Figure 3-3 UDP mode diagram

For UDP mode in Figure 3-3, W5500S2E-S1 module is required to have the remote IP address and

port number to create an UDP communication. UDP mode communicate is not based on

“connection”. Therefore, it does not guarantee the target device could receive the data correctly or

not. Thus, it requires an upper layer communication protocol to communicate for ensuring the data

accuracy. However, since UDP mode is a simple communication protocol, it could provide a better

communication speed due to less workload on data accuracy. In fact, UDP are not likely to get data

error in network environment under normal workload. In this operating mode, both devices are equal,

and they do not differentiate into server or client.

6 AT command configuration

W5500S2E-S1 supports AT command configuration method. This method could only apply when

W5500S2E-S1 is in command mode. User needs to send the AT serial command mentioned in this

section, W5500S2E-S1 could be modified by requirement. User could use serial terminal or MCU

main board that connected with W5500S2E-S1 for applying these configurations.

6.1 AT command overview

AT command is case insensitive. Except the “+++” command, all other commands are starting with

string “AT ”. These commands activate after received CRLF (Carriage-Return Line-Feed). This

means “\r\n” (“0x0d 0x0a” in HEX). These commands and related parameters are defined. Sending

wrong characters or sending in the inappropriate format will return an error.

AT commands have 4 types:

1. +++

Exit from data mode and changed to command mode.

2. Command without parameter

Format: AT+ <command>\r\n, No extra parameters or symbol after the command. For

example: AT+EXIT\r\n.

3. Query Command

Format: AT+<command>?\r\n, this kind of command is checking the command’s parameter

value. In example: AT+ECHO?\r\n.

4. Commands with parameter

Format: AT ＋<command>=<parameter1>,<parameter2>,<parameter3>…\r\n this will set the

command’s parameter value.

Based on users AT command inputs, W5500S2E-S1 will reply related return value. These

values included correct and error message as showed on the following 6-1 table.

6.2 Enter AT command Mode

W5500S2E-S1 has two modes, AT command mode and data mode. In AT command mode, user

could use serial terminal or through user’s MCU main board to configure the parameters of the

module. Command enter will return a value (In echo mode, it will show the serial message). In data

mode, all the commands except the “+++” would be ignored to the module. Thus, entering the “+++”

command will change the module into AT command mode.

Note: ”+++” command rules: It needs to send “+” symbol continuously in 3 times to through serial

interface to the module. This command requires 1 second gap each before and after this command

has entered to activate the correct response from W5500S2E-S1. If not, it will consider as user’s

data input. This command does not require CRLF (Carriage-Return Line-Feed)(\r\n). The factory
