Enabling an XBee Interface in the IDE

Let's first set up the IDE for the XBee that will be connected to the Galileo. Once you have connected the shield to the Galileo, simply connect the Galileo with the USB cable to your host computers. Bring up the IDE and then type in the following code into the sketch window:

Here is an explanation of this set of code:

• This set of code initializes the serial port on the Galileo, so you can receive via the serial interface:

  TTYUARTClass* gSerialStdPtr = &Serial; // Galileo, /dev/ttyGSO, Tx pin
  TTYUARTClass* gSerialTwoPtr = &Serial1; // Galileo, /dev/ttySO, Rx pin
  bool gGalileo = true;
  bool qData;
  int led = 13;

• This set of code starts the send and receive process, you'll only use the receive process for this application:

  qData = false; // Initialize on reset
  gSerialStdPtr->begin(9600); // Receiver
  gSerialTwoPtr->begin(9600); // Sender
  waitForUser(5); // Give usr time to open serial terminal
  gSerialStdPtr->println("XBee-Receiver-setup");
  pinMode...
