    <p>I have been stuck on this for days. I have come up with a code to send bytes of data to my Bluetooth module. I don't get any errors, but I am not sure that the data is actually being sent. I have used an oscilloscope to check the RX and TX pins on the module, but I get nothing. Anyone know what is wrong? Here is my code:</p> <pre><code>import java.io.IOException; import java.io.OutputStream; import java.util.Set; import java.util.UUID; import android.app.Activity; import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import android.bluetooth.BluetoothSocket; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; public class Modes extends Activity { Button gaming; Button graphics; Button sound; Button text; BluetoothDevice mmDevice; BluetoothSocket mmSocket; OutputStream mmOutputStream; BluetoothAdapter mBluetoothAdapter; byte val; private final UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.modes); setUp(); gaming.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { System.out.println("gkghfgh"); val = 0; try{ connect(); senData(); }catch(IOException ex){} } }); graphics.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { val = 1; try{ connect(); senData(); }catch(IOException ex){} } }); sound.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { val = 8; try{ connect(); senData(); }catch(IOException ex){} } }); text.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { val = 9; try{ connect(); senData(); }catch(IOException ex){} startActivity(new Intent(Modes.this,Text.class)); } }); } private void setUp() { gaming = (Button) findViewById(R.id.button1); graphics = (Button) findViewById(R.id.button2); sound = (Button) findViewById(R.id.button3); text = (Button) findViewById(R.id.button4); gaming.setText("Gaming"); graphics.setText("Graphics"); sound.setText("Sound"); text.setText("Text"); } void connect() throws IOException{ mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); Set&lt;BluetoothDevice&gt; pairedDevices = mBluetoothAdapter.getBondedDevices(); if(pairedDevices.size() &gt; 0) { for(BluetoothDevice device : pairedDevices) { if(device.getName().equals("RN42-58C1")) { mmDevice = device; break; } } } mmSocket = mmDevice.createRfcommSocketToServiceRecord(uuid); mmSocket.connect(); } void senData() throws IOException{ mmOutputStream.write(val); System.out.println("Data Sent"); } } </code></pre>

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.
