Embodiments described herein provide for a mobile electronic device including a wireless network interface coupled to a bus, a memory device coupled to the bus, and one or more processors coupled to the bus, the one or more processors to execute instructions to perform a scan, via the wireless network interface, for a beacon advertisement that is broadcast by a wireless device within range of the wireless network interface, detect the beacon advertisement broadcast by the wireless device, retrieve an identifier broadcast within the beacon advertisement, based on a result of a comparison between the identifier to at least one expected identifier, selectively send a timer reset packet to the wireless device and an authorization token for the wireless accessory to remain in near-owner mode, and allow the one or more processors to sleep for a predetermined time.

Non-waking maintenance of near owner state

Embodiments described herein provide for system and methods to crowdsource the location of wireless devices and accessories that lack a connection to a wide area network. One embodiment provides for a data processing system configured to perform operations comprising loading a user interface on an electronic device, the user interface to enable the determination of a location of a wireless accessory that is associated with the electronic device, generating a set of public keys included within a signal broadcast by the wireless accessory, the signal broadcast during a first period, sending the set of public keys to a server with a request to return data that corresponds with a public key in the set of public keys, decrypting the location data using a private key associated with the public key, and processing the location data to determine a probable location for the wireless accessory.

System and method for locating wireless accessories

Some aspects of this disclosure include apparatuses and methods for implementing a synchronized short range communication protocol scan mechanism across multiple devices. Some aspects relate to an electronic device including a transceiver configured to communicate based on a short range communication protocol and a processor communicatively coupled to the transceiver. The processor receives one or more parameters from a peripheral electronic device and determines, based at least on the one or more parameters, one or more synchronization parameters. The processor further transmits the one or more synchronization parameters to the peripheral electronic device. The one or more synchronization parameters can include at least a scan offset associated with the peripheral electronic device.

Distributed and synchronized bluetooth scan across multiple devices for faster bluetooth discovery

Methods to provide separation notifications are described. In an embodiment, movement is detected beyond a threshold distance from a trusted location, in response to the detecting, receiving an indication that at least one accessory device is nearby the electronic device and storing information on a status of a wireless connection with the at least one accessory device, receiving an indication that the electronic device is in transit, monitoring the wireless connection for the at least one accessory device, and upon detection of a lost wireless connection for the at least one accessory device, send a separation notification.

Separation alerts for notification while traveling

An example system includes an application processor (AP), a transceiver associated with a firmware layer and a controller. The controller is configured to perform operations that include receiving data representing a clock synchronization request from a remote device, such as a UWB clock synchronization request. The request is received by the transceiver over a wireless communication link. The controller generates a response to the synchronization request. The response is configured for synchronizing a remote clock of the remote device and a local clock of the mobile device. The controller sends, to the remote device by the transceiver, the response to the synchronization request.

Synchronization estimation based on ultra-wideband connections

Methods, systems, and apparatuses are presented to utilize Bluetooth (BT) radios to synchronize ultra wideband (UWB) radios, to allow the UWB radios to operate within narrow transmit/receive windows, which may lead to power savings. In some implementations, a transmitting UWB radio and a receiving UWB radio may synchronize the expected time of an UWB transmission based on BT events, such as receiving a BT advertisement, or establishing a BT connection. In some implementations, the transmitting UWB radio and the receiving UWB radio may synchronize the expected time of an UWB transmission based on synchronized event counters maintained by the BT radios. Information regarding UWB transmission start times may also be passed via BT communications, in some implementations.

Bluetooth&#x2014;ultra wideband synchronization

Embodiments disclosed herein relate to reducing a power consumption of an electronic device while maintaining some functionality of the electronic device while the electronic device is in a low power mode. The device may be in the low power mode due to a battery level being below a threshold. If the battery level is below the threshold, the electronic device may enter the low power mode. However, before entering the low power mode, some functionality of an application processor may be transferred to a communication controller. Once the functionality is transferred, the application processor may be disabled to reduce power consumption while maintaining functionality of the application processor. The electronic device may also utilize various communication protocols to communicate with a peripheral device. Even though the electronic device may be in the low power mode, the communication controller may be used to cause the peripheral device to perform various actions.

Electronic device functionality in low power mode

In some implementations, a computing device can calibrate media playback channels for presenting media content through a media system by determining the media propagation latency through the media system. For example, the computing device can send calibration content (e.g., audio data, video data, etc.) to various playback devices (e.g., playback channels) of the media system and record a timestamp indicating when the calibration content was sent. When the playback devices present the calibration content, a sensor device (e.g., remote control device, smartphone, etc.) can detect the presentation of the calibration content. The sensor device can send calibration data (e.g., media samples that may include the calibration content and/or a timestamp indicating when the media sample was detected by the sensor device) to the computing device. The computing device can determine the propagation latency (e.g., presentation delay) based on the calibration data received from the sensor device.

Calibrating media playback channels for synchronized presentation

An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface devices.
