Re: [Discuss-gnuradio] File sink Reading issue

[Marcus Müller]

Dear Jahnavendra,

first of all: please avoid cross-posting if not really necessary. this is a GNU Radio, not a USRP-users problem.

Also, I'm absolutely not sure what I *personally* have to do with that, and thus, why I'm in there in the personal To: lines (or why Juha and Lars and Nate are) but oh well, since I also am on both mailing list:

 file contains i think ascii characters

No, it doesn't. Not at all!

I've already linked to the relevant FAQ entry, I'll happily do that again:

https://wiki.gnuradio.org/index.php/FAQ#What_is_the_file_format_of_a_file_sink.3F_How_can_I_read_files_produced_by_a_file_sink.3F

So, this is simply plain raw binary data, and not ASCII at all. The FAQ entry has source code that shows how to read these things, e.g. from Matlab/octave and python. In C and C++, and many other languages, reading raw data is just as easy; in fact, the functions are often even called the same (fread).

Best regards,
Marcus
