Re: Modifying File Sink

Thanks for the response Marcus appreciate it!

But can you explain more how can I use "constructed" filename that includes frequency information? I have QT GUI Range which has ID lo_freq, when I tried to insert that info into file sink's file section like "C:\Users\aydindi\Desktop\sept_2\buff1_lo_freq.txt", extracted file does not contain numerical freq info as expected..

I can handle multiple separated txt files in matlab using a for loop. I would like to modify file sink like (' buff1_%d.txt ', lo_freq) but I am not quite sure about the file section accepts this kind of input.

for i=1:6

    f = fopen(sprintf('pll_re_1_3_%d.txt', i), 'rb');

    rx_pll_re{i} = fread(f, Inf, 'float');

    fclose all;

    f = fopen(sprintf('pll_im_1_3_%d.txt', i), 'rb');

    rx_pll_im{i} = fread(f, Inf, 'float');

    fclose all;

end

Dear all,

I would like to modify the file sink so that when I changed the receiver frequency during simulation, the file sink will create a new file and record new frequency data there. Is it possible to do that? and where can I find the source code of the existing file sink in gnu radio?

Regards,

You don't need to modify the filesink to do that. You just have to use a "constructed" filename that includes frequency information.
When the filename changes, the filesink will automatically close the current file and start a new one under the new name.

Gnu Radio source is on github:

https://github.com/gnuradio/gnuradio

gr-blocks/lib is where filesink_impl and filesink_base live.
