Bluetooth DeviceClass does not work on 8703e

I don't get the major and minor device on an 8703e class. No idea why?

Here is the result of the code below run on 3 different phone:

The first 3 found device are other phone around the Office (I don't like for those). The 4th is the one that I am interested in (it's our device based on an Azuro Bluetooth OEM module).

Here is the code:

package pascal;

import net.rim.device.api.ui.UiApplication;

public class BTDeviceClass extends UiApplication {  public static BTDeviceClass app;

  public static void main(String[] args) {      try {         app = new BTDeviceClass();            app.pushScreen(BTDeviceClassScreen.getInstance());            app.enterEventDispatcher();       } catch (Throwable t) {           t.printStackTrace();      } }}

package pascal;

  public static BTDeviceClassScreen getInstance() throws BluetoothStateException {      BTDeviceClassScreen instance = new BTDeviceClassScreen();     instance.initUI();        instance.agent = LocalDevice.getLocalDevice().getDiscoveryAgent();        return instance;  }

   void doSearchMenu() throws BluetoothStateException {      sbuf.setLength(0);        agent.startInquiry(DiscoveryAgent.GIAC, this);    }

  protected void makeMenu(Menu menu, int instance) {        menu.add(getSearchMenu());    }

   private MenuItem getSearchMenu() {        if (searchMenu==null) {           searchMenu = new MenuItem("Search", 1, 10) {              public void run() {                   try {                     doSearchMenu();                   } catch (BluetoothStateException e) {                     e.printStackTrace();                      appendLine(e.toString());                 }             }         };        }     return searchMenu;    }

   public void deviceDiscovered(RemoteDevice device, DeviceClass deviceClass) {        appendLine("Found: " + device.getBluetoothAddress()                 + ", Major:" + Integer.toHexString(deviceClass.getMajorDeviceClass())                + ", Minor:" + Integer.toHexString(deviceClass.getMinorDeviceClass()));    }

   public void inquiryCompleted(int discType) {      appendLine("Search Completed: " + discType);  }

   public void servicesDiscovered(int transID, ServiceRecord[] servRecord) { }

   public void serviceSearchCompleted(int transID, int respCode) {   }}

Have you tried matching first your device?  I ran into a problem where the device class numbers are zero if the device is not paired.  This has been confirmed by RIM as a bug in 4.2.1

I had to work around this problem, implement the logic that checks the friendly name as a return to the top.

  • Bluetooth headset does not work with Windows 7 - device is detected.

    I have a Dell XPS 1530, which had Vista 32 bit running. I have recently upgraded to Windows 7 Ultimate. Ever after that the Bluetooth of DELL BH 200 headset does not work with my laptop.

    The bluetooth adapter and the device is fine since I'm able to search and find all bluetooth devices, including my helmet. However, I get a yellow exclamation on the headset under devices. The headset can be paired with other devices such as my mobile and works very well.

    I tried to update the drivers and reinstall the device and the adapter from the Device Manager. We have a similar setup on my brother's computer and it works fine.

    Another thing to watch, would be what battery is used.  I know from personal exp some devices work with Toshiba stack, vs the MSFT pile up.  Do a search and see if anyone else uses a different battery with these devices.

  • Bluetooth mouse does not work up to this that deleted and added after Windows startup

    After you have added a device, namely my mouse Logitech V470 Bluetooth, it works fine until I turned off my laptop.

    The next day when I have power to the top of the mouse is no longer my Dell Vostro 1500, moves the cursor. But it is still displayed in the list of devices.

    The only way I can get it to again control must "remove hardware". Then I 'add device', it is discovered, and the driver is loaded.

    What can I do to have the mouse early control after turning on the laptop?

  • my bluetooth application does not work

    I would like to ask how to run my application bluetooth in my acer netbook.  I had been through the msg will appear on the screen saying RUN... but still does not work. I wanted to send music from my phone to my netbook but its not working... pls hepl me I do not know how to handle fixing it... Thank you and looking forward to hear from you.

    Hello

    Thanks for posting the request in the Microsoft community!

    I imagine the inconvenience that you are experiencing. I will certainly help the question of fixing.

    1. what happens when you try to send music from a mobile phone?
    2. you receive an error message?

    Method 1:
    To do this, you must control how pairs with the computer (which connects to) Bluetooth devices. To control how your computer pairs with Bluetooth devices

    a. open Control Panel by clicking the Start button, then Control Panel.

    b. in the search panel box command, type Bluetooth, and then click change Bluetooth settings.

    (c) in the Bluetooth settings dialog box, click the Options tab and do one of the following:

    · Pour rendre make your computer discoverable to Bluetooth devices, select the check box for Allow Bluetooth devices to find this computer.

    When a computer active Bluetooth device is in discoverable mode, it broadcasts a wireless signal that allows it to be detected by other Bluetooth compatible computers or devices. This is sometimes called pairing mode.

    · To allow Bluetooth devices to connect to your computer, select the check box for Allow Bluetooth to connect to this computer devices.

    · To be notified when a Bluetooth device is trying to connect to your computer, check the box for warn me when a new Bluetooth device wants to connect.

    See the link to add the Bluetooth on the computer.

    Good day it

    I've had one laptop to another in the past and I didn't have this problem with this computer, but then 3 weeks ago I bought myself this Qosmio F20 and try to send the info to my Sony-Ericsson K600i.
    He worked with my other laptop. On my laptop I don't see devices in the Control Panel, but it doesn't seem to be any information for any active or visible Bluetooth to my phone.

    Could you help me please or tell me where to get the program?

    Concerning

    Hello

    It would be very useful to know the name of your unit. Qosmio F20 - xxx.
    I ask because the Bluetooth module is not available on several units of Qosmio F20.
    In my opinion you should first check if the laptop supports Bluetooth.
