Re: [Discuss-gnuradio] FILE SINK Binary file error

Hi Ernest,

that question is asked pretty frequently, so here is a FAQ:

Best regards,

‎Hi Experts,

I attached the output of my file sink. 

I was expecting a chain of binaries. 

I want to plot this on matlab. 

File - Source can replay this signal though

But how I can I see the binary chain? Is this what is should be. All I see are strange letters.  

What is happening 

Thank you

Ernest.

I'm new to using gr-osmosdr and I'm trying to implement the equivalent set of USRP function calls for a HackRF

set_center_freq(target_freq)

get_sensor("lo_locked")

which amounts to measuring how long it takes to command a frequency change and lock at the new frequency.

The set_center_freq function happens to be the same, but I don't know where to find documentation or example code that shows the get_sensor equivalent, or if it's even needed. Would someone direct me to an API manual for gr-osmosdr, or source code that defines these things?

Thanks,

Rich
