getIMEI return OK - not IMEI

[nishantpardamwar]

above fix didn't work for me, so i wrote my own funtion.

replace these two function in SIM900.cpp

int SIMCOM900::getIMEI(char *imei)
int SIMCOM900::SimpleRead()

with

int SIMCOM900::getIMEI(char *imei){
  //AT command to get IMEI.
  int i =0,a;
  unsigned long startTime = millis();
  char c;
  SimpleWriteln(F("AT+GSN"));
  while(true){
    a = SimpleRead();
    c = a;
    if(a!=-1){
      if(a == 13 && i==15){
        imei[15] = '\0';
        return 1;
      }
      if(a != 13 && a!= 10 && c!= 'O' && c!= 'K'){
        startTime = millis();
        imei[i] = c;
        i++;
      }
    }else if((millis() - startTime)>5000){
      return 0;
    }
  }
  return 0;
}   

int SIMCOM900::SimpleRead(){
  char datain;
  if(_cell.available()>0){
    datain=_cell.read();
    if(datain>0){
      return datain;
    }else
      return -1;
  }else
    return -1;
}
