
GR-UHD was build against ABI: 3.12.0,
but UHD library reports ABI: 3.14.0
Suggestion: install an ABI compatible version of UHD,
or rebuild GR-UHD component against this ABI version.
How cold I possibly correct it?

Rebuild Gnu Radio against your installed UHD.
If you have a version of Gnu Radio installed from the package
manager,
make sure to remove it before installing the built-from-source
Gnu Radio.
