Bons dias a todos,
estou actualmente a desenvolver uma pequena aplicação que requeres ligação Bluetooth entre uma placa de Bitalino (módulo Bluetooth de Arduino) e um Android, sendo que tenho usado o meu (Galaxy S3) para testes.
A aplicação funciona em todos aspectos excepto no principal. Não faz a ligação com entre os dois dispositivos, no entanto, emparelha-os.

O código completo:
public class MainActivity extends AppCompatActivity {
private Switch switchOne;
private ListView listView;
private ToggleButton toggleButton;
private ConnectThread connect;
private ArrayList<String> deviceList = new ArrayList<String>();
private BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
private UUID myUUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
switchOne = (Switch) findViewById(R.id.switch1);
listView = (ListView) findViewById(R.id.listView);
toggleButton = (ToggleButton) findViewById(R.id.toggleButton);
final Intent discoverability = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverability.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
final IntentFilter filter = new IntentFilter();
filter.addAction(BluetoothDevice.ACTION_FOUND);
registerReceiver(receiver, filter);
toggleButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
startActivity(discoverability);
adapter.startDiscovery();
filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
} else {
adapter.cancelDiscovery();
filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
}
}
});
switchOne.setOnCheckedChangeListener((new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
//startActivity(new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE));
adapter.enable();
} else {
adapter.disable();
}
}
}));
if (adapter.isEnabled()) {
switchOne.setChecked(true);
} else {
switchOne.setChecked(false);
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
adapter.cancelDiscovery();
final String info = ((TextView) arg1).getText().toString();
String address = info.substring(info.length() - 17);
BluetoothDevice selected = adapter.getRemoteDevice(address);
connect = new ConnectThread(selected);
connect.run();
}
});
}
private void showToast(String text) {
Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
}
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(action)) {
showToast("Discovery started");
deviceList = new ArrayList<String>();
toggleButton.setChecked(true);
} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
toggleButton.setChecked(false);
showToast("Discovery finished");
} else if (BluetoothDevice.ACTION_FOUND.equals(action)) {
//Found the BlueTooth device
BluetoothDevice device = (BluetoothDevice) intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
//Adds the devices to a list
deviceList.add(device.getName() + "\n" + device.getAddress());
Log.i("BT", device.getName() + "\n" + device.getAddress());
listView.setAdapter(new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, deviceList));
showToast("Found " + device.getName() + "\n" + device.getAddress());
}
}
};
private class ConnectThread extends Thread {
private BluetoothDevice bluetoothDevice;
private BluetoothSocket bluetoothSocket;
public ConnectThread(BluetoothDevice device) {
bluetoothDevice = device;
BluetoothSocket temp = null;
try {
temp = device.createRfcommSocketToServiceRecord(myUUID);
} catch (IOException e) {
showToast("Thread: Can't create socket");
}
bluetoothSocket = temp;
}
public void run() {
adapter.cancelDiscovery();
try {
bluetoothSocket.connect();
} catch (IOException e) {
showToast("Thread: Can't connect socket");
try {
bluetoothSocket.close();
} catch (IOException f) {
showToast("Thread: Can't close socket");
}
}
//Manage the connection here
}
public void cancel() {
try {
bluetoothSocket.close();
} catch (IOException e) {
showToast("Thread: Can't cancel");
}
}
}
}
A toast que aparece ao carregar no item: "Thread: Can't connect socket"
Que estou a fazer mal? Que me está a faltar?
