Systems and methods for concurrent device discovery
Systems and methods are provided for performing multiple operations associated with a peer-to-peer network in parallel by using two or more independent transceivers. When performing a device discovery protocol, one transceiver may operate in a listen state and another transceiver may operate in a search state, so that an exchange of discovery messages may occur with a peer, regardless of whether the peer is in the listen state or the search state. In another aspect, one transceiver may be used to perform a device discovery protocol, allowing the other transceiver to maintain a communications link without interruption.
