4.2.3 UDP Server mode

UDP Server is a device that enables a device to communicate with a UDP protocol without

verifying the data source IP address, and after each UDP packet is received, the source IP address of

the packet and the source port are saved and set to the target IP and port, so the device The data

sent by sends packets only to the source IP address and port where the last device received the data.

This mode is typically used for scenarios where multiple network devices communicate with

this device and are more frequent and TCP Server

Note: InUDP mode, the network should send data to the device less than 512Bit per pack,

otherwise data loss will result.

UDP Client is a connectionless transport protocol that provides a simple, unreliable information

delivery service for transactions, with no connection established and disconnected, and only IP and

ports need to be developed to send data to each other. Typically used for data transfer scenarios

where packet drop rates are not required, packets are small and send more frequently, and data is

passed to the specified IP.

In UDP Client mode, the device will only communicate with the target port of the target IP, and

data sent by other IPs will not be received by the device.

In this mode, the destination address is set to 255.255.255.255,and the sending data is broadcast

throughout the network segment, but the transceiver device needs to ensure that the ports are

consistent and that the device can also receive broadcast data.

The basic parameters of serial port include: baud rate, data bit, stop bit, check bit.

Baud Rate: Serial communication rate, configurable for

1200,2400,4800,9600,14400,19200,38400,57600,115200 、230400bps。

Data bits: The length of the data bits, range 5,6,7,8.

Stop bit: You can set ranges 1,2.

Check bit: the check bit of data communication, support None,Odd,Even,Mark,Space five

verification methods by setting serial parameters, to maintain consistent with serial connection

cannot meet the criteria.
