该应用程序将自动连接到具有已知设备ID的BT连接。与配对设备的连接成功，但是当我尝试发送数据时，它会崩溃。
这是监听配对设备的BroadcastReceiver（需要工作但是有效）才能建立连接。
receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
devices.add(device);
for (int a = 0; a < pairedDevices.size(); a++) {
if (device.getName().equals(pairedDevices.get(a))) {
// append
Log.i("TAG", "IS Paired " + pairedDevices.get(a));
// s = "(Paired)";
isBTConnected = true;
if (btAdapter.isDiscovering()) {
btAdapter.cancelDiscovery();
}
BluetoothDevice selectedDevice = devices.get(0);
ConnectThread connect = new ConnectThread(selectedDevice);
connect.start();
break;
}
}
} else if (BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(action)) {
Log.i("TAG", "ACTION_DISCOVERY_STARTED");
} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
Log.i("TAG", "ACTION_DISCOVERY_FINISHED");
if (isBTConnected == false) {
Log.i("TAG", "Unable to connect");
} else {
Log.i("TAG", "Connected");
}
} else if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(action)) {
Log.i("TAG", "ACTION_STATE_CHANGED");
if (btAdapter.getState() == btAdapter.STATE_OFF) {
Log.i("TAG", "Disconnected ");
// turnOnBT();
}
}
}
};
这是ConnectThread创建套接字并将消息发送到主UI以启动。
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
BluetoothSocket tmp = null;
mmDevice = device;
Log.d("TAG", "construct");
// Get a BluetoothSocket to connect with the given BluetoothDevice
try {
tmp = device.createRfcommSocketToServiceRecord(MY_UUID); // MY_UUID is the app's UUID string, also used by the server code
} catch (IOException e) {
Log.i("TAG", "get socket failed");
}
mmSocket = tmp;
}
public void run() {
// Cancel discovery because it will slow down the connection
btAdapter.cancelDiscovery();
Log.i("TAG", "connect - run");
try {
// Connect the device through the socket. This will block
// until it succeeds or throws an exception
mmSocket.connect();
Log.i("TAG", "connect - succeeded");
} catch (IOException connectException) {
Log.i("TAG", "connect failed");
// Unable to connect; close the socket and get out
try {
mmSocket.close();
} catch (IOException closeException) {
}
return;
}
// Do work to manage the connection (in a separate thread)
mHandler.obtainMessage(SUCCESS_CONNECT, mmSocket).sendToTarget();
}
}
这是Handler收到开始收听的成功消息
mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
Log.i("TAG", "in handler");
super.handleMessage(msg);
switch (msg.what) {
case SUCCESS_CONNECT:
ConnectedThread connectedThread = new ConnectedThread((BluetoothSocket) msg.obj);
Toast.makeText(getApplicationContext(), "CONNECT", Toast.LENGTH_SHORT).show();
// String s = "successfully connected";
// connectedThread.write(s.getBytes());
Log.i("TAG", "connected");
break;
case MESSAGE_READ:
byte[] readBuf = (byte[]) msg.obj;
String string = new String(readBuf);
Toast.makeText(getApplicationContext(), string, Toast.LENGTH_SHORT).show();
break;
}
}
};
这是崩溃的踢球者。建立连接并创建套接字，这样我就会陷入困境。
mmOutputStream.write(buffer);是崩溃
发生错误的方法
private void SendPacket(int FixtureNumber, int R_value, int G_value, int B_value) {
byte buffer[] = new byte[7];
buffer[0] = ((byte) FixtureNumber);
buffer[1] = ((byte) ProcessDimmer(R_value, Master_value));
buffer[2] = ((byte) ProcessDimmer(G_value, Master_value));
buffer[3] = ((byte) ProcessDimmer(B_value, Master_value));
buffer[4] = ((byte) Tx_Control_Byte);
buffer[5] = ((byte) Tx_Control_Byte_0);
buffer[6] = ((byte) 254);
if (isBTConnected == true) {
try {
mmOutputStream.write(buffer);
} catch (IOException e) {
e.printStackTrace();
}
}
}

更多测试结果。我注释掉了输出流并测试了连接。
private void SendPacket(int FixtureNumber, int R_value, int G_value, int B_value) {
byte buffer[] = new byte[7];
buffer[0] = ((byte) FixtureNumber);
buffer[1] = ((byte) ProcessDimmer(R_value, Master_value));
buffer[2] = ((byte) ProcessDimmer(G_value, Master_value));
buffer[3] = ((byte) ProcessDimmer(B_value, Master_value));
buffer[4] = ((byte) Tx_Control_Byte);
buffer[5] = ((byte) Tx_Control_Byte_0);
buffer[6] = ((byte) 254);
Log.d("TAG", " Test " + isBTConnected + " Socket " + mmSocket + " Device " + mmDevice);
// if (isBTConnected == true) {
//
// try {
//
// mmOutputStream.write(buffer);
// } catch (IOException e) {
//
// e.printStackTrace();
// }
//
// }
}
以下是该测试方法的日志

SendPacket()来自Fragment listener。所有代码都正常运行
case 1: {
if (Fixture_Active_ColorRoll[FixtureNumber] == false) {
// RGB Value
// Log.d("TAG", "Scene Data " + Scene_ColorRoll_Option + " " + FixtureNumber);
intArrayRed[0] = R_value;
intArrayGreen[0] = G_value;
intArrayBlue[0] = B_value;
SetColorDot(0, R_value, G_value, B_value);
SendPacket(FixtureNumber, R_value, G_value, B_value);
