Merging two arduino sketches - arduino

Question

I have been working on a project. I have two sketches. One is to get GPS location and one is send location via SMS (GSM Module). I want to combine both sketches.
GPS sketch:
#include <SoftwareSerial.h>
#include <TinyGPS.h>
//long lat,lon; // create variable for latitude and longitude object
float flat, flon;
SoftwareSerial gpsSerial(4, 3); // create gps sensor connection
TinyGPS gps; // create gps object
void setup(){
Serial.begin(9600); // connect serial
gpsSerial.begin(9600); // connect gps sensor
}
static void print_float(float val, float invalid, int len, int prec)
{
if (val == invalid)
{
while (len-- > 1)
Serial.print('*');
Serial.print(' ');
}
else
{
Serial.print(val, prec);
int vi = abs((int)val);
int flen = prec + (val < 0.0 ? 2 : 1); // . and -
flen += vi >= 1000 ? 4 : vi >= 100 ? 3 : vi >= 10 ? 2 : 1;
for (int i=flen; i<len; ++i)
Serial.print(' ');
}
// smartdelay(0);
}
void loop(){
while(gpsSerial.available()){ // check for gps data
if(gps.encode(gpsSerial.read())){ // encode gps data
// gps.get_position(&lat,&lon); // get latitude and longitude
gps.f_get_position(&flat, &flon);
String lat = String(flat,6);
String lon = String(flon,6);
Serial.print(lat);
Serial.print(' ');
Serial.println(lon);
}
}
}
GSM sketch:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(9, 10);
void setup()
{
mySerial.begin(9600); // Setting the baud rate of GSM Module
Serial.begin(9600); // Setting the baud rate of Serial Monitor (Arduino)
delay(100);
}
int index=0;
long dlat=0,dlong=0;
char st[256],st1[256],st2[256];
void RecieveMessage()
{
mySerial.println("AT+CNMI=2,2,0,0,0"); // AT Command to receive a live SMS
// mySerial.println("cheking");
// mySerial.println(string);
}
void loop()
{
if (Serial.available()>0)
RecieveMessage();
if (mySerial.available()>0)
{
//int st;
st[index++] = mySerial.read();
//Serial.write(st[index-1]);
if(index>=51&&index<=63){
st1[index-51]=st[index-1];
Serial.write(st1[index-51]);
}
if(index>=65&&index<=77){
st2[index-65]=st[index-1];
Serial.write(st2[index-65]);
}
/*if(index==77)
{
int i=0;
mySerial.print(st1);
for(i=0;i<13;i++)
{
if(st1[i]!='.')
dlat=dlat*10+(st1[i]-'0');
if(st2[i]!='.')
dlong=dlong*10+(st2[i]-'0');
//Serial.print(dlat);
}
//Serial.print(dlat);
//Serial.print(" ");
//Serial.print(dlong);
*/
}
}
I want to merge these two sketches so that I can send location via GSM sketch and receive location through GPS sketch.
Any help will be appreciated.
Thanks.

The following way you can merge your two sketches :
#include <AltSoftSerial.h>
#include <SoftwareSerial.h>
#include <TinyGPS.h>
//long lat,lon; // create variable for latitude and longitude object
float flat, flon;
SoftwareSerial gpsSerial(4, 3); // create gps sensor connection
TinyGPS gps; // create gps object
static const int RXPin = 8, TXPin = 9;
AltSoftSerial mySerial(RXPin, TXPin);
int index=0;
long dlat=0,dlong=0;
char st[256],st1[256],st2[256];
void RecieveMessage()
{
mySerial.println("AT+CNMI=2,2,0,0,0"); // AT Command to receive a live SMS
// mySerial.println("cheking");
// mySerial.println(string);
}
void setup(){
Serial.begin(9600); // connect serial
gpsSerial.begin(9600); // connect gps sensor
mySerial.begin(9600); // Setting the baud rate of GSM Module
delay(100);
}
static void print_float(float val, float invalid, int len, int prec)
{
if (val == invalid)
{
while (len-- > 1)
Serial.print('*');
Serial.print(' ');
}
else
{
Serial.print(val, prec);
int vi = abs((int)val);
int flen = prec + (val < 0.0 ? 2 : 1); // . and -
flen += vi >= 1000 ? 4 : vi >= 100 ? 3 : vi >= 10 ? 2 : 1;
for (int i=flen; i<len; ++i)
Serial.print(' ');
}
// smartdelay(0);
}
void loop(){
while(gpsSerial.available()){ // check for gps data
if(gps.encode(gpsSerial.read())){ // encode gps data
// gps.get_position(&lat,&lon); // get latitude and longitude
gps.f_get_position(&flat, &flon);
String lat = String(flat,6);
String lon = String(flon,6);
Serial.print(lat);
Serial.print(' ');
Serial.println(lon);
if (Serial.available()>0)
RecieveMessage();
if (mySerial.available()>0)
{
//int st;
st[index++] = mySerial.read();
//Serial.write(st[index-1]);
if(index>=51&&index<=63){
st1[index-51]=st[index-1];
Serial.write(st1[index-51]);
}
if(index>=65&&index<=77){
st2[index-65]=st[index-1];
Serial.write(st2[index-65]);
}
/*if(index==77)
{
int i=0;
mySerial.print(st1);
for(i=0;i<13;i++)
{
if(st1[i]!='.')
dlat=dlat*10+(st1[i]-'0');
if(st2[i]!='.')
dlong=dlong*10+(st2[i]-'0');
//Serial.print(dlat);
}
//Serial.print(dlat);
//Serial.print(" ");
//Serial.print(dlong);
*/
}
}
}
}
P.S : I have changed the pins for GPS and rest part is same irrespective of adding AltSoftSerial it is a library same as SoftwareSerial (Download it from manage libraries and it requires pins 8 and 9)
