I use Arduino mego 2560 and esp8266 follow this http://ift.tt/2maYGhD and write this code:
void setup() {
Serial.begin(9600);
Serial1.begin(115200);
}
void loop() {
Serial1.println("AT");
delay(1000);
Serial1.println("AT+CWMODE=1");
delay(1000);
Serial1.println("AT+CWJAP=\"SSSD\",\"PASSWORD\"");
delay(5000);
Serial1.println("AT+CIPSTART=\"TCP\",\"www.mywebsite.com\",80");
delay(1000);
Serial1.print("AT+CIPSEND=");
String postRequest ="GET /nhap.php HTTP/1.1\r\n\r\nHost:http://www.mywebsite.com\r\n\r\nConnection:close\r\n\r\n";
Serial1.println(postRequest.length());
delay(5000);
Serial1.println("GET /nhap.php HTTP/1.1");
Serial1.println("Host: www.mywebsite.com");
Serial1.println("Connection:close");
Serial1.println();
int check_down = 0;
String content = "";
while(Serial1.available()!=0)
{
check_down++;
content = content + String(char (Serial1.read()));
}
Serial.println(check_down);
//Serial.println(content);
Serial.println(content.substring(10,50));
delay(3000);
Serial1.println("AT+CIPCLOSE");
ShowSerialData();
delay(1000);
}
void ShowSerialData()
{
while(Serial1.available())
Serial.write(Serial1.read());
while (Serial.available())
Serial1.write(Serial.read());
}
My website:
<html>
<head></head>
<body>HELLO</body>
</html>
I want to get "HELLO" on serial monitor from arduino IDE but I got this:
AT+CIPCLOSE busy s...
SEND OK

??? @@ so something wrong between mega2560(9600) and esp8266(115200) ?
