1 Introduction
TLG10UA03 is the new third-generation embedded Uart-Wifi modules studied by CEC
Huada Electronic Design Co., Ltd (here in after referred to as HED). Uart-Wif 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.
