Hi, i'm using arduino and SIM808 V3.2 for a project.
I ve already write the sketch for chek recived SMS and if it is a word that i choose ("STATO")
send an SMS.
I would like that the answer will be send not to a pre established number.
I wish to read the senders number and answer him.
Is it possible? How?
Here is my code right now
#include <SoftwareSerial.h>
// Configure software serial port
SoftwareSerial mySerial(10, 11);
// Variable to store text message
String textMessage;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Serial begin ok");
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
mySerial.println("AT");
}
void loop(){
ricezione();
delay(2000);
}
void ricezione(){
Serial.println ("controllo ricezione SMS");
// AT command to set mySerial to SMS mode
mySerial.print("AT+CMGF=1\r");
delay(100);
// Read the first SMS saved in the sim
mySerial.print("AT+CMGR=1\r");
delay(10);
if(mySerial.available()>0){
textMessage = mySerial.readString();
Serial.print(textMessage);
delay(10);
}
// check if the SMS is "STATO"
if(textMessage.indexOf("STATO")>=0){
Serial.println("Invio info stato arnia");
smsstato();
textMessage = "";
}
}
void smsstato(){
// delete the first SMS
mySerial.print("AT+CMGD=1\r");
delay(100);
mySerial.print("AT+CMGF=1\r");
delay(1000);
/i wish that phone number change with the phone number of the sender of SMS
mySerial.print("AT+CMGS=\"+39348395xxxx\"\r");
delay(1000);
//The text of the message to be sent.
mySerial.print("prova invio sms: ");
delay(1000);
mySerial.write(0x1A);
delay(1000);
}
Thank you very much!
