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.
- 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
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.
- 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. 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 compiliing by clicking button (->)
- Open serial monitor and set "\r\n " and "115200 baud "
- Firstly, you'll see notice of successful WIFI connection.
- If you see content description, it means you have visited "www.baidu.com".
