Abstract

The present invention provides an adaptor, system and a method for allowing a communications device to accept a connection from a Bluetooth enable device. This is achieved by coupling the communications device to an adaptor which is configured to accept a Bluetooth connection from a Bluetooth enable device. The communications device periodically generates a connection request signal which is transferred to the adaptor. Once the Bluetooth connection has been established, the adaptor then establishes a connection with the communications deformed between the communications device and the Bluetooth enable device, with the communications device acting as a slave.

Claims

1. A Bluetooth adaptor for allowing a communications device to accept a connection from a Bluetooth enabled device, the communications device having an output which periodically outputs a connection request signal, the adaptor comprising:

an input for coupling to the output;

a radio for providing Bluetooth connectivity; and

,

a processor coupled to the input and the radio, wherein, in use the processor is adapted to;

cause a Bluetooth connection to be established in response to a connection request from the Bluetooth enabled device; and

,

once the Bluetooth connection has been established, cause a connection to be established with the communications device via the input in response to a connection request signal received at the input.

2. An adaptor according to claim 1, wherein the communications device is adapted to communicate in accordance with a first communications protocol, and wherein the Bluetooth enabled device is adapted to communicate in accordance with a second communications protocol, the processor being further adapted to translate data between the first and second protocols as required.

3. An adaptor according to claim 1 or claim 2, wherein the input is adapted to couple to the output of a PDA.

4. An adaptor according to any of the preceding claims, wherein the adaptor further comprises a store for storing data to be transferred between the Bluetooth enabled device and the communications device.

10. A system according to any of claims 5 to 9, wherein the adaptor is an adaptor according to any of claims 1 to 4.

5. A system for allowing a communications device to accept a connection from a Bluetooth enabled device, the system comprising:

a communications device having;

an output; and

,

a processor coupled to the output, the processor being adapted to periodically generate a connection request signal at the output,

adaptor having;

an input for coupling to the output;

a radio for providing Bluetooth connectivity; and

,

an adaptor processor coupled to the input and the radio, wherein, in use the processor is adapted to;

cause a Bluetooth connection to be established in response to a connection request from the Bluetooth enabled device; and

,

once the Bluetooth connection has been established, cause a connection to be established with the communications device via the input in response to the connection request signal received at the input.

6. A system according to claim 5, wherein the communications device is a PDA.

7. A system according to claim 5 or claim 6, wherein the output is for coupling to a modem, the connection request signal being a modem connection request signal.

8. A system according to any of claims 5 to 7, wherein the processor is adapted to periodically generate the connection request signal in response to a request from the user of the communications device.

9. A system according to any of claims 5 to 8, wherein the communications device is adapted to communicate in accordance with a first communications protocol, and wherein the Bluetooth enabled device is adapted to communicate in accordance with a second communications protocol, the adaptor processor being further adapted to translate data between the first and second protocols as required.

11. A method of causing a communications device to accept a connection from a Bluetooth enabled device, the method comprising:

coupling the communications device to an adaptor;

causing the communications device to periodically output a connection request signal;

causing the adaptor to accept a Bluetooth connection from the Bluetooth enabled device in response to a connection request; and

,

once the Bluetooth connection has been established, causing the adaptor to establish a connection with the communications device in response to a connection request from the communications device.

12. A method according to claim 11, wherein the method further comprises causing the communications device to periodically output a connection request signal in response to a request from the user of the communications device.

13. A method according to claim 11 or claim 12, wherein the adaptor accepts a Bluetooth connection from the Bluetooth enabled device by:

monitoring for a connection request signal from the Bluetooth enabled device; and

,

generating a response indicating that the connection is to be accepted.

14. A method according to any of claims 11 to 13, wherein the communications device is adapted to communicate in accordance with a first communications protocol, and wherein the Bluetooth enabled device is adapted to communicate in accordance with a second communications protocol, the method further comprising causing the adaptor to translate data between the first and second protocols as required.
