Reconfiguring the flowgraph after processing N samples

[Marcin Puchlik]

Hello Everyone,

I want to reconfigure my flowgraph after receiving N samples. I am following this example: https://www.gnuradio.org/doc/doxygen-3.7.4/index.html#reconfigure

Instead of using sleep(0.1) I want my flowgraph to lock after consumption of N samples. Then I want to rearrange the flowgraph blocks. Do you have any idea how to do this?

My guess is that I can use Performance Counters like nproduced for the first block in my flowgraph and base on that, call lock() function on my top_block(). What do you think?

Cheers

Marcin
