I am from chennai and i am trying to send sms using Arduino using the SIM300 Module done by gsmmodemindia.com, but their webpage is not working and the SIM300 module is same as in this web page... **broken link removed**
I have connected the RX-RX, TX-TX, 3.3V of Arduino to 3.6V of the Sim Board and GND-GND... i even tried crossing over the RX and TX
and this is my simple program
#include <OneWire.h>
#include <Wire.h>
void setup() {
Wire.begin();
Serial.begin(9600);
delay(1000);
Serial.println("");
Serial.print("AT+CMGF=1"); //set to SMS mode
Serial.print(13,BYTE);
Serial.print(10,BYTE);
delay(1000);
Serial.print("AT+CMGS=\"9884044647\""); //set the phone number (wrapped in double quotes)
Serial.print(13,BYTE); //Carriage return and line feed
Serial.print(10,BYTE);
delay(1000);
Serial.print("hello world");
Serial.print(26,BYTE); //'ctrl+z' or 'SUB'
delay(2000);
Serial.print(13,BYTE); //Carriage return and line feed
Serial.print(10,BYTE);
//Second attempt.......
Serial.flush();
delay(3000);
Serial.println("AT+CMGF=1"); //set to SMS mode
delay(1000);
Serial.println("AT+CMGS=\"9884387877\""); //set the phone number
delay(3000);
Serial.print("hello world2");
Serial.print(26,BYTE); //'ctrl+z' or 'SUB'
Serial.println("");
}
void loop () {
}
////////////////////////////
still no response.. is there something that i am doing wrong? or what can be done to get it going.
I want to transmit my aquarium parameters to my mobile regularly... it is a reef aquarium.
Your help is much appreciated..
thanks
