I am using qt C++ to refactor the dfu master station, currently I have a problem, that is, I want to communicate with 52840 simulated com but failed, I initialize, you see this is correct, I try to initialize the send command 0x06,0x01,0x0c after successful sending DFU did not respond, I want to know what's wrong. Thank you
