Abstract

A system and method for multi-radio control unifies disparate radio technologies and communication protocols and abstracts them such that a user of a personal electronic device having a plurality of disparate radios is not required to know or understand the radio technology needed to connect to a remote wireless device or service. An intermediate layer receives requests from a user interface application, generates specific driver commands to each radio, and returns information received from each radio to the user interface application module. A user interface application module initiates a search for available remote wireless devices, provides the user with information regarding the available remote wireless devices, and establishes a connection to an available remote wireless device in response to a user selection. The user interface application module also presents notifications to the user, and also handles disconnect requests and security credential dialogs.
