Abstract: Disclosed are techniques for detecting a security threat in a wireless mesh network. In an aspect, a monitoring device in the wireless mesh network detects a first message transmitted by a source node in the wireless mesh network to a destination node in the wireless mesh network via at least one relay node in the wireless mesh network, collects information from the first message as it is transmitted in the wireless mesh network, determines that the first message has been corrupted based on analysis of the information from the first message, and detects the security threat in the wireless mesh network based on the first message being corrupted.

Abstract: Two devices (e.g., two wireless Bluetooth earbuds) may exchange device address information (e.g., Bluetooth address information) and may identify a primary address. When either of the devices connect to a source device (e.g., a phone), the primary address may be used by the connecting device such that the pair of devices appear as a single device (e.g., a Bluetooth-pairable device) to the source device, regardless of the device connecting to the source device as the primary device. The primary device may then send identity information (e.g., that has been exchanged with the secondary device) to the source device, such that the source device may connect to either of the two devices. Further, once a primary device connects to the source device, the primary device may transmit, to the secondary device, connection information such that the secondary device may connect to the source device and operate in the primary role.

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: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for initiating, at a first wireless audio device, a handover interval including one or more extended synchronous connection-oriented (eSCO) windows, buffering a set of one or more audio (e.g., microphone) data packets during the handover interval, discarding at least a portion of the set of one or more audio data packets during the handover interval, receiving a handover indication from a second wireless audio device during an extended retransmission portion of a first eSCO window of the handover interval, and transmitting one or more audio data packets during a second eSCO window that is subsequent to the handover interval.

Abstract: A first Bluetooth audio device paired with a second Bluetooth audio device may coordinate communications between the two BT audio devices. The first Bluetooth audio device may originally communication with the second BT audio device over a first type of Bluetooth connection. When the first Bluetooth audio device determines that the second Bluetooth audio device has left or is close to leaving the range of the first Bluetooth audio device, the first Bluetooth audio device may switch to communicating with the second Bluetooth audio device over a second type of Bluetooth connection or over a wireless mesh network. The first Bluetooth audio device may maintain a Bluetooth connection of the first type with a mobile device regardless of how the first Bluetooth audio device communicates with the second Bluetooth audio device.

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: Disclosed are techniques for establishing an encrypted connection between a first node and a second node in a wireless mesh network. In an aspect, the first node receives, from a provisioner node in the wireless mesh network, a first value encrypted with a device-specific encryption key known only to the first node and the provisioner node, wherein the second node receives, from the provisioner node, the first value encrypted with a second device-specific encryption key, generates a friendship-specific encryption key based on the first value, an identifier of the first node, and an identifier of the second node, wherein the second node generates the friendship-specific encryption key, sends, to the second node, a first message encrypted with the friendship-specific encryption key, and receives, from the second node, a second message encrypted with the friendship-specific encryption key.
