What is your problem?

I need the BluetoothDescriptor Type according to QBluetoothUuid::DescriptorType. In particular, I need to know if the descriptor is of type ClientCharacteristicConfiguration. I found that my device descriptor has the descriptorUuid of 2902 which would fit what I need. Am I right that the descriptorUuid is equivalent to the type or is it just a coincidence that it has the right value? If it's the right value, why is it of type Guid instead of a simple hex or int?

yes you're right.

when you learn more about ble it might make more sense to you.

it's full value is 00002902-0000-1000-8000-00805f9b34fb

2902 is the ble short uuid, which is equivalent to the long one.

the Guid class prefers to print the short uuid, if possible. but handles both.
