What have you tried? DO you have any code?
thanks for your answer.
This is the code to send an sms.
#include <SoftwareSerial.h>
#define rxPin 9
#define txPin 8
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
char text[150];
String message="";
int i;
void setup(){
pinMode(10,OUTPUT);
Serial.begin(9600);
while (!Serial){}
mySerial.begin(9600);
digitalWrite(10,0);
delay(1000);
digitalWrite(10,1);
Serial.println("Write your SMS:");
}
void loop(){
i=0;
while( Serial.available()>0 ){
text = Serial.read(); *
_message += text; _
*i++; *
*if (text[i-1]==46){ *
_ Serial.println("Send SMS......"); _
_ SendTextMessage(); _
_ ShowSerialData(); _
_ delay(1000); _
_ Serial.println("\r");_
_ Serial.println("Success"); _
_ message=""; _
_ i=0; }}} *_
void SendTextMessage(){
mySerial.print("AT+CMGF=1\r");
*delay(1000); *
*mySerial.print("AT+CMGS="+491781234567"\r"); *
*delay(1000); *
*mySerial.println(message); *
*mySerial.print("\r"); *
*delay(1000); *
*mySerial.println((char)26); *
*mySerial.println(); } *
*void ShowSerialData(){ *
*while(mySerial.available()!=0) *
*Serial.write(mySerial.read());} *
now i have this code but nothing happened when i ride an sms with ON
i hope someone can help me
