Arduino WiFi Wireless Programming SKU TEL0107 Introduction The WiFi Bee MT7681 is an Arduino WiFi XBee module based on the MT7681 serial Wi-Fi module. It is compatible with an XBee slot, supports Arduino wireless programming and is ideal for Internet of Things IoT , home automation and robotics applications. The WiFi Bee supports the IEEE802.11b/g/n standard protocols, with 2.4G Wi-Fi bands, 14 channels and WEP/WPA-PSK/WPA2-PSK/TKIP/AES encryption methods, compatible with many mainstream routers. It has STA and AP working modes, is free to switch, and supports TCP/IP communications. In addition the WiFi Bee also supports SmartLink intelligent connection. The unit is easy to use - just install the app Android , and connect to your wireless router. The WiFi Bee has same pin mappings as an XBee. It can be inserted in any device which has an existing XBee socket for full networking capability. For Arduino UNO and Arduino Mega2560 boards, the WiFi Bee can also be used as a wireless code upload module eliminating the need for a USB cable or physical connection. This is very convenient when debugging robots or mobile platforms. In addition the module breakouts include three I/O ports. Use it as a Wi-Fi remote control - each I/O supports software PWM outputs. You can configure the parameters using serial AT commands via the serial terminal. • Support IEEE802.11b/g/n Protocol • Support WEP/ WPA-PSK/ WPA2-PSK/ TKIP/ AES Multiple Encryption Methods • Support STA/ AP Operating Mode • Support Arduino Wi-Fi Wireless Programming • Support SmartLink intelligent Connection function • Support OTA Firmware Upgrade Specification • Microcontrollers MT7681 • Protocol Standard IEEE802.11b / g / n • Wi-Fi Radius 180m different environment, different transmission distance • Number of channels 1-14 • Frequency range 2.4-2.4835G • Transmit power 15-18dbm • Encryption Method WEP / WPA-PSK / WPA2-PSK / TKIP / AES • Operating Mode STA mode / AP mode STA & AP mixed mode is not supported, only one device can be connected under AP mode • TCP 1000 port TCP <-> UART data transparent port • TCP 1001 port AT command port • UDP 3333 port broadcast port • Operating Voltage 3.3V • Recommended Input Voltage 3.3V • Power Consumption 75 mA • UART serial port 1 • Baud rate 9600, 14400, 19200, 38400, 57600, 115200bps default • Dimension 32 * 24 mm • Weight 3.5g Board Overview Label Name GPIO 0 GPIO 1 GPIO 2 RESET Arduino Reset WIFI Reset WiFi Reset Description 3.3V only GIPO 0 GIPO 1 GIPO 2 GND Reuse with GPIO 0, Arduino Reset Pin Reset WiFi Only WiFiBee Wireless Network Configuration WiFiBee-MT7681 supports STA and AP mode.

Introduction

The WiFi Bee MT7681 is an Arduino WiFi XBee module based on the MT7681 serial Wi-Fi module. It is compatible with an XBee slot, supports Arduino wireless programming and is ideal for Internet of Things IoT , home automation and robotics applications. The WiFi Bee supports the IEEE802.11b/g/n standard protocols, with 2.4G Wi-Fi bands, 14 channels and WEP/WPA-PSK/WPA2-PSK/TKIP/AES encryption methods, compatible with many mainstream routers. It has STA and AP working modes, is free to switch, and supports TCP/IP communications. In addition the WiFi Bee also supports SmartLink intelligent connection.

•

Open DFRobot IoT Manager, Select SSID ouki, Enter WiFi Password
•

Click ‘’‘Start Connection’‘’
• Wait for some seconds, when the LED flashes slowly 2/s , it means it has been connected to the

Configure the wireless network parameters via AT command

WiFi Bee also supports AT Command configuration, you can use the Xbee USB Adapter to connect WiFi Bee. If you have a DFRobot Leonardo with Xbee socket, you can achieve the same purpose with following debugging code. Note Since Uno has only one serial port, it doesn't support the same method, but you can check the next chapter.
void setup // put your setup code here, to run once Serial.begin 115200 Serial1.begin 115200 while !Serial ;
void loop // put your main code here, to run repeatedly:
while Serial.available Serial1.write Serial.read ;
while Serial1.available Serial.write Serial1.read ;
