Tizen Native Accessory Guide

Accessory Peer Agents (both Service Providers and Service Consumers) are expected to handle concurrent instances, which means it is possible for a Service Provider to accept incoming Service Connections from multiple Service Consumers of the same Accessory Service Profile (E.g. Notification Service) and vice versa. Every accepted Service Connection request will result in the creation of a Service Handle, which represents the dialogue between Service Provider and Service Consumer of the same Accessory Service Profile. Accessory Service Framework establishes one or more Service Channel(s) with the QoS parameters as necessitated by Accessory Service Profile.
