3.4.3 The UDP Server mode

UDP Server Means that the device does not verify the data source IP address when communicating with the UDP protocol.

After you receive each UDP packet, save the source IP address and the source port and set it as the target IP and port, so the data

sent by the device only sends the packet to the source IP address and port of the last time that the device receives the data.

This mode is usually used for scenarios where multiple network devices communicate with the device and the frequency is

high and TCP Server cannot meet the conditions.

Using UDP Server requires the remote UDP device to send the data first, otherwise the data cannot be sent

normally.

[Note] In UDP mode, the network should send data to the device less than 512 Bit per package, otherwise it will cause data loss.

UDP Client A non-connected transmission protocol that provides a simple and unreliable information transmission service

oriented to transactions. Without connection establishment and disconnection, it only needs to configure the destination IP and

destination port to send the data to the other party. It is usually used for data transfer scenarios with no requirements for packet

loss rate, small packets and fast transmission frequency, and data to be transmitted to the specified IP.
