Abstract

A method and an associated configuration transmit data between a hearing device and an external unit. A first data packet is transmitted to the hearing device by the external unit. The first data packet is received by the hearing device and a second data packet is transmitted from the hearing device to the external unit. A predefinable fixed period of time elapses between the end of the receipt of the first data packet and the start of transmission of the second data packet. The external unit thereby “knows” when the first bit of the second data packet is to arrive. This offers the advantage that the reliability of a data transmission is improved. In the case of a packet-oriented data transmission fewer data packet repetitions are required, as a result of which the transmission speed increases.

Claims

1. A method for transmitting data between a hearing device and an external unit, which comprises the steps of:

transmitting a first data packet from the external unit to the hearing device;

receiving the first data packet in the hearing device; and

transmitting a second data packet from the hearing device to the external unit after a predefinable fixed period of time based on a received synchronization sequence following an end of a receipt of the first data packet, the predefinable fixed period of time being stored in the external unit and in the hearing device, and the external unit knowing when a first bit of the second data packet arrives based on the predefinable fixed period of time, during the transmitting of the second data packet from the hearing aid to the external unit.

2. The method according to claim 1, which further comprises performing the transmitting steps wirelessly.

3. The method according to claim 1, wherein the first data packet contains a synchronization sequence, with which a clock skew in the hearing device is corrected.

4. A configuration for wireless transmission of data, comprising:

a hearing device storing a predefinable fixed period of time; and

an external unit storing the predefinable fixed period of time, said external unit and said hearing device programmed to;

transmit a first data packet from said external unit to said hearing device;

receive the first data packet in said hearing device; and

transmit a second data packet from said hearing device to said external unit after the predefinable fixed period of time based on a received synchronization sequence following an end of a receipt of the first data packet, said external unit knowing when a first bit of the second data packet arrives based on the predefinable fixed period of time during a transmission of the second data packet from said hearing aid to said external unit.

5. The configuration according to claim 4, wherein said external unit is a hearing device remote control.

6. The configuration according to claim 4, wherein:

said hearing device has a first radio module; and

said external unit has a second radio module.
