此範例檔的藍芽連線，需事先在手機做好與藍芽裝置的配對，android再指定對方藍芽裝置的MAC位置進行連線。
*此範例是與mBot的藍芽裝置連線，若是藍芽裝置接麵包板可能要設定pin腳，不適用本範例，但可參考android藍芽連線。
Android部分
AndroidManifest.xml：
<uses-permission
android:name="android.permission.BLUETOOTH"
/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
建立一個類別檔叫AsClientConnectBT
public class AsClientConnectBT {
BluetoothAdapter mBtAdapter = BluetoothAdapter.getDefaultAdapter();
BluetoothSocket socket;
BluetoothDevice device;
InputStream inStream;
OutputStream outStream;
UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); //固定的字串
byte[] msgBuffer;
public AsClientConnectBT(){
device = mBtAdapter.getRemoteDevice("00:0D:19:03:17:D5"); //對方藍芽裝置MAC位置
try {
socket = device.createRfcommSocketToServiceRecord(MY_UUID);
inStream = socket.getInputStream(); //接收傳來的資料
outStream = socket.getOutputStream(); //傳送資料給arduino
} catch (IOException e) {
e.printStackTrace();
}
}
public void run(){
try {
socket.connect();
} catch (IOException e) {
e.printStackTrace();
}
}
public void cancel(){
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
public void SendMsg(){
try {
outStream = socket.getOutputStream();
} catch (IOException e) {
e.printStackTrace();
}
msgBuffer = "0".getBytes(); //傳送0
try {
outStream.write(msgBuffer);
} catch (IOException e) {
e.printStackTrace();
}
}
}
MainActivity檔案
public class MainActivity extends AppCompatActivity {
AsClientConnectBT clientCon = new AsClientConnectBT();
TextView tv;
Button btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView)findViewById(R.id.textview);
btn = (Button)findViewById(R.id.button);
btn.setOnClickListener(btnClick);
clientCon.run();
}
public Button.OnClickListener btnClick = new Button.OnClickListener(){
@Override
public void onClick(View v) {
clientCon.SendMsg();
}
};
}
