Hearing aid wireless network
First Claim
1. A hearing aid comprising a transceiver for interconnection of the hearing aid with a wireless network, and a communication controller that is adapted for controlling data exchange through the network in accordance with a network protocol, and wherein the controller is further adapted for initialisation of the network in an acquisition mode by controlling the transceiver to transmit interrogation data repetitively, and upon receipt of an interrogation data received message from another device, in a connected mode acting as a master of the network by repetitively transmitting synchronization data at intervals that are longer than the intervals between transmitted interrogation data in the acquisition mode.

Abstract
A hearing aid is provided comprising a transceiver for interconnection of the hearing aid with a wireless network for communication with a plurality of other devices, and a communication controller that is adapted for controlling data exchange through the network in accordance with a simple network protocol. The hearing aid wireless network facilitates interconnection of a plurality of devices in the network, such as hearing aids, remote controllers, fitting instruments, mobile phones, headsets, door bells, alarm systems, broadcast systems, such as tele coil replacement, etc, etc. In an established network, the network master device, in a connected mode, regularly transmits synchronization data, e.g. comprised in a link management package, for synchronization of the slave devices in the network with the master device. During initialisation of the network, for example upon turn-on of two hearing aids, each device in an acquisition mode transmits interrogation data, e.g. comprised in a link management package, at a higher rate than the rate of transmission of the synchronization data in the connected mode. The provided acquisition method has low power consumption during execution and it is fast.
