Abstract: Systems, methods, and non-transitory computer-readable storage media for performing a role swapping operation between a pair of non-tethered wireless ear buds after detecting a triggering event. Further, state information can be coordinated between devices, including in connection with performing a role swap between buds in a pair of wireless, untethered ear buds, where one wireless ear bud is in a primary role and is responsible for a connection with a companion device, and another wireless ear bud in the pair is in a secondary role.

Abstract: Embodiments of the present disclosure provide systems, methods, and computer-readable medium for pairing two proximate devices. An advertisement message associated with an accessory device may be received by a host device (e.g., a smart phone). The advertisement message may be communicated using a Bluetooth protocol (e.g., BLE). Payload data may be extracted from the advertisement message and utilized to obtain a media asset (e.g., an image, a video, an icon, etc.) associated with the accessory device. The media asset may be presented via a user interface at the host device. Input may be received indicating a request and/or an approval to perform a pairing procedure with the accessory device. In accordance with the input, the host device may execute the pairing procedure with the accessory device.

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.

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: The exemplary embodiments relate to implementing techniques for transmission of audio data from both of a pair of audio output devices to a user equipment (UE). A first wireless audio output device establishes a communication link to a source device using a wireless communication protocol, receives source audio data from the source device, receives secondary audio data from a second wireless audio output device and combines primary audio data from the first wireless audio output device with the secondary audio data into a consolidated audio packet. The consolidated packet is then transmitted to the source device.

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 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: A client device can be configured to identify data to be communicated with a network. In some examples, the client device can determine one or more transient properties of the client device and/or receive a connection request from a host device that is connected to the network, where the connection request comprises one or more connection properties of the host device. In some instances, the client device can also be configured to determine whether the host device is capable of transmitting the data to the network based at least in part on the one or more transient properties of the client device and the one or more connection properties of the host device and/or establish a connection with the host device in accordance with determining that the host device is capable of transmitting the data to the network.

Abstract: Communication between a source device and one or more pairs of accessory devices and between accessory devices within pairs of accessory devices is scheduled using slot availability masks (SAMs). A primary accessory device provides to the source device information about requirements for communication between the primary accessory device and a secondary accessory device. The source device determines a SAM map that specifies a periodic cycle of time slots, with time slots marked as available or unavailable for transmission and/or reception. The SAM map satisfies requirements to avoid collisions between communication between the source device and the accessory devices and communication between accessory devices within pairs of accessory devices. When multiple pairs of accessory devices establish connections with the source device, internal communication between accessory devices within pairs of accessory devices are aligned to use at least a common overlapping set of time slots.

Abstract: Apparatuses, systems, and methods broadcast a device state in a wireless communication network. A wireless audio output device is configured to be paired with a second wireless device via a first piconet connection, wherein the second wireless device comprises a source of audio data to be output by the wireless audio output device. The wireless audio output device includes a processor configured to detect a change in the state of the wireless audio output device and set a transmission parameter of a broadcast transmission based at least in part on the detected change in the state and a transceiver configured to broadcast an advertising message to the second wireless device including information describing the wireless audio output device via the broadcast transmission.
