摘要

The presence of a wireless device and/or accessory that cannot maintain an independent network connection can be detected by network connected wireless devices and the location of the detected device and/or accessory can be reported to a device location service. As the wireless devices and/or accessories do not have independent network connections, periodic maintenance is performed on those devices by nearby owner devices to which the wireless devices and/or accessories are paired or associated. Described herein are systems, methods, and associated devices to maintain a locatable wireless device by a set of multiple owner devices for that wireless device.

說明書

Various solutions can be applied to prevent the wireless accessory 201 from broadcasting in wild mode 840, or reduce the duration in which the wireless accessory 201 is in wild mode. In one embodiment, if either of mobile device 102A or mobile device 102B detect a wild mode packet that is matched to wireless accessory 201, the device can immediately connect to the wireless accessory 201 to place it back into near owner mode. In one embodiment, near owner timeouts and opportunistic timer settings can be adjusted to reduce the likelihood of a double timer event during the same key rotation period.

FIG. 9A-9B illustrate status and connection timing diagrams for multiple owner devices and a wireless accessory, according to an additional embodiment. In one embodiment, a near owner timeout of 20 minutes is used, along with 18 minute opportunistic timers. This timer configuration significantly reduces the likelihood of two maintenance timer firings within a single 15 minute key rotation period. Furthermore, if an entire key rotation period is missed, a timer is likely to fire before the wireless accessory 201 transitions into wild mode.
