Re: [Discuss-gnuradio] how to trigger dynamic reconfiguration with lock/disconnect

[Yang]

Hi Johannes,

I think I have faced a similar problem like yours. I intend to implement a dynamic spectrum access system: sensing on the rx side and transmit on tx side. 

I solved the problem in a dumb way: I start and stop rx and tx block orderly in a while loop and use some global variables to store parameters that needs to be changed. It works well in most of time, but throw errors like "usrp2::samples() not receiving" in a few times.

I am interested in what you guys are discussing about, though something of it seems pretty abstract and vague to me.

Hi Scott,

This works well during testing. Once you get some kind of protocol or some
series of steps that you want to do, you can just test a flag, and whenever
your block finishes set it to true, then reconfigure.

What do you mean with "your block finishes" ? How do you implement this flags?

I am now using a thread to implement the state machine.
I am using member variables in the C++ blocks to implement the flags
or to hand over certain signals/values to the control thread.
