Abstract: An electronic device is described. During operation, this electronic device activates a communication channel having a carrier frequency in a radio in an interface circuit to listen for an advertising frame of interest from another electronic device during a scan window having a predefined duration. If the advertising frame of interest is received from the other electronic device, the electronic device terminates the listening before the predefined duration has expired and, using the communication channel in the radio, transmits the connect request to the other electronic device to establish the connection with the other electronic device. In this way, the delay between discovery of the other electronic device and establishing the connection is reduced. In addition, the power consumed by the electronic device while scanning for the other electronic device and initiating the connection is reduced.

Abstract: A primary portable device can access a vehicle by transmitting an activation message including a vehicle access credential to the vehicle. The primary portable device can additionally enable a secondary portable device to access the vehicle by transmitting the vehicle access credential to the secondary portable device. The connections between the primary portable device, secondary portable device, and vehicle can be based on a short-range wireless protocol, such as Bluetooth or Bluetooth LE.

Abstract: Time synchronization between a central wireless communication device and a peripheral wireless communication device is described. Events associated with an application are time stamped at the central wireless communication device, and one or more link layer messages are sent to the peripheral wireless communication device to provide time stamp information to replicate the event timing at the peripheral wireless communication device. A first link layer message includes information about an internal Bluetooth clock to calibrate a corresponding internal clock value at the peripheral wireless communication device. A second link layer message includes information about a current value for the Bluetooth clock and also a value for an offset that provides a time position at a finer granularity than the Bluetooth clock within a timeslot specified by the Bluetooth clock value. Application layer event synchronization between the central and peripheral wireless communication devices allow for power reduced dormant states between events.

Abstract: The described embodiments include a system for communicating between electronic devices. During operation, a receiving electronic device receives a data channel protocol data unit (PDU) in a link layer of a Bluetooth Low Energy (BTLE) protocol stack. The receiving electronic device then reads a field in a header of the data channel PDU to determine if the header indicates that a payload of the data channel PDU contains audio data. When the header indicates that the payload of the data channel PDU contains audio data, the receiving electronic device is configured to send the audio data from the payload to an audio layer in the BTLE protocol stack for processing.
