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.
