Re: [Discuss-gnuradio] Single step a stream

Yes you can debug any gnuradio c++ module with gdb.

Step 1 uninstall gnuradio. 

Step 2 git clone gnuradio from github. 

Step 3 build gnuradio with debug symbols on. ( cmake .. -DCMAKE_BUILD_TYPE=Debug ) 

Step 4 reinstall custom build gnuradio.

Step 5 debug your application with gdb ( use qtcreator, vscode, atom as ide will be good  )

With gdb you can stop anywhere in application. Set a data breakpoint can trace stray value in variable.

Hi,

 

Is it possible to single step a flow graph?

 

I have a recorded stream of FSK modulated data with about 25 bursts of messages.
When this is later decoded I do not get 100% detection, about 4 of 25 bursts fails.

 

Now my thinking is can I play this burst by burst and see what is wrong.
So my plan was to stop the scheduler after each burst.
Can I control (stop) the scheduler when a 'tag' is detected and restart it with a GUI button.

 

Block,Python,C++ dosen't matter...
