Some interfaces support multiple Bluetooth adapters with events like add/remove. We must support that to distinquish adapters streams in case that new adapter has the same id that old one. Next one is create session for "Connection Handle", so next layer will now when it is connected and disconnected. This is also used to distinguish streams.
