Title
(EN) METHOD FOR POWER-SAVING FOR WIRELESSLY PAIRED DEVICES
(FR) PROCÉDÉ D'ÉCONOMIE D'ÉNERGIE POUR DISPOSITIFS APPARIÉS SANS FIL
Abstract
(EN)
The present disclosure provides for power conservation in truly wireless earbuds or other paired wireless devices, by switching a secondary device into a power save mode when the devices are not receiving traffic from the host. In this power-save mode the devices are put into a lower duty cycle than conventional configuration. The primary and secondary devices communicate over a backchannel communication link at a very low duty cycle, in some examples below lower bounds specified for standard communication with other devices. The primary earbud may be responsible for letting the secondary earbud know when to leave power-save mode and resume regular operation.

La présente invention concerne la préservation d'énergie dans des écouteurs réellement sans fil ou d'autres dispositifs sans fil appariés, par commutation d'un dispositif secondaire dans un mode d'économie d'énergie lorsque les dispositifs ne reçoivent pas de trafic de l'hôte. Dans le mode d'économie d'énergie selon l'invention, les dispositifs sont mis dans un rapport cyclique inférieur à la configuration classique. Les dispositifs primaire et secondaire communiquent sur une liaison de communication de canal de retour, à un rapport cyclique très faible, dans certains exemples au-dessous de limites inférieures spécifiées pour une communication standard avec d'autres dispositifs. Les écouteurs primaires peuvent être responsables de faire savoir à l'écouteur secondaire le moment où il quitte le mode d'économie d'énergie et reprend un fonctionnement normal.
