Re: [Discuss-gnuradio] extract value of signal

Hello Jafar,

If what you are asking for is a way to access data which are being generated (and outputted) by your pre-existing GNU Radio flowgraphs, the best way would be NOT extracting them. You can embed your own Python code to your GNU Radio flowgraph by writing Embedded Python Blocks (ex: http://aaronscher.com/GNU_Radio_Companion_Collection/Embedded_Python_Example1.html ,  http://aaronscher.com/GNU_Radio_Companion_Collection/Embedded_Python_Example2.html ,  http://aaronscher.com/GNU_Radio_Companion_Collection/Embedded_Python_Example3.html ,  http://aaronscher.com/GNU_Radio_Companion_Collection/Embedded_Python_Example4.html ).

If that does not work for you, you can use TCP, ZMQ or a file sink to extract your data. For non-real time processing, you will want to use a File Sink block to store your data into your disk. You can then parse the data by following descriptions in 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 .

Regards,

Kyeong Su Shin
