Method and technical equipment for short range data transmission
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.
1. A method, comprising receiving, as a response to a transmitted advertisement packet, a scan request from a scanning device, wherein the scan request does not include a payload; reporting the scan request from a link layer to an application layer; and after reporting the scan request to an application layer, 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 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.
4. The method according to claim 1 , wherein the following action is to modify an advertisement packet to be transmitted.
5. 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.
6. The method according to claim 1 , wherein the following action is to change an operation mode.
7. The method according to claim 1 , wherein the scan request packet contains data on the address of scanning device.
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 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, wherein the scan request does not include a payload; report the scan request from a link layer to an application layer; and after reporting the scan request to an application layer, to 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 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.
12. The apparatus according to claim 9 , wherein the following action is to modify an advertisement packet to be transmitted.
13. 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.
14. The apparatus according to claim 9 , wherein the following action is to change an operation mode.
15. The apparatus according to claim 9 , wherein the scan request packet contains data on the address of scanning device.
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, wherein the scan request does not include a payload; report the scan request from a link layer to an application layer; and after reporting the scan request to an application layer, to determine a following action according to the scan request and perform the determined action.
18. A computer program product embodied on a non-transitory 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, wherein the scan request does not include a payload; report the scan request from a link layer to an application layer; and after reporting the scan request to an application layer, to determine a following action according to the scan request and perform the determined action.
