Hello Bin,
My group considered doing this about 4-5 months ago. Things may have changed now, but at that time it was not possible (or at least not straight forward to me) to get the gain from the AGC.
From my understanding, the AGC (automatic gain control) makes getting RSSI readings difficult because your signal is getting amplified before it gets sampled. So if you don't know the gain the AGC sets (which varies with time) it's hard to do RSSI.

Hello,
Anyone know if it is correct to roughly estimate RSSI information from I/Q values. For example is it correct to say RSSI of a message is equal to 10log10(I^2-Q^2). Otherwise, what is the correct way to obtain RSSI value in gnuradio?
Thanks,
Bin
