1  Using Arduino / Programming Questions / Android ADK Blinking example not blinking sometimes on: October 05, 2012, 03:26:04 am
I have arduino uno connected with itead usbshield. I am receiving the data from android phone and it blinks only when i open serial monitor otherwise it is not. How to blink it independently. Is there any way it relates with opening serial monitor...?

I use pin 13 for blinking it...
Please guide me in to this...

This is the code...

Code:
void loop()
{
  Usb.Task();
  if(adk.isReady()) {
    uint8_t msg[1];
    uint16_t len = sizeof(msg);
    uint8_t rcode = adk.RcvData(&len, msg);
    if(rcode && rcode != hrNAK)
      USBTRACE2("Data rcv. :", rcode);
    if(len > 0) {
      Serial.print(F("\r\nData Packet: "));
      Serial.print(msg[0]);
      digitalWrite(LED,msg[0] ? HIGH : LOW);
    }
  }
  else
    digitalWrite(LED, LOW);
}
