Abstract

A communications device (100) and method (200) for automatically selecting features of accessories (120,140) operatively coupled to the communications device (100). In use the method (100) includes detecting operative coupling (220) of accessories (120,140) to the communications device (100) and then determining (240) a common feature supported by the accessories (120,140). Thereafter, the method (200) provides for selecting (250) one of the accessories (120,140) to provide the common feature the selecting (250) being determined by a sequence of the operative coupling.

Claims

1. A method for automatically selecting features of accessories operatively coupled to a communications device, the method comprising:

detecting operative coupling of at least two accessories to the communications device, the accessories being operatively coupled to respective accessory ports of the communications device;

determining a common feature supported by the accessories; and

selecting one of the accessories to provide the common feature to the communications device, the selecting being determined by a sequence of the operative coupling;

wherein the common features include a radio communications feature.

2. A method, as claimed in claim 1, wherein the detecting further includes storing the sequence of the operative coupling of the at least two accessories, wherein the accessories are a first coupled accessory and at least one further coupled accessory, the first coupled accessory being operatively coupled to the communications device before the further coupled accessory.

3. A method, as claimed in claim 1, wherein the selecting is characterized by the communications device directly controlling the common feature on a selected accessory.

4. A method, as claimed in claim 1, wherein the selecting is characterized by the selected accessory being addressed by use of an accessory identifier stored in an embedded memory of a selected accessory.

5. A method, as claimed in claim 1, wherein the selecting is characterized by selecting the second coupled accessory to provide the common feature to the communications device.

6. A method, as claimed in claim 1, wherein the storing includes allocating incremental count values associated with each of the accessories in an order in which the accessories are operatively coupled to the communications device.

7. A method, as claimed in claim 1, wherein the common features include audio communications.

8. A method, as claimed in claim 1, wherein the determining is characterized by comparing features identified in memory locations of embedded memories of each associated accessory.

9. A method, as claimed in claim 1, wherein the common features are features supported by the communications device without the accessories being coupled thereto.

10. A method, as claimed in claim 1, wherein the method includes a further step of re-selecting one of the accessories to provide the common feature to the communications device, the re-selecting being effected by removal of one of the accessories and the re-selecting being determined by the sequence of the operative coupling.

11. A communications device for automatically selecting features of accessories when operatively coupled thereto, the communications device comprising:

a processor;

a user interface operatively coupled to the processor; and

accessory ports operatively coupled to the processor, wherein in use when at least two accessories are operatively coupled to respective ones of the ports to allow communication between the accessories and the processor, the processor selects a selected one of the accessories to provide a common feature supported by the accessories, the selected one of the accessories being determined by a sequence in which the accessories were operatively coupled to the ports;

wherein the common features include a radio communications feature.

12. A communications device, as claimed in claim 11, wherein in use the processor stores the sequence of the at least two accessories being operatively coupled to respective ones of the ports, wherein the accessories are a first coupled accessory and at least one further coupled accessory, the first coupled accessory being operatively coupled to the communications device before the second coupled accessory.

13. A communications device, as claimed in claim 11, wherein the second coupled accessory provides the common feature.

14. A communications device, as claimed in claim 11, wherein the common feature is supported by the communications device without the accessories being coupled thereto.

15. A communications device, as claimed in claim 12, wherein in use the processor stores the sequence by allocating incremental count values associated with each of the accessories in an order in which the accessories are operatively coupled to the communications device.

16. A communications device, as claimed in claim 11 wherein in use the selected one of the accessories is determined by the processor comparing features identified in memory locations of embedded memories of each associated accessory that is operatively coupled to respective ones of the ports.

17. A communications device, as claimed in claim 12, wherein in use the processor provides for re-selecting one of the accessories to provide the common feature to the communications device, the re-selecting being effected by removal of one of the accessories and the re-selecting being determined by the sequence in which the accessories were operatively coupled to the ports.
