HLK-WIFI-M03 is the new third-generation embedded Uart-Wifi modules HLK-WIFI-M03 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-WIFI-M03 does a comprehensive hardware and software upgrades based on the products of the first two generations ,nowit'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 dynamic assignation of IP address and DNS domain name parsing. Support Embed WEB server, and achieve the long-range parameters configuration through wireless network with IE browser. Support more prefect transmission performance, the maximum sending rate can reach to 11KB/s.
