Hello GR list,
I am intending to read RSSI values on a RX (USRP N210),
I have found in the post of Marcus D. Leech in
https://www.ruby-forum.com/topic/1857766
10*LOG10(DECIMATE(SINGLE_POLE_IIR_FILTER(COMPLEX_TO_MAG**2(SIGNAL))))
Using GRC, I tried to implement that method of calculation as shown in the
attached figure,
1/ Is the flowgraph correct, or is there any missing block (decimation) ?
There are blocks in GRC to do all of that.
2/ Then how can I read in human readable format (ASCII) the RSSI values from
the test_RSSI.txt file sink ?
3/ Is there a way to co
Use a "head" block -- you can tell it how many samples to process
mmand the duration of execution of the flowgraph
within GRC () ?
4/ How can I format the test_RSSI.txt file sink to obtain single RSSI values
per line ?
The file-sink blocks write out data values in raw-binary format, not
ASCII text.
You could use a "probe" and poll the probe at 1Hz and have it call a
Python function of your own to to the ASCII conversions.
Any explanations are welcome,
Regards,
Naceur
