I can't power up GRPS Shiel SIM900 via software

[majodijo]

Hi,
I can't power up via software.
my sketch is:


#include <SoftwareSerial.h>
#include <String.h>
SoftwareSerial mySerial(7, 8);

void setup(){
mySerial.begin(19200);
delay(500);
powerUp();
}

void loop(){
}

void powerUp()
{
pinMode(9, OUTPUT);
digitalWrite(9,LOW);
delay(1000);
digitalWrite(9,HIGH);
delay(2000);
digitalWrite(9,LOW);
delay(3000);
}


is it correct?
thank's

void setup(){
mySerial.begin(19200);
delay(500);
//powerUp();
}

void loop(){
powerUp()}

void powerUp()
{
pinMode(9, OUTPUT);
digitalWrite(9,LOW);
delay(1000);
digitalWrite(9,HIGH);
delay(2000);
digitalWrite(9,LOW);
delay(3000);
}


Try it like this.
