Communication is to use non-blocking type, namely a send send command reads the command, and then through component receives a trigger to start the data read, so if I want to implement blocking type of communication, how to write, efficiency is the best?
Do after the send a global symbol, the main thread loop to see this logo (here is the card), receiving a trigger clear sign

Please people, see any good solution, thank you
