摘要： 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.

摘要： Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

摘要： A first device may communicate via a first wireless interface (WI) and a second WI, with the second WI operating at a relatively higher power level than the first WI. The first device may receive a scan notification corresponding to wireless scanning performed by a second device. The first device may subsequently perform wireless scanning using the second WI in response to the scan notification indicating that the first device is within effective communication range of a third device. The first device may receive the scan notification over a wireless connection established between the first device and the second device using the first WI. The first device may transmit filter information to the second device, the filter information indicating when, and for which scans the first device is to receive scan notifications. The first device may also activate the second WI and use the second WI to perform ranging and/or control operations associated with the third device.

摘要： Exemplary embodiments include a system having a first device and a second device that are configured to establish a connection via a short-range protocol. The first and second devices perform an advertisement process to automatically identify that the first and second devices are capable of establishing the connection, the advertisement process comprising one of the first device or second device broadcasting an advertisement and the other one of the first device or the second device scanning for the advertisement, wherein, upon the first and second devices identifying that they are capable of establishing the connection, the first and second devices perform a paging mechanism to establish the connection, the paging mechanism comprising one of the first device or the second device transmitting a page and the other one of the first device or the second device scanning for the page, wherein the page triggers an operation to establish the connection.

摘要： In order to reduce the power consumption after a transmitting electronic device in a wireless network has been detected, a receiving electronic device calculates transmit times of subsequent beacons from the transmitting electronic device based on a clock drift of the transmitting electronic device and the beacon period. Then, the receiving electronic device receives the subsequent beacon by opening scan windows that encompass the calculated transmit times. However, because the transmit times are more predictable after the transmitting electronic device has been detected (and the clock drift of the transmitting electronic device is known to the receiving electronic device), the receiving electronic device can reduce the width of the scan windows. In addition, the transmitting electronic device can further reduce the power consumption by increasing the beacon period.

摘要： 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.

摘要： Methods and apparatus for communicating audio packets with ultra-low latency at high data rates from an audio source device to one or more audio output devices over a wireless personal area network (WPAN) connection, such as via a Bluetooth connection. Latency is reduced by using time-efficient audio coding and decoding, limited retransmissions, reduced time and frequency of acknowledgements, and by combining Bluetooth Classic (BTC) packets for downlink audio and downlink control with Bluetooth Low Energy (BTLE) packets for uplink control, uplink acknowledgements, and inter-device wireless communication. The number of retransmissions and packet concealments per frame cycle can be limited to an upper threshold number to satisfy a low latency requirement.

摘要： A sink device is configured to establish a Bluetooth connection with a source device. The sink device receives a transmission from the source device that includes a plurality of data blocks, an item of check information, and a plurality of parity blocks during a transmission time duration. The sink device determines, prior to receiving an entirety of the transmission, whether at least one of received data blocks includes an error based on at least the item of check information and, when the at least one of the received data blocks includes the error and prior to receiving all of the plurality of parity blocks, the sink device performs an error correction operation on a first one of the received data blocks based on a first one of the parity blocks.
