the TCP Server. Abnormal network disconnection will cause the module to reconnect actively.
2.6.3. Module as UDP Server

UDP Server
In this mode, the module opens the local designated port. Once the data sent to this port is
received, the module will send the data to the serial port and record the remote ip and port. The
module will only record the remote information of the last connection, and the data sent by the serial
port will be sent directly to the recorded remote ip and port.
2.6.4. Module as UDP Client
