3.4.5 UDP Server

(1) UDP Server means that the source IP address is not verified on the basis of ordinary UDP. After receiving a UDP packet, the

target IP is changed to the data source IP and port number. When the data is sent, the latest communication is sent. That IP and port

number.

(2) This mode is usually used for data transmission scenarios where multiple network devices need to communicate with the

module and do not want to use TCP due to faster speed.

Note: UDP Server cannot send data actively, and can only send data to the IP and port that has recently performed data interaction

after receiving the data.

→Wireless

(1) WOR is closed. The DTU works in the transmission mode, and the data input by the user through the Ethernet, the DTU will

initiate wireless transmission. The wireless receiving function is turned on, and the wireless data is received and output through the

Ethernet.

(2) WOR transmitter. The DTU is sent and received, and when the data is transmitted, a wake-up code is added for a certain period

of time.

(3) WOR receiver. The DTU cannot transmit data, works in the WOR listening mode, and the listening period is selected on the

web side. The longer the WOR listening interval period,

The lower the average power consumption, but the greater the data delay, the two sides must be consistent (very important).

It supports address function, the master can transmit data to any address, any channel module, to achieve networking, relay and

other application methods: for example: module A needs to send data to module B (address is 0x00 01, channel is 0x80) AA BB CC

The communication format is: 00 01 80 AA BB CC, where 00 01 is the module B address and 80 is the module B channel, then

module B can receive the AA BB CC (other modules do not receive data).
