Abstract: Embodiments of the current disclosure facilitate the creation of a wireless connection between a host device and an accessory device over a wireless medium. For instance, according to some embodiments, a method of connecting an accessory device to a host device includes transmitting a plurality of advertising beacons over a wireless medium. Each wireless beacon can contain information identifying a predetermined time when the accessory device will begin a page scan. The accessory device can begin the page scan at the predetermined time and can receive pages from a host device during a page scan window of the page scan over the wireless medium. The received pages can then be subsequently used to establish an ad hoc network connection between the accessory device and the host device.

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: 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: 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: 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: 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: Apparatus and methods to communicate audio data from either an active wireless device or a requesting wireless device to one or more audio reproduction devices that are simultaneously communicatively coupled to both the active wireless device and to the requesting wireless device are disclosed. Responsive to a request from the requesting wireless device to transmit audio data to the one or more audio reproduction devices, the active wireless device determines whether to transmit audio data from the requesting wireless device based at least in part on an audio status of the active wireless device and a set of predetermined arbitration criteria that prioritizes among applications and operating system processes that generate the audio data.
