Abstract: The disclosure relates generally to wireless communication, and more particularly to selective relay of data packets. A method includes listening to a host device in one or more listening time slots of a host piconet, identifying one or more bitmap portions of a bitmap, wherein the identified one or more bitmap portions corresponds to the one or more listening time slots of the host piconet, determining whether a data packet having a data packet payload is effectively received from the host device during the one or more listening time slots, and populating the bitmap with one or more corresponding signifiers.

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: Methods, systems, and devices for wireless communications at a wireless audio device are described. A first (e.g., primary) wireless audio device may initiate a role switch procedure with a second (e.g., secondary) wireless audio device. The first wireless audio device may disable traffic flow between the source device and the first wireless audio device and transmit synchronization information and timing information necessary for taking over the role of primary wireless audio device to the second wireless audio device. The first wireless audio device may transmit a device role switch message, and the first wireless audio device and the second wireless audio device may perform the role switch. After performing the role switch, the first wireless audio device may assume the role of a secondary wireless audio device and the second wireless audio device may assume the role of a primary wireless audio device.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include determining that a quality condition of a primary Bluetooth-enabled device is lower than a quality condition of a secondary Bluetooth-enabled device. The primary Bluetooth-enabled device may transmit, to the secondary Bluetooth-enabled device, a handover request message based on the determining. The handover request message may include a subset of connection information associated with a connection between the primary Bluetooth-enabled device and a device in wireless communications with the primary Bluetooth-enabled device. The primary Bluetooth-enabled device may receive, from the secondary Bluetooth-enabled device, a handover response message based on the handover request message. As a result, the primary Bluetooth-enabled device may handover, to the secondary Bluetooth-enabled device, at least one logical transport channel of the set of logical transport channels based on the handover response message.

Abstract: The disclosure relates generally to wireless communication, and more particularly to selective relay of data packets. A method includes receiving one or more received data packets from a series of transmitted data packets that are transmitted from a host device over a host piconet during a plurality of listening time slots of the host piconet; receiving a bitmap over a primary/secondary piconet, wherein the bitmap includes a plurality of bitmap portions and each bitmap portion respectively corresponds to one of the plurality of listening time slots of the host piconet; analyzing the received bitmap to identify one or more missed data packets from the series of transmitted data packets that were not received from the host device; and generating a relay list of missed data packets based on the analyzing of the bitmap.
