[Discuss-gnuradio] How to change modulation of examples/digital/ofdm/benchmark_rx.py dynamically

[Yubo Yan]

Hi all,

I am testing benchmark_rx.py in examples/digital/ofdm/ directory. I want change the modulation method dynamically when the flow graph is running. On way is that lock, disconnect, reconfigure, connect and then unlock flow graph. However, this way is often lead to program stuck. So is there any way else to change the modulation dynamically?

Regards,
