Seeed Grove BLE with Intel Edison UART (2 way serial)

Simple Grove BLE example

int incomingByte = 0;   // for incoming serial data

const int pinButton = 6;                        // pin of button define here
const int pinLed    = 3;                        // pin of led define here

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);

  Serial.println("hello");
  
    pinMode(pinButton, INPUT);                  // set button INPUT
    pinMode(pinLed, OUTPUT);                    // set led OUTPUT
    setupBleConnection();

}

void setupBleConnection()
{
  Serial1.begin(9600); //Set BLE BaudRate to default baud rate 9600
  Serial1.print("AT+CLEAR"); //clear all previous setting
  Serial1.print("AT+ROLE0"); //set the bluetooth name as a slaver
  Serial1.print("AT+SAVE1");  //don't save the connect information
}

void loop ()
{
  char recvChar;
  
  while(1)
  {
    if(Serial.available())
    {
       recvChar = Serial.read();
       Serial1.print(recvChar);
       digitalWrite(pinLed, HIGH);             // led on
    }
    
    if(Serial1.available())
    {
       recvChar = Serial1.read();
       Serial.print(recvChar);
       digitalWrite(pinLed, HIGH);             // led on
      
    }
    
    digitalWrite(pinLed, LOW);             // led off
  }
