Systems, methods, and non-transitory computer-readable storage media for performing a role swapping operation between a pair of non-tethered wireless ear buds after detecting a triggering event. Further, state information can be coordinated between devices, including in connection with performing a role swap between buds in a pair of wireless, untethered ear buds, where one wireless ear bud is in a primary role and is responsible for a connection with a companion device, and another wireless ear bud in the pair is in a secondary role.

Swapping roles between untethered wirelessly connected devices

Exemplary embodiments include a system having a first wireless audio output device configured to connect to a source device via a first piconet and a second wireless audio output device configured to connect to the first wireless audio output device via a second piconet. A schedule of the first piconet includes a plurality of slots associated with an audio packet, a first subset of the slots used by the source device to transmit the audio packet, the first and second wireless audio output devices tuning to the first piconet to listen for the transmissions of the audio packet, and when, after a last one of the first subset of slots, the first or second wireless audio output devices did not receive the audio packet, the first and second wireless audio output devices exchange information via the second piconet such that the both wireless audio output device receive the audio packet.

Real-time relay of wireless communications

An electronic device that communicates with a second electronic device using adaptive frequency hopping across different spectral bands is described. An integrated circuit in the electronic device includes processing logic that determines an adaptive spectral map that specifies channels across multiple spectral bands. During communication with a second electronic device that includes a second integrated circuit using a communication protocol (such as Bluetooth or Bluetooth Low Energy), the integrated circuit selects channels in the adaptive spectral map, where selection can be based on a predefined frequency-hopping sequence.
