【App】蓝牙Bluetooth，app的编写总结

蓝牙四大必须任务：1.设置蓝牙2.查找局部区域内的配对设备，或可用设备3.连接设备4.再设备之间传输数据蓝牙权限：BLUETOOTH,ACCESS_FINE_LOCATION		//android 9, API 28ACCESS_COARSE_LOCATION		// < android9借助远程设备的已知 MAC 地址，您可以随时向其发起连接，而无需执行发现操作	

是先看了别人写的测试apk，蓝牙wifi测试这些，然后发现别人写的思路完全就是套路。哈哈。程序基本步骤就是google开发者这个网站上写的。https://developer.android.google.cn/guide/topics/connectivity/bluetooth然后自己也敲了一遍代码，然后提取一些记录一下。步骤：

 /***********************************        开启蓝牙的两种方式** *********************************/1.if (!mBluetoothAdapter.isEnabled()) {mBluetoothAdapter.enable();}2. Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);

         /***********************************        step 1, 开启蓝牙，获得适配器** *********************************/BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();if (bluetoothAdapter == null) {Log.d("QYC",  "Device doesn't support Bluetooth");}if (!bluetoothAdapter.isEnabled()) {Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);startActivity(enableBtIntent);}/***********************************        step2，检查已连接过的设备** *********************************/Set pairedDevices = bluetoothAdapter.getBondedDevices();if (pairedDevices.size() > 0) {// There are paired devices. Get the name and address of each paired device.for (BluetoothDevice device : pairedDevices) {String deviceName = device.getName();String deviceHardwareAddress = device.getAddress(); // MAC addressLog.d("QYC", "qyc1, deviceName == " + deviceName);Log.d("QYC", "qyc1, deviceHardwareAddress == " + deviceHardwareAddress);}}/***********************************        step3，注册广播接收者，发现新设备** *********************************/IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);registerReceiver(receiver, filter);if (bluetoothAdapter.isDiscovering()) {bluetoothAdapter.cancelDiscovery();}bluetoothAdapter.startDiscovery();}//end onCreateprivate final BroadcastReceiver receiver = new BroadcastReceiver() {public void onReceive(Context context, Intent intent) {String action = intent.getAction();Log.d("QYC", "qyc, action == " + action);if (BluetoothDevice.ACTION_FOUND.equals(action)) {// Discovery has found a device. Get the BluetoothDevice// object and its info from the Intent.BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);String deviceName = device.getName();String deviceHardwareAddress = device.getAddress(); // MAC addressLog.d("QYC", "qyc, deviceName == " + deviceName);Log.d("QYC", "qyc, deviceHardwareAddress == " + deviceHardwareAddress);}}};
