AT+MODE=1,2,3

2. *Set the local port number

AT+SVRPORTIP=4001

3. *Set the UDP communication list. This step is to distinguish the source of UDP data, and 4 groups can be set.

AT+SOCKET=0,4001,192.168.1.2

AT+SOCKET=1,4002,192.168.1.2

AT+SOCKET=2,4003,192.168.1.2

AT+SOCKET=3,4004,192.168.1.2

This is just for demonstration, and the actual value can be set by itself as needed.
