Abstract

Bluetooth standard provides the applications with different profiles which allow for example only a specific number of devices operable in one network using the same profile. Without changing the Bluetooth standards the described apparatus and method provide a solution to allow wireless devices to receive data addressed to other wireless devices. Therefore a wireless electronic apparatus for Bluetooth communication receives data specifically addressed to said wireless electronic apparatus and to a wireless electronic device for Bluetooth communication, said wireless electronic device being operable to receive data specifically addressed to said wireless electronic device, said wireless electronic apparatus being different from said wireless electronic device. This can be realised for example by a wrist display which can pickup the electromagnetic waves containing the audio signals sent to the headset. Afterwards the properties can be displayed on the wrist to inform the user about the status of the audio signals or the cell phone transmitting the audio signals.

Claims

1. A wireless electronic apparatus for Bluetooth communication in a Bluetooth network comprising:

a Bluetooth receiver that receives data specifically addressed to said wireless electronic apparatus and to a wireless electronic device for Bluetooth communication, said specifically addressed data comprising a device address code of said wireless electronic device which is different from an address code of said wireless electronic apparatus, said wireless electronic device comprising a receiver for receiving data specifically addressed to said wireless electronic device, the Bluetooth receiver being configured to receive the device address code of said wireless electronic device during manufacture of the electronic apparatus or from the wireless electronic device or a radio device while the network is formed;

a Bluetooth transmitter for transmitting data, said wireless electronic apparatus operable based on the received device address code to personate as said wireless electronic device when transmitting data so as to appear to a receiving device as originating from said wireless electronic device, said wireless electronic apparatus being different from said wireless electronic device.

2. A wireless electronic apparatus for Bluetooth communication according to claim 1, wherein the Bluetooth transmitter is configured to send data specifically addressed as said wireless electronic apparatus or as said wireless electronic device for Bluetooth communication.

3. A wireless electronic system for Bluetooth communication forming a Bluetooth network with a radio device comprising a transmitter for transmitting and a receiver for receiving specifically addressed data, said system comprising

a wireless electronic device which receives and transmits specifically addressed data, wherein said wireless electronic device comprises a Bluetooth receiver that receives said data, said data being specifically addressed to said wireless electronic device and comprising a device address code of said wireless electronic device, and

a wireless electronic apparatus according to claim 1.

4. A wireless electronic system for Bluetooth communication according to claim 3, wherein the Bluetooth transmitter of the wireless electronic apparatus is configured to transmit data specifically addressed as said wireless electronic apparatus or as said wireless electronic device.

5. A wireless electronic system for Bluetooth communication according to claim 3, wherein the wireless electronic device transmits specifically addressed data to said radio device.

6. A wireless electronic system for Bluetooth communication according to claim 3, wherein the wireless electronic device and the wireless electronic apparatus each further comprises a processor to process data streams and/or data packets, respectively.

7. A wireless electronic system for Bluetooth communication according to claim 3, wherein the wireless electronic device and the wireless electronic apparatus are spatially separated.

8. A wireless electronic system for Bluetooth communication according to claim 3, wherein the wireless electronic apparatus is provided the device address code of the wireless electronic device while the network is formed, said device address code for receiving data specifically addressed to the wireless electronic device.

10. A wireless electronic apparatus according to claim 1, wherein said Bluetooth receiver of said wireless electronic apparatus receives said data comprising said device address code of said wireless electronic device in parallel with said receiver of said wireless electronic device.

9. A method for receiving data by a wireless electronic apparatus for Bluetooth communication from a radio device, said wireless electronic apparatus comprising a transmitter for transmitting and a receiver for receiving data, wherein the data is specifically addressed to a wireless electronic device for Bluetooth communication, said specifically addressed data comprising a device address code of said wireless electronic device which is different from an address code of said wireless electronic apparatus, said wireless electronic device comprising a receiver for receiving data, said wireless electronic apparatus being different from said wireless electronic device,

said wireless electronic apparatus comprising a receiver that receives said data in parallel with said receiver of said wireless electronic device, said data being specifically addressed to said wireless electronic device and comprising said device address code of said wireless electronic device,

the method comprising:

an initialization step, wherein the wireless electronic device connects to the radio device via an active Bluetooth connection, whereby an active device address is given from the radio device to the wireless electronic device, said active device address allowing the reception of specifically addressed data,

an adaptation step, wherein the wireless electronic apparatus receives the active device address from or during the initialization step to make the wireless electronic apparatus operable to receive and process data destined for the wireless electronic device, and

a reception step, wherein the wireless electronic apparatus receives data specifically addressed to the wireless electronic device.

11. A method of claim 9, comprising transmitting data, by said wireless electronic apparatus, to said radio device, the wireless electronic apparatus personating as said wireless electronic device when transmitting data so as to appear to said radio device as originating from said wireless electronic device.
