Detailed Description

Representation of a characteristic descriptor discovered.

Characteristic descriptors can be seen as the metadata of the characteristic. They can contain things such as the unit of the characteristic value, extra permission informations or the Client Configuration state in regard to notification or indication.

The descriptors of a characterstic are discovered by a Characteristic Descriptor Discovery Procedure, which can be initiated by either ble::GattClient::discoverCharacteristicDescriptors() or DiscoveredCharacteristic::discoverDescriptors().

The discovery procedure returns the UUID of the descriptor (its type) and its handle.

Read and write of the descriptor value can be initiated by ble::GattClient::read and ble::GattClient::write.
