Development

• Program

File:ESP8266TestV1.zip

Change your WIFI password in the code where there are SSID(WIFI name) and password setting.

• 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

Change your WIFI password in the code where there are SSID(WIFI name) and password setting.

• Download program
  • Stack Microduino-WiFi(ESP) with Microduino-Core+ and Microduino-USBttl, plug USB cable into mCookie-CoreUSB on one side and connect computer USB socket on the other side.
