Instrument, equipment parameter monitoring, wireless POS machine
Modern agriculture, military field and other wireless related secondary development applications
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.
Optimized low power wifi modules
Low power wifi modules are integrated 802.11b / g / n low-power embedded wifi modules.
It provides a solution to connect the physical device to wifi wireless network and transfer data by UART interface. It is widely used in those fields which need to transfer data with low flow and low frequency. e.g: smart home, smart electricity, medical monitoring, industrial control.
