gsm receiving sms help

Using Arduino Programming Questions
#1

im new to the whole arduino world but i have been messing around with examples.
I have a tinysine gsm sim900 module and im wanting to receive texts but every example i have found and tried to use does not work. the example located here (http://arduino.cc/en/Tutorial/GSMExamplesReceiveSMS#.UxE-lvldWSo) gives me this error when i check the code.

sketch_feb28a:60: error: ‘sms’ was not declared in this scope

and “GSM_SMS sms;” is highlighted in the code

GSM_SMS is not located in my libraries

anyone have any other code i could try?

post your code?
did you import the library?

i was able to get texts using the following code, and use AT command AT+CMGL=“ALL” to receive my messages.

#include <SoftwareSerial.h>
#include <string.h>

char incoming_char = 0;
SoftwareSerial cell(2,3);

void setup()
{
// Initialize serial ports for communication.
Serial.begin(9600);

// Reset
Serial.println(“Start Reset”);
pinMode(7, OUTPUT);
digitalWrite(7, HIGH);
delay(12000);
digitalWrite(7, LOW);
delay(1000);
Serial.println(“End Reset”);

cell.begin(9600);

Serial.println(“Enter your AT commands (with CR & NL)…”);
}

void loop()
{
if(cell.available() > 0)
{
incoming_char = cell.read();
if((incoming_char >= ’ ') && (incoming_char<=‘z’))
Serial.print(incoming_char);
else
{
Serial.print("%");
Serial.print((int) incoming_char);
Serial.print("%");
if(incoming_char == 10)
Serial.println();
}
}

if(Serial.available() > 0)
{
incoming_char = Serial.read();
cell.print(incoming_char);
}
}

Please use [code] tags, and it looks like you didn’t declare the GSM library.
Have a look at this page:
http://forum.arduino.cc/
Read all the libraries, use those instead, since your code seems to be using Serial…
If you want to use your own,
Add to the top of your code:

#include <GSM.h>

and add below that these lines:

GSM gsmAccess;
GSM_SMS sms;

Try it now.
