Abstract: The disclosure relates to performing a reliable broadcast from a source device to a plurality of nodes. In an aspect, a representative node establishes a first wireless communication link with each of one or more non-representative nodes, receives, from each of the one or more non-representative nodes, information indicating an ability of the one or more non-representative nodes to sniff wireless communications, establishes a second wireless communication link with the source device, configures the second wireless link based on the information received from the one or more non-representative nodes, sends control information for the second wireless communication link to each of the one or more non-representative nodes, and receives communications from the source device over the second wireless communication link, wherein the one or more non-representative nodes sniff the communications on the second wireless communication link based on the control information for that link.

Abstract: The present disclosure generally relates to wireless communication. Some aspects of the present disclosure include systems and techniques for device authentication. For example, an apparatus for wireless communication may receive, via a microphone, an audio signal from a second device. The apparatus may decode the audio signal to determine an encoded value. The apparatus may further determine that the audio signal is associated with the second device based on the encoded value. The apparatus may further establish a connection to the second device based on determining that the audio signal is associated with the second device.

Abstract: Various embodiments include systems and methods for balancing battery cycles of paired earbuds. A processor in an earbud charging case may receive battery level information from a first earbud operating in a deep sleep mode, determine a battery differential index (BDI) value, and send an instruction message to the first earbud indicating the first earbud should switch roles with a second earbud. An earbud may start a timer upon beginning to operate in a dormant mode, transition from operating in the dormant mode to operating in a non-dormant mode in response to expiration of the timer, send a message to a paired earbud indicating that the earbud has transitioned, and receive a message from the paired earbud indicating that the earbud should switch from operating in the dormant mode to operating in the deep sleep mode and periodically broadcasting an advertisement.

Abstract: There is a need to enable a wireless device to output signals such that the natural instincts of the user may be triggered. The present disclosure provides a solution by enabling a wireless device to determine a time delay and intensity difference associated with an audio output at a subset output devices based at least in part on a perceived spatial placement of at least one signal, a position of the transmitting device, and/or a signal strength associated with the signal. Using the time delay and the intensity difference, the output devices farthest from the transmitting device may output the at least one signal using the time delay and the intensity difference such that the user may detecting differences in the sound wave's time of arrival and intensity at the left ear versus the right ear, and thus, perceive the location of the audio source.

Abstract: The disclosure generally relates to using directionality to reduce flooding in a wireless mesh network. In an aspect, a node of the wireless mesh network receives a message for a destination node in the wireless mesh network, determines whether or not the message came from a direction of the destination node, drops the message based on determining that the message came from the direction of the destination node, and forwards the message based on determining that the message did not come from the direction of the destination node.
