Abstract: This disclosure provides methods, devices, and systems for streaming media from a Bluetooth-enabled peripheral device to a WLAN device over a wireless link (such as a P2P link). In some instances, a first peripheral device of a pair of peripheral devices selects values of a time-to-play (TTP) and a sequence number of a first audio stream, and synchronizes the selected TTP and sequence number with a TTP and a sequence number of a second audio stream. The first peripheral device rate-converts first audio data using a sample rate conversion ratio based on the selected TTP and sequence number, encapsulates the rate-converted first audio data into first RTP packets, and transmits the first RTP packets to the WLAN device concurrently with a transmission of second RTP packets from the second peripheral device to the WLAN device.

Abstract: A wireless device establishes a Bluetooth connection with a peripheral device based on one or more Bluetooth Specifications, and transmits one or more first Bluetooth-encoded data frames to the peripheral device over the Bluetooth connection. The wireless device initiates a first handover operation for communications with the peripheral device responsive to a link metric of the Bluetooth connection being less than a first link metric threshold. In some instances, the first handover operation includes selecting an access point (AP) of one or more candidate APs based on signal strengths of frames received from the one or more candidate APs, and switching the communications between the wireless device and the peripheral device from the Bluetooth connection to a wireless local area network (WLAN) channel associated with the selected AP. The wireless device transmits one or more second Bluetooth-encoded data frames to the peripheral device over the WLAN channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, via a wireless link, with an audio device using a first configuration having first values for communication parameters. The WCD may transmit an indication to switch to a second configuration based at least in part on a configuration switch trigger, the configuration switch trigger being based at least in part on one or more of a link quality metric associated with the wireless link or a change of a use state of the WCD, and the second configuration having second values for the communication parameters associated with a reduction in voltage-induced interference in an audio output of the audio device. Numerous other aspects are described.

Abstract: This disclosure describes techniques for allowing a wireless device and a peripheral device to enter a sleep state while maintaining an active WLAN link between the wireless device and the peripheral device. In some implementations, the wireless device operates as a STA associated with a WLAN while also operating as a softAP. The wireless device selects a sleep state beacon interval based on a handover request, and obtains a next sleep state TBTT based on the sleep state beacon interval and a TSF value of the wireless device. The wireless device sends a message to the peripheral device over the Bluetooth connection, the message indicating the next sleep state TBTT and the sleep state beacon interval, and transmits one or more beacon frames to the peripheral device over the WLAN link during the sleep state based on the next sleep state TBTT and the sleep state beacon interval.

Abstract: A method, apparatus, and computer-readable medium are provided that improve power management for devices communicating via Bluetooth (BT) over Internet Protocol (BTOIP). The apparatus for wireless communication for a first device receives a first set of packets from a second device during a time period associated with a training phase for the first device. The apparatus determines an arrival time of a first packet of the first set of packets. The apparatus determines, based on the arrival time and a wakeup time interval, a wakeup time for the first device. The apparatus causes, based on the wakeup time for the first device and one or more attributes associated with the first set of packets, a shutdown of the first device.
