Good evening Sir, ..Sir i am working on GNURADIO tool..and i am
developing BPSK modulation and i tried SNR calculation in that and i
already calculated the SNR value and i want to send that
value in to text file,but i could not able to send that value in
to file.. please help me sir..please find outthe grc file
attached Thanks & Regards,Suresh T,Navstar Integrated Systems

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?

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 <http://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
Regards
Sumit

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.
