Scheme upgrade to provide better experience: Master chip adopts ST crotex-M7 core, the main frequency is up to 400Mhz, fast processing speed, high stable and reliable performance.

Synchronized baud rate: Change the baud rate, data bit, check bit and stop bit dynamically via network protocol.

Network heartbeat packet: The serial device server sends a heartbeat packet regularly to notify the server that it is active and maintains a normal network connection with the server.

Serial heartbeat packet: The serial device server notifies the serial device it is active via packet, and this packet can also be used to actively capture sensor data.
