Synchronizing asynchronous dual-stack radio events for hearing device applications

Abstract:

A battery-powered mobile hearing assist device allows concurrent wireless transception of control data via standard Bluetooth low energy ("BLE"), such as a smartphone, and proprietary audio streaming ("PAS") from a second device such as a wireless audio streaming accessory. Power savings are achieved particularly in situations where the hearing device is searching for the PAS device. Instead of performing PAS search events as a separate wireless activity from the BLE advertising or connection events, including waking and ramping up for each of the BLE and PAS protocols, PAS search events are combined into the BLE advertising or connection events before returning to the sleep mode in each connection interval, eliminating duplicative processor steps, ramp up and/or ramp down.
