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.
