[brian25]

How to save the password in eeprom? when the device is turn off the pass was still in the chip.
and what syntax to use for changing the password?


tnx

char p1[] = {"11111"};

void Password(){

  char p2[5];
  int y = sizeof(p1);
  int flag=0;

  for (int x=0;x<=y;x++)
  {
    p2[x]= p1[x];
  }


  if(gsm.readSMS(smsbuffer, 5, p2, 5) == 0)
  flag=1;
  {
    if(strstr(smsbuffer,"11111") != NULL){
    Serial.println(strcmp(smsbuffer,"Matched"));
    }
    else if(strstr(smsbuffer," ") != NULL){
    flag=2;


  }
    }
  if(flag==2){    
    Serial.println(strcmp(smsbuffer,"Matched"));
    delF();
    }
    else if(flag==1){    
    Serial.println(strcmp(smsbuffer,"Don't Matched"));
    delF();

}
}

void delF()
{
 Serial.println("Executing delete");
     for (int j=0;j<=4;++j){     
     Serial.println(sms.DeleteSMS(j));
     }
}
