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.

Abstract: Two different wireless protocols can be used for ranging between a mobile device and an access control system (e.g., a vehicle). The first wireless protocol (e.g., Bluetooth®) can be used to perform authentication of the vehicle and exchange ranging capabilities between a mobile device (e.g., a phone or watch) and the vehicle. The second wireless protocol (e.g., ultra-wideband, UWB) can use a pulse width that is less than a pulse width used by the first wireless protocol (e.g., 1 ns v. 1 μs). The narrower pulse width can provide greater accuracy for distance (ranging) measurements.

Abstract: The embodiments set forth herein disclose techniques for enabling a user device to seamlessly establish a secure, high-bandwidth wireless connection with a vehicle accessory system to enable the user device to wirelessly stream user interface (UI) information to the vehicle accessory system. To implement this technique, a lower-bandwidth wireless technology (e.g., Bluetooth) is used as an initial means for establishing a Wi-Fi pairing between the user device and the vehicle accessory system. Wi-Fi parameters associated with a Wi-Fi network provided by the vehicle accessory system can be communicated to the user device using the lower-bandwidth wireless technology. A secure Wi-Fi connection can then be established between the user device and the vehicle accessory system using the provided Wi-Fi parameters. The embodiments also disclose a technique for enabling the user device to automatically reconnect with the vehicle accessory system in a seamless manner (e.g., when returning to a vehicle).

Abstract: A host device may include a first wireless communication circuit, a second wireless communication circuit including a proxy router, and a host processor communicatively coupled to the wireless communication circuits. The host device may receive, via the second wireless communication circuit, an advertisement message from a client device. The advertisement message may include a request for communication of data with a network. The host device may determine at least one of a communication policy preference of the host device and a network connection property of the host device. The proxy router may select the first or the second wireless communication circuit for use by the host device to communicate the data with the network. The host device may provide, via the second wireless communication circuit, a connection request to the client device, and then transfer, using the selected wireless communication circuit, the data between the client device and the network.

Abstract: A host device communicating with a plurality of accessory devices transmits audio data packets via a broadcast channel to the plurality of accessory devices. When one of the plurality of accessory devices determines an audio data packet has not been received, the accessory device sends a negative-acknowledgement signal (NACK) via a unicast channel. The NACK indicates that the at least one of the accessory devices did not receive at least one audio data packet. The host device retransmits the at least one audio data packet indicated as not being received via the broadcast channel to the plurality of accessory devices. Other aspects are also described and claimed.

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: An apparatus and methods are provided for initiating a network connection between a first device and a second device. While one or more high-power network interfaces of the first device are in a dormant state, the first device communicates with a second device via the first device's low-power network interface. The first device can determine, based on the communication, whether to establish a network connection with the second device via a high-power network interface of the first device. Next, if the first device is to establish the network connection with the second device via the high-power network interface, the device can wake the first high-power network interface and connect to the second device via the first high-power network interface.

Abstract: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

Abstract: A system and method for routing communication to a common audio output device connected to each of two or more audio signal source devices. For each of the two or more audio signal source devices, a set of inputs are assessed. The set of inputs include: an operational state of the audio signal source device, an activity the audio signal source device, an audio-producing application being executed by the audio signal source device, and a degree of user activity with the audio-producing application being executed by the audio signal source. At a point in time, an audio routing score is generated for each of the two or more audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the two or more audio signal source devices to the audio output device, based on the audio routing score for each of the two or more audio signal source devices.
