Two-way Wi05 Series Serial to WIFI for packet forwarding, users do not care about the details, the completion of the internal protocol conversion module, serial data port side of the transparent transmission, WIFI network side is TCPIP packets by simply setting, you can set up Web pages inside the module can or also be carried out through the serial port using AT commands, once set up permanent preservation. 

WI05 module is an integrated 802.11 b/g/n Wi-Fi, low-power embedded Wi-Fi module, provides a way to connect the user's physical device to a Wi-Fi wireless networks and provide UART interface for data transfer solutions. With this module, the traditional low-end MCU control serial device or devices can easily access Wi-Fi wireless networks, in order to achieve things together network control and management. 

The module integrates hardware MAC, baseband chip, RF transceiver unit, and a power amplifier; embedded firmware supports Wi-Fi protocol and configuration, as well as networking, TCP / IP protocol stack. 

WI05 using the industry's lowest-power embedded architecture design, and for smart grids, smart application of handheld devices, personal medical, industrial control, etc, these low-flow low-frequency field of data transmission, we did make professional optimization for these fields.

* pin 8, 9, 10 can used as PWM or GPIO function, set AT+LPTIO=on for this function.
* Only use 3V3 for all the logic pins, and 3v3 power pins, higher volt may break the module.

== Module working mode ==
''' UART communication mode '''
* Commands mode (AT)
* To enter into the AT commands mode, type +++ (+ three times), the module will return a confirmation code "a", then type "a" you will have "+ok" return, and now the module enter into AT mode. This commands charachters must enter within 300 ms in between them.

* AT commands list
* enqiry format example, AT+WMODE
* Set format example, AT+WMODE=AP
* Commands end up with <CR> carriage return.
* Can use secureCRT serial tool, default settings as the picture shown below
