HLK-WIIF-M04 is the new third-generation embedded Uart-Wifi modules studied by Shenzhen Hi-Link ElectronicTechnology co.,Ltd
Uart-Wifi is an embedded module based on the Uart serial,according with the WiFi wireless WLAN standards, It accords with IEEE802.11 protocol stack and TCP / IP protocol stack，and it enables the data conversion between the user serial and the wireless network module. through the Uart-Wifi module, the traditional serial devices can easily access to the wireless network.
HLK-WIIF-M04 does a comprehensive hardware and software upgrades based on the products of the first two generations,now it’s more functional and more Convenient to use,its main features include,
Support transparent transmission of serial completely,and achieve a plug and play serial.
Support new AT+instruction set,Which is all based on ASCII format, it’s simple to use and pellucid.
Support more perfect TCP/IP protocol tack, support DHCP protocol for dynamicassignation of IP address and DNS domain name parsing.
Embed WEB server, and achieve the long-range parameters configur -ation through wireless network with IE browser.
