Re: [Discuss-gnuradio] Controlling USRP From Inside General Gnuradio Block

[Firas Abbas]

Hi,

Yes I'm sure, when I remove (or mark //)  [d_center_freq = d_tune->calleval(0);] in enter_tune_delay () of bin_statistics.cc, the scanning speed increases rapidly. 

Is there away to solve this problem and control the USRP directly from the bin_statistics block?

Regards,
Firas
