The development board USB socket provides both power and serial communications with the module. Ezurio provide a specialized terminal
program called Ezurio terminal but you can use your preferred terminal program in its place. This example uses the Microsoft Bluetooth stack and
software that comes with Windows XP SP and later. If your computer already has a different Bluetooth stack and software installed, such as
Widcomm or Toshiba, you may need to disable or remove it before continuing. Alternative you can modify the computer aspect of the procedure
below to match your existing stack and use the computers built in Bluetooth instead of the BRBLU0300-010A0.
