Download program Stacke mCookie-WiFi and mCookie-CoreUSB, plug USB cable into mCookie-CoreUSB on one side and connect computer USB socket on the other side. Then, start Arduino IDE, copy the program above to IDE, select Microduino-CoreUSB in (tools) -> (Board) and choose the right serial number in (tools) -> (Serial). After that, please click button (√) on the top left of IDE and compile the program. Burn the program to the board after compiling by clicking button (->); Open serial monitor and set "\r\n " and "115200 baud " The notice of successful WIFI connection will pop up at first. Enter AT instruction in the serial port and it will return "OK". Enter website such as baidu.com in the serial port and it will return webpage data. Serial Enter fixed instructions in the serial monitor and you'll see returned result, which can refer to common AT Instruction part. Such as: AT+GMR AT+CIFSR AT+CIPSTATUS AT IDE tests program You can adopt HTTPGET program of _03_microduino_WiFi_ESP8266 from Microduino IDE example for testing. Change your WIFI password in the code where there are SSID(WIFI name) and password setting.
