    Abstract: A vehicle component may operate in a plurality of connectionless functional states including a watchdog state in which the component broadcasts advertisements indicating presence of the vehicle component to personal devices; a notify state in which the component broadcasts cycles of advertisements indicating available features of the component; and a process command state in which the component broadcasts current feature state advertisements responsive to command advertisements received from the personal devices. A personal device may operate in a plurality of connectionless functional states including an acquire interface state in which the personal device collects information indicative of component functions based on non-connectable advertisements from in-vehicle components; a display interface state in which the personal device provides a user interface of controls based on information collected during the acquire interface state; and a process command state in which the device broadcasts command advertisements responsive to operator input to the user interface.

    Abstract: A computer-implemented method includes receiving a request from a mobile device to activate a recognition sequence. The method also includes transmitting a plurality of time-stamped recognition codes to the device, responsive to the request. The method further includes receiving an acknowledgement following transmission of a proper recognition code. The method also includes calculating a time-delay between transmission of the proper recognition code and acknowledgement receipt. The method additionally includes receiving a key-code from the device and comparing the key-code to a code exchanged with the device when the device was previously present within a vehicle. Further, the method includes measuring the received strength of multiple wireless signals successively received from the device and conditional on the time-delay being below a predefined threshold, verification of the key-code and the received signal strength of multiple wireless signals matching a predefined pattern of increasing signal strength, providing vehicle system access to the device.
