2.  History
 Getting Started
 Connecting to the outside world
 Barcode scanner eBay app demo
 Other apps
 Q&A

3.  Using Classic Bluetooth
 Serial Port Profile
 Take advantage of the Arduino community
 Limited by your own imagination
 Increase shields
 Easier to get up and running than iOS

4.  Bluetooth History
 Android 1.5 – Bluetooth APIs
 Android 2.3.3 - Security Enhancements
 Android 3.0 - Bluetooth Profiles
 Android 4.0 - Bluetooth Health Device Profile

5.  The following tools were used
 Arduino Mega ADK Board
 Arduino Bluetooth Shield
 Asus Eee Pad
 Eclilpse, Android SDK, Arduino IDE

8.  Hello World

9.  Traffic Lights
 Press Buttons on
Android
 Toggle LEDs

10.  Android code in Eclipse
 Arduino sketch in Arduino IDE
 Put it all together
 Demo app

11.  Bluetooth API calls
 Enable Shield
 Pairing with device
 Connect to Bluetooth socket
 Communicate on Input and Output streams
 Send and Receive Messages
 Connection Management

12.  Bluetooth shield operates on serial interface.
 Enable shield commands

13.  Make sure the Arduino is paired with device

14.  Create and connect a BluetoothSocket
 Get Bluetooth Input and OutputStreams

15.  Communication is handled through streams

16.  Once connection has been established,
sending and receiving messages is simple

17.  Connection Management

18.  Connection management is problematic
 Data coming from Bluetooth shield needs to be monitored for
connection status messages
 Messages mixed in with other data from the device
 Making a robust Bluetooth connection can involve a lot of
computational overhead.
 Arduino has no control over …
 Shutting the connection down
 Trying to (re)establish a new connection

19.  Android device and Arduino board connected
via Bluetooth
 Arduino connected to barcode scanner over
RS232
 Barcode scanned
 Info sent to the Android device
 Device searches google shops for item
 Upload info to eBay for sale

28.  Code is relatively simple
 Boards are problematic
 Bluetooth works over 10-20ft
 USB for closer work
 Future Plans
 Raspberry Pi (demo)
