Re: [Discuss-gnuradio] UHD USRP sink does not react to gain changes (gr-ieee802-11: between two usrp devices)

[Nasi]

Just to be sure: do you have the current version? (some weeks ago I normalized the signal power to 1 without pushing updates of the flow graphs. That lead to distorted signals. In that case, changing the gain does not help.)

I reinstalled it previous week, I guess on Saturday. Before it was not working at all. I think this can cause a problem... Where do you normalize that?

Thanks, I guess the problem is that just very few samples of your incoming stream belong to WiFi frames. So chances are that the frame is not visualised at all (I think that the FTT sink uses a subset of the samples based on the sample rate and the update rate of the GUI). If you really want to stick to this approach I would recommend to checkout gr-fosphor. I found it really helpful.

No, I changed the transmission frequency to smt. different 5.94. If I don't run tx, rx receives nothing. When I start tx rx starts to receive smt. 
Another thing I think the frame is visualized since when I increase rx gain in receiver side the curve goes higher.
