Hi friends, this is my first time posting here,
I am trying to put together a project that will read some text from a website and display it on Serial Monitor using GPRS shield V2.0 that i bought from seeedstudio.
This is my Code:
#include <SoftwareSerial.h>
#include <String.h>
SoftwareSerial mySerial(7, 8);
void setup()
{
mySerial.begin(19200); // the GPRS baud rate
Serial.begin(19200); // the GPRS baud rate
delay(500);
}
void loop()
{
//after start up the program, you can using terminal to connect the serial of gprs shield,
//if you input 't' in the terminal, the program will execute SendTextMessage(), it will show how to send a sms message,
//if input 'd' in the terminal, it will execute DialVoiceCall(), etc.
if (Serial.available())
switch(Serial.read())
{
case 't':
SendTextMessage();
break;
case 'd':
DialVoiceCall();
break;
case 'h':
SubmitHttpRequest();
break;
}
if (mySerial.available())
Serial.write(mySerial.read());
}
///SendTextMessage()
///this function is to send a sms message
void SendTextMessage()
{
mySerial.print("AT+CMGF=1\r"); //Because we want to send the SMS in text mode
delay(100);
mySerial.println("AT + CMGS = \"+6285710020395\"");//send sms message, be careful need to add a country code before the cellphone number
delay(100);
mySerial.println("nge cek brow !!!");//the content of the message
delay(100);
mySerial.println((char)26);//the ASCII code of the ctrl+z is 26
delay(100);
mySerial.println();
}
///DialVoiceCall
///this function is to dial a voice call
void DialVoiceCall()
{
mySerial.println("ATD + +6285710020395;");//dial the number
delay(100);
mySerial.println();
}
///SubmitHttpRequest()
///this function is submit a http request
///attention:the time of delay is very important, it must be set enough
void SubmitHttpRequest()
{
mySerial.println("AT+CSQ");
delay(100);
ShowSerialData();// this code is to show the data from gprs shield, in order to easily see the process of how the gprs shield submit a http request, and the following is for this purpose too.
mySerial.println("AT+CGATT?");
delay(100);
ShowSerialData();
mySerial.println("AT+SAPBR=3,1,\"CONTYPE\",\"GPRS\"");//setting the SAPBR, the connection type is using gprs
delay(1000);
ShowSerialData();
mySerial.println("AT+SAPBR=3,1,\"APN\",\"XL-INTERNET\"");//setting the APN, the second need you fill in your local apn server
delay(4000);
ShowSerialData();
mySerial.println("AT+SAPBR=1,1");//setting the SAPBR, for detail you can refer to the AT command mamual
delay(2000);
ShowSerialData();
mySerial.println("AT+HTTPINIT"); //init the HTTP request
delay(2000);
ShowSerialData();
mySerial.println("AT+HTTPPARA=\"URL\",\"http://kitaselamanya-d3tt3402.netne.net/runningtext/proses.php?infonya=hello\"");// setting the httppara, the second parameter is the website you want to access
delay(1000);
ShowSerialData();
mySerial.println("AT+HTTPACTION=0");//submit the request
delay(10000);//the delay is very important, the delay time is base on the return from the website, if the return datas are very large, the time required longer.
//while(!mySerial.available());
ShowSerialData();
mySerial.println("AT+HTTPREAD");// read the data from the website you access
delay(300);
ShowSerialData();
mySerial.println("");
delay(100);
}
void ShowSerialData()
{
while(mySerial.available()!=0)
Serial.write(mySerial.read());
}
The problem I have is, what should i do with the code if i want change this code proses.php?infonya=hello with another info that i input from my website here :
http://kitaselamanya-d3tt3402.netne.net/runningtext
this is the code that i want to change :
mySerial.println("AT+HTTPPARA=\"URL\",\"http://kitaselamanya-d3tt3402.netne.net/runningtext/proses.php?infonya=hello\"");// setting the httppara, the second parameter is the website you want to access
delay(1000);
Any help would be much appreciated. Thank You
