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.

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.

13. A method of wireless communication between a first device and a second device of a hearing prosthesis, comprising:
-
selecting, by said second device, a frequency channel for bidirectional wireless communication from a predefined series of frequency channels; sending a command from said first device repeatedly over a plurality of frequency channels comprising the frequency channel selected by said second device, until a reply signal is received by said first device; and using said frequency channel selected by said second device as one of a few initial frequency channels to transmit a subsequent command to said second device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of wireless communication between multiple devices of a hearing prosthesis, the hearing prosthesis comprising a first device, a second device and a third device, wherein the method comprising:
-
transmitting a signal from the first device to the second device; receiving the signal by the second device, optionally modifying the signal in a predetermined manner and transmitting the signal, unmodified or modified in a predetermined manner, from the second device to the third device; receiving the signal by the third device, optionally modifying the signal in a predetermined manner and transmitting the signal, unmodified or modified in a predetermined manner, from the third device to the first device and receiving the signal by the first device and comparing the signal that is received with the signal that was transmitted. - View Dependent Claims (22)
