I am now using USRP2. I met a problem of setting a gain. When I call the function u.set_gain(option.gain), it seems it does not work. The gain range shows up to be [0.0 0.0 0.0]. The code works with USRP1. My gnuradio version is 11422. I can set gain using command usrp2_fft.py -g 80 but not with my own code. Thank you for your help.
Sincerely
