I work with GSM shield sim900 with u-blox GPS sheiled and i could not join two codes with each other to send a location via sms
the gps code is:
//at 9600 bps 8-N-1
//Computer is connected to Arduino/Crowduino
//SoftSerial Shield is connected to the Software UART:D2&D3
#include <SoftwareSerial.h>
SoftwareSerial SoftSerial(6, 7);
unsigned char buffer[256]; // buffer array for data recieve over serial port
int count=0; // counter for buffer array
void setup()
{
SoftSerial.begin(9600); // the SoftSerial baud rate
Serial.begin(9600); // the Serial port of Arduino baud rate.
}
void loop()
{
if (SoftSerial.available()) // if date is comming from softwareserial port ==> data is comming from SoftSerial shield
{
while(SoftSerial.available()) // reading data into char array
{
buffer[count++]=SoftSerial.read(); // writing data into array
if(count == 256)break;
}
Serial.write(buffer,count); // if no data transmission ends, write buffer to hardware serial port
clearBufferArray(); // call clearBufferArray function to clear the storaged data from the array
count = 0; // set counter of while loop to zero
}
if (Serial.available()) // if data is available on hardwareserial port ==> data is comming from PC or notebook
SoftSerial.write(Serial.read()); // write it to the SoftSerial shield
}
void clearBufferArray() // function to clear buffer array
{
for (int i=0; i<count;i++)
{ buffer[i]=NULL;} // clear all index of array with command NULL
}

and the GSM code is:
#include "SIM900.h"
#include <SoftwareSerial.h>
//If not used, is better to exclude the HTTP library,
//for RAM saving.
//If your sketch reboots itself proprably you have finished,
//your memory available.
//#include "inetGSM.h"
//If you want to use the Arduino functions to manage SMS, uncomment the lines below.
#include "sms.h"
SMSGSM sms;
//To change pins for Software Serial, use the two lines in GSM.cpp.
//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.
//Simple sketch to send and receive SMS.
int numdata;
boolean started=false;
char smsbuffer[160];
char n[20];
//debug begin
char sms_position;
char phone_number[20]; // array for the phone number string
char sms_text[100];
int i;
//debug end
void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(4800))
{
Serial.println("\nstatus=READY");
started=true;
}
else
Serial.println("\nstatus=IDLE");
if(started)
{
//Enable this two lines if you want to send an SMS.
if (sms.SendSMS("0795647528", "Arduino SMS"))
Serial.println("\nSMS sent OK");
//if NO SPACE ,you need delte SMS from position 1 to position 20
//please enable this four lines
//for(i=1;i<=20;i++)
//{
//sms.DeleteSMS(i);
//}
}
};
void loop()
{
if(started)
{
//Read if there are messages on SIM card and print them.
sms_position=sms.IsSMSPresent(SMS_UNREAD);
if (sms_position)
{
// read new SMS
Serial.print("SMS postion:");
Serial.println(sms_position,DEC);
sms.GetSMS(sms_position, phone_number, sms_text, 100);
// now we have phone number string in phone_num
Serial.println(phone_number);
// and SMS text in sms_text
Serial.println(sms_text);
}
else
{
Serial.println("NO NEW SMS,WAITTING");
}
delay(1000);
}
};
