When transmitting, the GPIO value should be changed to 1, and to be sent successfully, the GPIO value should be changed to 0 immediately. Now, because the time point of transmitting successfully cannot be accurately found to change the GPIO value to 0 immediately, the modbus transmission success rate is low
