Abstract
Devices and methods for connected isochronous stream (CIS) swapping are disclosed. In an example Bluetooth™ setting, a smartphone can be connected to multiple earbuds. It is possible that both earbuds include microphones, but only one microphone is enabled at a given time. That is, only one of the CISes established between the smartphone and the earbuds is bidirectional, and the other is unidirectional. The disclosed techniques enable the CISes to be swapped between the earbuds so that the earbud with better microphone quality will have ownership of the bidirectional CIS.
