[Discuss-gnuradio] Switching from the receiving mode to the transmitting mode?
Dear All, I am working on an application where I have a sender S and a receiver R. The procesure runs as follows: (1) S transmits the channel estimation sequence. R estimates channel. (2) S switches to receiving mode. R switches to the transmiting mode. R sends the channel estimation back to S. (3) S switches back to transmiting mode. R switches back to the receiving mode. S sends data to R. For both S and R, I created two flow graphs, one for transmiting and the other for receiving. When switching modes, I was basically starting and stopping flow graphs. I found that I have to stay in step (1) and (2) for at least 0.1 sec. Are you aware of any faster method to do this? Thanks so much for any hint!

Best regards, Zhenghao Use Auto Transmit/Receive switching (ATR) and see tunnel.py for an example that uses it. (It's a terrible example of a MAC, but does show how to set up something similar to what you want.) No need to stop the flow graphs.
