[Discuss-gnuradio] Howto tune RF frequency in blocks?

[2 1]

Hi,

 

I wonder if it is possible to tune the RF frequency in blocks written in c++.

 

In python, statements as the follow are used to tune the frequency of RF board.

r = u.tune(0, subdev, freq)

 

I want to adjust the receiver's RF according that of the transmitter  automatically with some frequency offset estimation methods before doing communication. I guess it's better to do the adjustment in DSP blocks.

 

Thanks!
