BLE on/off LED with red bear BLE Nano Kit

[nolispe280]

Hi,

I am trying to use the red bear BLE nano kit but am having difficulties with the Arduino program. Prior to the red bear I used a standard Arduino and BLE module to switch an LED on and off with my phone. Using the simple Blink_ble example it was pretty straightforward:

#include <SoftwareSerial.h>

char junk;
String inputString="";

void setup()                    // run once, when the sketch starts
{
 Serial.begin(9600);            // set the baud rate to 9600, same should be of your Serial Monitor
 pinMode(13, OUTPUT);
}

void loop()
{
  if(Serial.available()){
  while(Serial.available())
    {
      char inChar = (char)Serial.read(); //read the input
      inputString += inChar;        //make a string of the characters coming on serial
    }
    Serial.println(inputString);
    while (Serial.available() > 0)  
    { junk = Serial.read() ; }      // clear the serial buffer
    if(inputString == "a"){         //in case of 'a' turn the LED on
      digitalWrite(13, HIGH);  
    }else if(inputString == "b"){   //in case of 'b' turn the LED off
      digitalWrite(13, LOW);
    }
    inputString = "";
  }
}

Unfortunately doing the same with the redbear board seems much trickier! I have tried modifying the SimpleChat example but unfortunately using Serial.read() in the void loop function does not work (the variable is not recognised)

Anyone has had a similar issue?
