I want iOS device identifier for a framework that is used in multiple vendor's apps. I'm developing a framework to control a peripheral. The framework has to send unique information to register the device with the peripheral. My naive idea was to use IdentifierForVendor. But this API provides the device identifier for the same vendor's apps, not the framework. (The framework will be used by multiple vendors.) Is there a usable device identifier for the framework, regardless of app vendor? Please tell me any solution.

I have a BLE device and I'm developing an iOS app that communicates with that device. The device has a characteristic that has both notify and indicate properties, and sends some messages via notify and others via indicate, therefore I cannot use setNotifyValue. If the specified characteristic’s configuration allows both notifications and indications, calling this method enables notifications only. Is there any way to enable simultaneously both notify and indicate for the same characteristic?
