How to add multiple permissions and properties to a characteristic

问题

There is only one constructor for type BluetoothGattCharacteristic

BluetoothGattCharacteristic(UUID uuid, int properties, int permissions)

Does the constructor take exactly one property and one permission?

For example, I want a characteristic to be both readable and writable. Doesn't this means I need two sets of permission-property pairs?

PERMISSION_READ
PROPERTY_READ

and

PERMISSION_WRITE
PROPERTY_WRITE

But according to the constructor, I can only set one permission and property when I need two of each right? So how do I add multiple permissions and properties to a characteristic?
