    1. Assisted Living Cham Oh December 5, 2005

    3. Medical Devices Criteria Wireless Technology Medical Features Pluggability Programmability Design Cost

    4. Nonin Pulse Oximeter Bluetooth (30 ft range) SpO2, heart rate, plethysmographic data Can be connected to any bluetooth-enabled device Open communication protocols Development kit support $495 www.nonin.com

    5. RFID Devices Long-range detection Tracking/locationing Programmability Design Cost

    6. RFID Products RFIDeas Xtag IAutomate

    7. RFID Issue Is it possible to exactly locate the tag?

    8. Cell Phone Programming Embedded Runtime Environments BREW (Binary Runtime Environment for Wireless) Developed by Qualcomm C/C++ J2ME (Java 2 Platform Micro Edition) Developed by Sun Java

    9. BREW vs. J2ME

    10. Cell Phone Programming Which cell phone do we need to purchase? Bluetooth J2ME SDK support Motorola Bluetooth-enabled J2ME support Motorola SDK v5.2.1 for J2ME Device emulator support

    11. J2ME Development J2ME IDE JDK 5.0 Update 6 NetBeans with Mobility Pack (http://www.netbeans.org/downloads/index.html) CodeWarrior Wireless Studio 7.0 (http://www.metrowerks.com) � pay toolkit Java APIs Bluetooth Wireless Technology (JABWT), JSR082 Network APIs

    12. Bluetooth Stack

    13. Bluetooth Application

    14. Initialization ... private LocalDevice localDevice; // local Bluetooth Manager private DiscoveryAgent discoveryAgent; // discovery agent ... /** * Initialize */ public void btInit() throws BluetoothStateException { localDevice = null; discoveryAgent = null; // Retrieve the local device to get to the Bluetooth Manager localDevice = LocalDevice.getLocalDevice(); // Servers set the discoverable mode to GIAC localDevice.setDiscoverable(DiscoveryAgent.GIAC); // Clients retrieve the discovery agent discoveryAgent = localDevice.getDiscoveryAgent(); } ...

    15. DiscoveryAgent / DiscoveryListener

    16. Device Discovery State

    17. Service Discovery State

    18. Discovering Nearby Dervices public class BtClient implements DiscoveryListener { ... Vector discoveredDevices = new Vector(); ... // DiscoveryListener Callbacks /////////////////////// /** * deviceDiscovered() is called by the DiscoveryAgent when * it discovers a device during an inquiry. */ public void deviceDiscovered( javax.bluetooth.RemoteDevice remoteDevice, javax.bluetooth.DeviceClass deviceClass) { // Keep track of discovered remote devices by inserting // them into a Vector ... } /** * inquiryCompleted() is called by the DiscoveryAgent when * a device discovery cycle finishes. */ public void inquiryCompleted(int param) { // Now that the inquiry has been completed, if any // devices were discovered trigger the search for services ... }

    19. Discovering Nearby Services /** * servicesDiscovered() is called by the DiscoveryAgent when * a service search finds services. * transID identifies the service search that returned results. * serviceRecord holds references to the services found. */ public void servicesDiscovered(int transID, javax.bluetooth.ServiceRecord[] serviceRecord) { // Keep track of discovered services, adding them // to a Vector ... } /** * serviceSearchCompleted() is called by the DiscoveryAgent * implementation when a service search finishes. * transID identifies a particular service search. * responseCode indicates why the service search ended. */ public void serviceSearchCompleted (int transID, int responseCode) { // Now that the service discovery has been completed, // dispatch thread to handle the discovered services ... }

    20. UUID Class Universally Unique Identifier required for each service Represents short (16 or 32-bit) and long (128-bit) UUIDs Use command uuidgen (Windows), or uuidgen �t (Linux) Ex) 2d266186-01fb-47c2-8d9f-10b8ec891363

    21. SDDB and ServiceRecord Class

    22. Device ManagementLocalDevice Class

    23. RemoteDevice Class

    24. Bluetooth Communication

    25. Network APIs CommConnection for serial interface HTTP connection HTTPS connection Socket Support UDP SSL

    26. Socket Connection

    27. Socket Connection
