  • Methods and apparatus for use in facilitating Wi-Fi peer-to-peer (P2P) wireless networking
    Patent number: 8953490
    Abstract: A wireless communication device is configured to store a plurality of profiles associated with applications. Each profile includes at least a discovery mode property and a device type property. In response to an application being activated, the wireless device enables a discovery mode for performing discovery in accordance with the discovery mode property retrieved from a selected profile associated with the application. When one or more devices are available for discovery, the wireless device receives information from each device, filters the received information to provide filtered information associated with one or more devices having a device type that matches the device type property, and provides the filtered information to the application. The wireless device may then establish, in accordance with one or more properties retrieved from the selected profile, a Wi-Fi P2P wireless network connection with at least one of the devices.
