Sample of BluetoothDemo - BtSppWrite was not

Hello
I use Blackberry bold 9000, os 5 and I have problems to run sample BluetoothDemo, in particular I have problems making both devices associated to communicate.
I changed the constructor of the AppScreen class, because he was not able to find any device which port has ' Hi there ' as name of service, so I have:

/ public final class AppScreen extends screen
{
private BluetoothSerialPortInfo [_portInfo];
   
/**
* Default constructor
*/
public AppScreen()
{
setTitle ("Bluetooth sample");

Determine if this model of BlackBerry or the Simulator supports Bluetooth
If (BluetoothSerialPort.isSupported ())
{
Download the BluetoothSerialPortInfo.  Retrieves serial port information for
the currently connected devices.
_portInfo = BluetoothSerialPort.getSerialPortInfo ();
int numServices = _portInfo.length;

Create a MenuItem for each Bluetooth device to connect.
for (int count = numServices - 1; count > = 0;--comte))
{
String serviceName = _portInfo [count] .getServiceName ();
               
A single device can provide several serial port connections (or services).
Add a menu only item to the service that corresponds to the connection "Hi there."
or the connection "COM X" (if we are attached to a computer).
If (serviceName.equals ("Hi there"): serviceName.equals ("COM X"))
{
DeviceMenuItem deviceMenuItem = new DeviceMenuItem ("connect to:" + _portInfo [count] .getDeviceName (), _portInfo [count]);
addMenuItem (deviceMenuItem);
}
}

addMenuItem (_listenItem);
}
on the other
{
Add (new LabelField ("Bluetooth is not supported on this device."));
}
}

now, he is able to find two services, service desk and Bypass, on both devices.
Then on device 'A', I select 'listen to connections', the 'B' device I select "connect A device" (there are two menu items, a service bureau and the other for the circumvention service, I guess).
When I accept the connection of one of the two services request, I have is «connection to the computer...» «or the screen still says "connect the external device and then type something...» "on A device.
If I try to write something on the Unit B (client), it does not appear on the device (server), but it does not launch any which exception, while if I try to write something on the server, I "cannot write data: java.io.IOException: BtSppWrite failed.
I don't know where is the problem, especially because it worked twice, and then I've never been able to do more work.

This solves the problem:

  • error "Ibsta" no was not declared in this scope

    I have a "error: 'Ibsta' was not declared in this scope."

    I try to program with C++ and GPIB test equipments, but so far, I have this problem.

    I'm sorry, but my knowledge of C++ is very limited because I took a module on it for about 4 months in College and now I have to rectify emergency for my project. Any help would be much apprciated, I tried searching the forums, but I still have to find an answer. I think it has something to do with my linker.

  • Converter Standalone 4.3.0 question - Get "the specified parameter was not correct" and no source listed volumes

    Sorry - hopefully an admin can move this to the correct forum. I could find no community forum labeled converter so no idea where to post this message.

    My first time trying to use the converter. Use the latest version of the Converter 4.3.0 to try a P2V by using the source computer. This is a laptop Dell D820 running Windows 7 Ultimate x 64 business. I chose the source machine and all the default settings. Destination product is VMware Workstation 7.x and target files are either local or to a port USB drive (tried both). In the last step, I get a yellow bar with the error "the specified parameter was not correct" "but the following quotes are empty and presume it suppose to say the name of the setting.» The only thing I see that is suspect is that if I click on change in section 'Data copy', the list of volumes and empty and assume that shouldn't be. The sample video to get advice on the use of converter on VMware support sites show a volume listed here. I tried the same approach on a completely different system under Vista SP2 and still no volumes appear so maybe it normal?

    No idea what I am doing wrong? I did export logs and watch and it appears no volume information has been captured (a lot of & lt; destroyed & gt ;) but even once, just guessing.) Any advice would be appreciated greadly.

    Thank you

    Don

    I had the same problem on a Win7 x 64 machine... There was no listed disk to convert.

    I managed to solve the problem by running the converter as an administrator. Right-click on the Desktop Converter icon and select run as administrator.

    The disks appears and you can select which can be the converter.

  • 1046: type was not found or is not a constant of compilation: URLRequest.

    Hi all!

    I'm having a little difficulty with ActionScript 3 and I was wondering if someone could help me.

    I'm new to Flash CS5 and AS3, but I tried to create a sample track (originally single) application that allows the user to click on an image to start/stop an mp3, I had the initial sorting script where the button could toggle to go and stop the mp3. I tried hard for weeks, but as soon as I tried to package (to allow additions future script effects) he threw it to the top of the following error:

    C:\Users\Alice\Desktop\Prototype\com\app\Application.as, line 57

    1046: type was not found or is not a constant of compilation: URLRequest.

    Here is the code for the Application.as package

    package com.app {}



    to import flash.display.SimpleButton;

    import flash.media.Sound;

    import flash.media.SoundChannel;

    import flash.events.Event;

    import flash.display.MovieClip;

    import flash.events.MouseEvent;

    import flash.display.Sprite;

    import flash.net.URLLoader;


    SerializableAttribute public class Application extends MovieClip {}



    public var flag: Boolean;


    public void Application()

    {

    bozeat.addEventListener (MouseEvent.CLICK, bozeat_button_Handler);

    flag = false;

    }



    public void bozeat_button_Handler (e:MouseEvent): void {}


    bozeat_snd.load (new URLRequest ("drums.mp3"));

    if (flag == false) {}

    bzChannel = bozeat_snd.play (0, int.) MAX_VALUE);

    flag = true;

    trace ("true");

    { } else if(flag == true) {}

    bzChannel.stop ();

    flag = false;

    trace ("false");

    }

    }


    This is the error #1046: he keeps pointing me:

    bozeat_snd. Load (new URLRequest ("drums.mp3"));

    And here is the code for the .fla file

    import com.app.Application;

    App: var app = new Application();

    I named the document class for

    com.app.Application

    My mp3 is

    with an instance name of bozeat_sound drums.mp3

    I hope someone understands what I'm talking about lol. Sorry for the hassle for any help in advance thanks

  • Upgrade Windows 7 to Windows 10 and Thunderbird will not work. SOLVED was not logged as an administrator

    On my laptop, conversion of Windows 8 to 10 was fine and Thunderbird has worked without any problems. On the computer of my wife who was on Windows 7, Thunderbird does not work. Thanks to this forum I could check that all emails and addresses etc. have been copied across, but Thunderbird asks me to put in place the new account because it does not acknowledge my previous POP and other parameters. Bloody Microsoft. Can anyone help?

    I have found the answer - default (why?) I was connected as administrator and therefore was not seeking the e-mail account of my wife in the same way as it would. The search in all the files and directories of profile TB, I found a test directory, where TB was given to me. Do not know what other tricks that I solved the problem, but it is all working now. And people spend their entire lives on such things?

    Why has been upgraded to El Capitan failed before?

    The only problem is that some applications require the upgrade and some devices that connect to the computer require updated drivers up-to-date. The problem is that for some devices and applications updates are not available and so they do not work with El Capitan.
