写一段安卓7.0的ble蓝牙的读写代码

以下是一段安卓7.0的BLE蓝牙读写代码，供参考：

// 初始化蓝牙适配器
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();

// 获取远程设备
BluetoothDevice device = bluetoothAdapter.getRemoteDevice(address);

// 连接远程设备
BluetoothGatt gatt = device.connectGatt(this, false, new BluetoothGattCallback() {
    // 连接状态改变回调
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            // 连接成功，开始发现服务
            gatt.discoverServices();
        } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            // 连接断开，释放资源
            gatt.close();
        }
    }

    // 发现服务回调
    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            // 获取服务
            BluetoothGattService service = gatt.getService(serviceUuid);

            // 获取特征值
            BluetoothGattCharacteristic characteristic = service.getCharacteristic(characteristicUuid);

            // 读取特征值
            gatt.readCharacteristic(characteristic);

            // 写入特征值
            byte[] data = new byte[]{0x01, 0x02, 0x03};
            characteristic.setValue(data);
            gatt.writeCharacteristic(characteristic);
        }
    }

    // 读取特征值回调
    @Override
    public void onCharacteristicRead(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            // 读取成功，获取数据
            byte[] data = characteristic.getValue();
        }
    }

    // 写入特征值回调
    @Override
    public void onCharacteristicWrite(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            // 写入成功
        }
    }
});
