UDP server refers to the normal UDP are not validated on the basis of the source IP address, destination
IP instead of the UDP packets are received data source IP, similar to TCP server functionality.
In this mode, the module by default record a destination IP, when a serial port data, to record the IP to
send data, at the same time, the module at the server status, to accept the network packets sent to module,
and adjust the target IP IP for the data source, suitable for multiple IP working mode for the module.
Use computer end program and UDP mode is exactly the same, no need to change.
