Abstract: An audio output device may join an existing session between a source device and another audio output device. The source device may transmit audio data associated with an audio session, using a first frequency band, to a first wireless audio output device and transmit connection information associated with the audio session to a second wireless audio output device over a second frequency band. The second frequency band differs from the first frequency band and the connection information allows the second wireless audio output device to join the audio session. After transmitting the connection information, the source device may transmit subsequent audio data associated with the audio session to the first wireless audio output device and the second wireless audio output device.

Abstract: A method performed by a programmed processor of an in-ear headphone that is to be worn by a user. The method obtains, over a wireless communication link and via a first wireless connection that uses an accessory profile, a first request, from an audio source device, to start a measurement process. In response to obtaining the request, the method 1) establishes, over the link, a second wireless connection that uses an audio distribution profile between the headphone and the source device, 2) obtains, via the second wireless connection, an audio signal for driving a speaker of the headphone to output sound, 3) responsive to the outputted sound, determining a fit parameter, and 4) transmitting the fit parameter to the source device via the first wireless connection.

Abstract: 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.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

Abstract: A first device is configured to establish a connection over a short-range communication link with a second device. The first device may transition to a sleep state, terminate (i) a paging operation and a page scanning operation associated with a paging protocol and (ii) an advertisement scanning operation associated with an advertisement protocol and perform an advertisement broadcast operation associated with the advertisement protocol, the advertisement broadcast operation generating an advertisement to be broadcast at a first interval, wherein the first interval is greater than a second interval for performing advertisement broadcast operations in an active state.

Abstract: Methods for aggregating Bluetooth profiles for faster connection and configuration are disclosed, including transmitting, subsequent to establishing a connection, a request message to a peer device that indicates support of a fast connection protocol for Bluetooth profiles configuration and receiving a response message from the peer device that indicates the peer device supports the fast connection protocol. After pairing with the peer device, a first list of profile descriptors for a plurality of Bluetooth profiles supported by the device may be transmitted to the peer device and a second list of profile descriptors for a plurality of Bluetooth profiles supported by the peer device may be received. A configuration of a plurality of Bluetooth profiles base, at least in part, on a comparison of the first list of profile descriptors to the second list of profile descriptors may be determined and transmitted to the peer device.

Abstract: This document describes techniques for detecting and providing user notification of mismatched devices. A device mismatch of a pair of wireless devices may be detected. A wireless indication of the device mismatch may be provided to another wireless device. That wireless device may provide a user notification that the pair of wireless devices are mismatched.

Abstract: A first wireless communication device (UE device) associated with a certain user (or included in a specified set/group of UE devices) may establish a first communication link with an accessory device according to a short-range radio access technology, and transmit link (pairing) information associated with the first communication link to a server, such as a cloud-based server. The server may share this (first) link information with other UE devices associated with the same user (or belonging to the same specified group of UE devices as the first UE device). Link information associated with the other UE devices (i.e. second link information) may equally be shared with the accessory device, and the other UE devices and accessory device may use the first link information and second link information in establishing respective communication links between any of the other UE devices and the accessory device without having to undergo a pairing procedure.

Abstract: 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.
