Thanks to Rick at esoftserve.com for posting the easy to follow demo code included below. Additional resources for Bluetooth Bee and XBee Shield
Parts List
– Arduino (tested using Uno R3, Mega and other versions also compatible)
– XBee Shield
– Bluetooth Bee
– A-B Usb cable
– Phone/computer with Bluetooth
– Bluetooth terminal program for testing connection and running sample commands (I used blueterm for Android)
Initial Bluetooth Bee (BtB) Setup Sketch
Only necessary for initial setup of your BtB. Be sure to remove XBee shield prior to uploading or you’ll get errors.
/*
One-time setup for a new Bluetooth Bee (BT Bee).
Only inquiry should be needed to connect after setup.
This sketch assumes that you are using:
1. the BT Bee and XBee Shield
2. pins 0/1 for RX/TX
3. dip switches on the XBee Shield should be
set right/right, to run the sketch
Sequence for uploading a sketch that expects the BT Bee:
1. Remove the BT Bee before uploading a sketch
2. Upload the sketch
3. Attach the BT Bee/XBee Shield
4. Reset the Arduino
In this sketch, a test app runs which accepts
characters from a terminal program:
a returns 'connected' to the host
h turns on LED on pin 13
l turns off LED on pin 13
This program was modified from the program found at
http://garden.seeedstudio.com/index.php?title=Bluetooth_Bee:
pins 0/1 are used for RX/TX instead of the NewSoftSerial library
For reference:
Leds on BT Bee:
blinking green = connected
double-blink green = not connected
green-red blinking = pairing/inquiring
Leds on XBee Shield
green = power
red =connected

Bluetooth Application Template Sketch
Code below is the basic template for using your bluetooth connection in your own custom applications. Note – must have completed initial setup of BtB prior to using code below.
/*
A template sketch for using the Bluetooth Bee (BT Bee) in your own app.
This sketch does not setup the BT Bee, it only attempts
to connect to the host. Use the BTBee_setup sketch first to set
defaults on the BT Bee you are using. After setup, only inquiry is
needed to initiate a BT connection as the sketch demonstrates.
This sketch assumes that you are using:
1. the Bluetooth Bee and XBee Shield
2. pins 0/1 for RX/TX
3. dip switches on the XBee Shield should be
set right/right, to run the sketch
