Embodiment Construction

[0100] In the following, various examples of methods and hearing devices are shown. However the methods and hearing devices according to the appended claims may be embodied in different forms and should not be construed as limited to the examples described herein.

[0101] It should be noted that the figures are schematic and simplified for clarity, and that they only show details necessary for the understanding of the method and hearing aid, while other details have been left out.

[0102] Like reference numerals refer to like elements throughout. Similar elements will therefore not be described in detail with respect to each drawing.

[0103] figure 1 A binaural hearing aid system is schematically shown comprising a left ear hearing aid 10L and a right ear hearing aid 10R, each of which includes an audio-enabled communication device (such as a smart phone or mobile phone, an audio-enabled tablet computer, a cordless phone) to another audio-enabled communication device. ,...

Abstract

A new method of wireless communication of data, e.g. with different priorities, is provided, for example in compliance with a Bluetooth Low Energy (LE) standard. A new hearing device configured for wireless communication in accordance with the new method is also provided.

Description

technical field [0001] A method is provided for wireless communication of data, for example in accordance with the Bluetooth Low Energy (LE) standard, with different priorities. A hearing device configured for wireless communication according to the method is also provided. Background technique [0002] Bluetooth LE, as defined by Bluetooth Core Specification 4.1 or earlier, does not allow audio transmission. There are many limitations in the protocol as defined, which means that audio transmission is not feasible without changing some protocol layers: [0003] - As defined by the nature of L2CAP channels for LE, where a best effort method of data delivery without send timeouts or flushes is defined, this property also means that it is nearly impossible to do realtime audio over LE as defined Serve. [0004] - The lack of a real-time transmission method also means that stereo synchronization between two pairs of audio receivers (such as hearing aids) is almost impossible....
