    <p>I have used the below code to detect the active bluetooth devices and create a list of them. Once the active bluetooth device list is prepared we can select one device from list and send connection request to that device. Once the requested device accept connection request i need to get continuous incomming data signal from paired device.</p> <pre><code>protected void connect(BluetoothDevice device) { try { Log.d(TAG,"connect bluetooth"); // Create a Socket connection: need the server's UUID number of // registered Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class }); socket = (BluetoothSocket) m.invoke(device, 1); socket.connect(); Log.d(TAG, "&gt;&gt;Client connectted"); inputStream = socket.getInputStream(); socket.getOutputStream(); int read = -1; final byte[] bytes = new byte[2048]; while (true) { synchronized (obj1) { read = inputStream.read(bytes); Log.d(TAG, "read:" + read); if (read &gt; 0) { final int count = read; String str = SamplesUtils.byteToHex(bytes, count); // Log.d(TAG, "test1:" + str); String hex = hexString.toString(); if (hex == "") { hexString.append("&lt;--"); } else { if (hex.lastIndexOf("&lt;--") &lt; hex.lastIndexOf("--&gt;")) { hexString.append("\n&lt;--"); } } hexString.append(str); hex = hexString.toString(); // Log.d(TAG, "test2:" + hex); if (hex.length() &gt; maxlength) { try { hex = hex.substring(hex.length() - maxlength, hex.length()); hex = hex.substring(hex.indexOf(" ")); hex = "&lt;--" + hex; hexString = new StringBuffer(); hexString.append(hex); } catch (Exception e) { e.printStackTrace(); Log.e(TAG, "e", e); } } _handler.post(new Runnable() { public void run() { } }); } } } } catch (Exception e) { Log.e(TAG, "&gt;&gt;", e); Toast.makeText(getBaseContext(), getResources().getString(R.string.ioexception), Toast.LENGTH_SHORT).show(); return; } finally { if (socket != null) { try { Log.d(TAG, "&gt;&gt;Client Socket Close"); socket.close(); socket = null; // this.finish(); return; } catch (IOException e) { Log.e(TAG, "&gt;&gt;", e); } } } } </code></pre> <p>I need to detect continuous incomming data signals.Is it possible to do it. </p>

    2. COHi use this code to get device address from list of devices: result = new Intent(ACTION_PAIRING_REQUEST); result.putExtra(BluetoothDevice.EXTRA_DEVICE, _devices.get(devicePosition)); result.putExtra(EXTRA_PAIRING_VARIANT, EXTRA_PAIRING_VARIANT); BluetoothDevice finalDevice = result.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); where _device is the object like List<BluetoothDevice> _device=new ArrayList<BluetoothDevice>()

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
