Controlling the digital output of UC3X with a MQTT command, I have noticed that the MQTT command payload does not have sequence. How do you ensure that the reply is for a specific command?
There is no mention of the QoS for your MQTT communication. Which one is used?

Use power adapter to supply power to UC3452. If it's only powered by USB, the device system can not work steadily.
Please change another USB cable or another PC.
