Как отправить файл из приложения J2me с помощью bluetooth

Question

Я пытаюсь отправить файл из приложения j2me на все доступные устройства Bluetooth в диапазоне, близком к этому.

Я искал устройства в диапазоне и отображался, но не смог отправить файл на это устройство. Я получаю код ответа как 211, получая ответ в связи.

Я добавил мой код:

private void SendingFile() { 
    myForm.setTitle("Sending.."); 
    for (int k = 0; k < myForm.size(); k++) { 
     myForm.delete(k); 
    } 
    myForm.append("Sending application.."); 
    display.setCurrent(myForm); 
    try { 
     RemoteDevice remotedevice = (RemoteDevice) myVector.elementAt(devList.getSelectedIndex()); 
     dAgent.searchServices(null, new UUID[]{new UUID(0x1105)}, remotedevice, this); 
     return; 
    } catch (BluetoothStateException bluetoothstateexception1) { 
     myForm.append("could not open bluetooth: " + bluetoothstateexception1.toString()); 
    } 
} 

public void pauseApp() { 
} 

public void destroyApp(boolean flag) { 
} 

public void commandAction(Command command, Displayable displayable) { 
    if (command == cmdScan) { 
     if (myForm == null) { 
      myForm = new Form("Scanning"); 
     } else { 
      for (int i = 0; i < myForm.size(); i++) { 
       myForm.delete(i); 
      } 
     } 
     myForm.append("Scanning for bluetooth devices.."); 
     Display.getDisplay(this).setCurrent(myForm); 
     if (devList == null) { 
      devList = new List("Devices", 3); 
      devList.addCommand(cmdSend); 
      devList.setCommandListener(this); 
     } else { 
      for (int j = 0; j < devList.size(); j++) { 
       devList.delete(j); 
      } 
     } 
     if (myVector == null) { 
      myVector = new Vector(); 
     } else { 
      myVector.removeAllElements(); 
     } 
     try { 
      if (localDev == null) { 
       localDev = LocalDevice.getLocalDevice(); 
       localDev.setDiscoverable(DiscoveryAgent.GIAC); 
       dAgent = localDev.getDiscoveryAgent(); 
      }

убедитесь, что устройства все в пределах и поддерживать соединения и попробуйте ниже код

private void CheckDevice(int indexxx, int size) { 
    try { 
     for (int i = 0; i < size; i++) { 

      DeviceName = devList.getString(i).toString(); 
      remotedevice = (RemoteDevice) myVector.elementAt(i); 
      devAdds = remotedevice.getBluetoothAddress().toString(); 
      if ((!rmsObj.rmsData.contains(devAdds) && (!Failed_Devices.contains(devAdds)) && (!AllDevices.contains(devAdds)))) { 

       SSSendingFile(i); 
       return; 
      } 
     } 
    } catch (Exception e) { 
     SendingFailed(); 
    } 
} 

private void SSSendingFile(int seldeviceindex) { 
    myForm.setTitle("Bluetooth Devices Found"); 
    myForm.deleteAll(); 
    display.setCurrent(myForm); 

    LoadingScreen("Try to Pair with ".concat(DeviceName), "pairing"); 
    try { 
     AllDevices.addElement(devAdds); 
     dAgent.searchServices(null, new UUID[]{new UUID(0x1105)}, remotedevice, this); 
     return; 
    } catch (BluetoothStateException bluetoothstateexception1) { 
     myForm.append("Could Not Open Bluetooth: " + bluetoothstateexception1.toString()); 
     SendingFailed(); 
    } catch (Exception ex) { 
     Date_Purpose("Service Serach EXC:" + DeviceName + " :" + ex.getMessage()); 
     if (!Devices_Fail_Name.contains(DeviceName.toString()) && (!remotedevice.equals("")) && (remotedevice != null)) { 
      Devices_Fail_Name.addElement(DeviceName.toString()); 
     } 
     Failed_Devices.addElement(devAdds); 
     SendingFailed(); 
    } 
}
