smeisel 2:d0adbf94c4c0 29 The commands sent to the bee have to be lower case
smeisel 2:d0adbf94c4c0 30 The commands sent to the bee do not start with \r\n as the BlueTooth Bee wiki state
smeisel 2:d0adbf94c4c0 31 This works with the DFRobot BlueToothBee ver 2.0 Tested and verified 11/13/13 on my personal M3PI and BTBee module
smeisel 2:d0adbf94c4c0 32 Additional commands can be found at: http://www.dfrobot.com/image/data/TEL0026/TEL0026_Datasheet.pdf

smeisel 2:d0adbf94c4c0 34 Steps to success:
smeisel 2:d0adbf94c4c0 35 1.Power off
smeisel 2:d0adbf94c4c0 36 2.switch on bee to AT Mode
smeisel 2:d0adbf94c4c0 37 3.Power on
smeisel 2:d0adbf94c4c0 38 4.Download program to MBED
smeisel 2:d0adbf94c4c0 39 5.Run MBED program
smeisel 2:d0adbf94c4c0 40 6.Power off settings in the bee are sent to ROM and will be retained after the power cycle
smeisel 2:d0adbf94c4c0 41 7.Switch to !AT Mode
smeisel 2:d0adbf94c4c0 42 8.Power On
