In the transparent transmission mode, it can be completely compatible with the user's original
software platform. User equipment can basically support wireless data transmission without making
software changes, as shown in the following

6.1.2 SERIAL COMMAND MODE
In this mode, users can send data to servers according to our protocol, and can send data to
different servers without restarting.
In this mode, when the RS232/485 TO WIFI ETH (B) serial server is used as UDPClient or TCPClient,
users are allowed to send serial data to different servers, regardless of the number of Soc0ket.
The client's MCU only needs to send data packets according to the format specified by our
company, and the serial server will parse the received data. If the data conforms to the protocol, the
serial server will send the parsed data to the designated server. If the data does not conform to the
protocol, it will be treated as a waste package without sending it to the server.
The client MCU sends the data packet according to the following format, and after the WIFI serial
server finishes parsing, only N bytes of data are sent to the target address. When data is returned, the
data is directly output from the serial port without parsing.
