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
?) ?
2/ Then, how can I read in human readable format (ASCII) the RSSI values
(expected to be in dBm) from the test_RSSI.txt file sink ?
3/ Is there a way to command the duration of execution of a flowgraph
within
GRC () ?
4/ How can I format the test_RSSI.txt file sink to obtain single RSSI
values
per line ?

Any explanations are welcome,

Naceur
