Arduino 用Xbee扩展板给HC-06蓝牙模块设置AT指令

/*

  A simple code snippet for setup AT commands
  for a Bluetooth HC-06 slave module.

  Procedure:

  1. Hardware preparation:
  Connect the right pins on the arduino sensor shield:
     DOUT(bluethooth) --> D2(MCU)
     DIN(bluetooth) --> D3 (MCU)

  2. Software preparation:
  Arduino 1.0.1 is needed to compile the code (For older versions,
  you may have to modify the 'SoftwareSerial' to 'NewSoftSerial').
  Make sure you have the module's default baud rate or the rate you set
  last time and fill it to blueToothSerial.begin(YOUR_BAUD_RATE_HERE)
  in function setupBlueToothConnection().

  Upload this snippet into the powered up module, it will be done.

    // The baud rate of AT serial interface should be the same value
    // since your last time configuration, otherwise the fllowing
    // sendBlueToothCommand's won't work. For those new HC-06 modules,

    // default baud rate is, you can just emumate from 1200~115200 :)
