Hi there, I have a little problem with my code!
I'm a student so I'm not really good with arduino.
I wanted to do use arduino to receive gps data (longitude/latitude) and send it by sms to my mobile phone!
It's almost perfectly working here is what I receive :
"Voici la longitude : // in english : "Here is longitude :
Longitude
Voici la latitude : // in english "Here is latitude :
Latitude*,Longitude*** "
The second longitude is the problem! I don't want to receive it twice! I'm always trying to change my code, but it never works i'm always receiving this message, except if I remove the ligne of longitude in the code, then I receive my Latitude and only my latitude!
By the way, i'm directly sending char, is that a problem? My teacher said it was strange to send char, but it instantly worked, and when I was trying to do : char=>string/int... it never worked!
So here is my code, if someone nice could explain me why it sends 2 times longitude, (I think it's an easy problem) Thank's, WinTos.
#include <SoftwareSerial.h>
SoftwareSerial GPS(2, 3);
unsigned char buffer[84]; // buffer array for data receive over serial port (84 car longueur trame = 74 et faut que ce soit >74)
int count=0; //compteur pour réinitialiser les valeurs du gps
char Latitude[10];
char Longitude[10];
// counter for buffer array
void setup()
{
GPS.begin(9600); // the SoftSerial baud rate
Serial.begin(9600); // the Serial port of Arduino baud rate.
Serial.println("AT+CMGF=1");
}
void sendInfo()
{
Serial.print("AA");
delay(1000); //delay of 1
Serial.println("AT");
delay(1000);
Serial.write("AT+CMGF=1\r\n"); //set GSM to text mode
delay(1500);
Serial.write("AT+CPMS="SM"\r\n"); //Preferred SMS Message Storage
delay(1000);
Serial.write("AT+CMGS="+3375791187"\r"); //set GSM to text mode
delay(1500);
Serial.println("Voici la longitude : ");//avant cetait latitude
Serial.println(Longitude);
Serial.println("Voici la latitude : "); // avant cetait longitude
Serial.println(Latitude);//set GSM to text mode
delay(1500);
Serial.write(0x1A); // sends ctrl+z end of message
delay(1500);
Serial.println("sms sent ");
} //end sendInfo()
void loop()// debut loop

for (int j=0; j<10;j++) // compteur de 0 à 10 de 1 en 1 il lit les 10 caractères, mais 10 fois les memes a chaque fois donc faut clear buffer
{ // remplissage long et lat
Longitude[j]=buffer[j+30];// Commence à 30 caractères, saute GPGGA, et heure, longitude, N, etc...
}
count = 0;
for (int u=0; u<10;u++)
{
Latitude[u]=buffer; //Commence à 18 caractères, saute Gpgga,et heure temps universelle
} // fin remplissage long et lat
} // fin if gps
delay(1000); //délai de 20minutes = (1200000) 9 messages durant ascenscion théorique
count = 0; //revient à 0 pour pas afficher les memes trucs en boucle

}
void clearBufferArray() // function to clear buffer array
{
for (int i=0; i<count;i++)
