Wireless binaural hearing systems often communicate via connection-based networks. In such networks, communication gaps may lead to devices becoming disconnected from the network. Initialisation procedures executed to allow disconnected devices to participate on the network again, may cause prolonged pauses and/or delays in the audio signals presented to the user. The binaural hearing system 1 of the present invention comprises a left-ear hearing device L, a right-ear hearing device R and an auxiliary device S. The auxiliary device S has a connected mode wherein it transmits data messages 36, 37 and a disconnected mode wherein it does not transmit data messages 36, 37, and the auxiliary device S is adapted to enable the connected mode in dependence on receiving beacon messages 34, to synchronise its transmission of data messages 36, 37 with received beacon messages 34 and to enable the disconnected mode in dependence on not receiving beacon messages 34. To avoid disconnection of the auxiliary device S during gaps, the left-ear hearing device L and the right-ear hearing device R are adapted to alternatingly transmit the beacon messages 34. This allows for a more reliable and stable transmission of beacon messages 34 and thus for a more reliable network connection to auxiliary devices S, such that reconnection of auxiliary devices S will be required less frequently. |
