Abstract

The invention relates to a method and a technical equipment for short range data transmission, e.g. Bluetooth low energy. The method comprises receiving, as a response to a transmitted advertisement packet, a scan request from a scanning device; reporting the scan request from a link layer to an application layer; determining a following action according to the scan request and performing the determined action.

Claims

1. A method, comprising

receiving, as a response to a transmitted advertisement packet, a scan request from a scanning device;

reporting the scan request from a link layer to an application layer; and

determining a following action according to the scan request and performing the determined action.

2. The method according to claim 1, wherein the following action is to modify a scan response packet to be sent to the scanning device.

3. The method according to claim 1, wherein the following action is to modify an advertisement packet to be transmitted.

4. The method according to claim 1, wherein the following action is to select a certain scan response to be transmitted from a group of different scan response packets, which selection is based on the scan request.

5. The method according to claim 1, wherein the following action is to change an operation mode.

6. The method according to claim 1, wherein the scan request packet contains data on the address of scanning device.

7. The method according to claim 2, wherein the scan response packet contains data on the address of a target device for the scan request packet, and information on the services the target device for the scan request packet is able to provide.

8. The method according to claim 1, wherein the method is carried out in a Bluetooth low energy enabled device.

9. An apparatus, comprising a processor means and a non-transitory memory including computer program code, wherein the memory and the computer program code are configured to perform with the processor, cause the apparatus at least to

receive, as a response to a transmitted advertisement packet, a scan request from a scanning device;

report the scan request from a link layer to an application layer; and

determine a following action according to the scan request and perform the determined action.

10. The apparatus according to claim 9, wherein the following action is to modify a scan response packet to be sent to the scanning device.

11. The apparatus according to claim 9, wherein the following action is to modify an advertisement packet to be transmitted.

12. The apparatus according to claim 9, wherein the following action is to select a certain scan response to be transmitted from a group of different scan response packets, which selection is based on the scan request.

13. The apparatus according to claim 9, wherein the following action is to change an operation mode.

14. The apparatus according to claim 9, wherein the scan request packet contains data on the address of scanning device.

15. The apparatus according to claim 10, wherein the scan response packet contains data on the address of a target device for the scan request packet, and information on the services the target device for the scan request packet is able to provide.

16. The apparatus according to claim 9, wherein the apparatus is a Bluetooth low energy enabled device.

17. A system, comprising at least one advertising device and at least one scanning device, wherein said at least one advertising device is configured to

receive, as a response to a transmitted advertisement packet, a scan request from said at least one scanning device;

report the scan request from a link layer to an application layer; and

determine a following action according to the scan request and perform the determined action.

18. A computer program product embodied on a computer readable medium, comprising computer program code configured to, when executed on at least one processor, cause an apparatus or a system to:

receive, as a response to a transmitted advertisement packet, a scan request from a scanning device;

report the scan request from a link layer to an application layer; and

determine a following action according to the scan request and perform the determined action.
