Wireless communication between devices of a hearing prosthesis

Abstract

A method of wireless communication between hearing aid devices of a hearing prosthesis. A first device selects a frequency channel for bidirectional wireless communication from a predefined series of frequency channels. A second device transmits a command signal repeatedly over the series of frequency channels until it transmits the command signal over the frequency channel selected by the first device. Subsequent commands send by the second device to the first device are initially transmitted over the selected frequency channel.

1 . A hearing prosthesis comprising a first device and a second device arranged for receiving commands from said first device, wherein:
 said first and the second devices each comprise a transmitter and receiver system configured for communication over a wireless communications link;   said second device is configured to select a frequency channel for bidirectional wireless communication from a predefined series of frequency channels;   said first device is configured to transmit a command signal repeatedly over a plurality of frequency channels comprising the frequency channel selected by said second device; and   said first device is further configured to initiate transmission of a subsequent command over said frequency channel selected by said second device.
