Abstract: Methods, systems, and devices for wireless communications are described. A device may communicate with a second device, which may be a Bluetooth device, using a relay profile (e.g., a low energy (LE) isochronous (ISO) relay profile). In accordance with broadcast discovery signaling by the device and decisions made by the Bluetooth device, the device may synchronize to a broadcast isochronous stream (BIS) from another device. The device may then establish a communication link with the second device (e.g., a synchronous connection oriented (SCO) link, an enhanced synchronous connection oriented (eSCO) link, an asynchronous connection less (ACL) link) to be used for relay of the BIS. The device may then convert, based on the relay profile, broadcast isochronous data packets of the BIS to SCO packets, eSCO packets, and/or ACL packets, and relay the converted packets to the second device via the established communication 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.
