Abstract: A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.

Abstract: Aspects of a method and system for half duplex audio in a Bluetooth stereo headset are provided. A service type and/or service activity levels may be detected over a link in a duplex communication system. The link may be dynamically changed according to the detected service activity levels in both direction of the link. The duplex communication system may be a communication system capable of supporting duplex communication, for example, a Bluetooth system, a 3GPP system, a WiMAX system, or a WiFi system. The link may be a synchronous connection-oriented (SCO) link such as the SCO link. The duplex communication system may be enabled to determine an operating mode, whether symmetric or asymmetric, based on the detected service type and/or the detected service activity levels over the SCO link. In this regard, the SCO link may be dynamically switched from symmetric to asymmetric operating mode and vice versa.
