Various parameter setting method
Download settings software, search WiFi Modules in the LAN through the serial port server IP, name, MAC address, or the version number. Then set the parameters you need, otherwise keep the default.
1.Open your browser and inter the default IP address of the WiFi Modules.
2.Open the login page of Serial Server, Enter the user name and password (default admin).
3.After setting parameter, Click â€œSaveâ€œ and â€œRestartâ€œ, then setting will take effect.
Serial AT commands Settings
User can set parameter by module itself without going through another computer to configure. This setting method is used in the following situation: user have to configure IP address and destination IP address on site. AT command can meet the demand. After MCU connects serial server module by TTL (UART), MCU can configure setting by AT command.
