I'm wondering if there's any way to set the BLE GATT Report Reference descriptor in iOS.
https://developer.apple.com/documentation/corebluetooth/cbmutabledescriptor
According to the document, Apple only supports 2 descriptors among all 15 types in the spec.

This limits the possibility of creating many essential Bluetooth applications.
