/*****************
The commands sent to the bee have to be lower case
The commands sent to the bee do not start with \r\n as the BlueTooth Bee wiki state
This works with the DFRobot BlueToothBee ver 2.0  Tested and verified 11/13/13 on my personal M3PI and BTBee module
Additional commands can be found at:  http://www.dfrobot.com/image/data/TEL0026/TEL0026_Datasheet.pdf

Steps to success:
    1.Power off
    2.switch on bee to AT Mode
    3.Power on
    4.Download program to MBED
    5.Run MBED program
    6.Power off     settings in the bee are sent to ROM and will be retained after the power cycle
    7.Switch to !AT Mode
    8.Power On
