Access control system with dynamic performance tuning

1. A method of dynamically changing a mode of advertising, comprising:

transmitting advertisements from an access control according to a nominal mode;

changing the nominal mode in response to an event;

changing to a medium rate between the nominal rate and a fast rate after a time period subsequent to the event, prior to reverting to the nominal rate after a time period subsequent to the event; and

reverting to the medium or nominal rate after comparing a calculation of average power consumption with a threshold.

2. The method as recited in claim 1 , wherein changing the nominal mode in response to the event includes changing the advertisement rate.

3. The method as recited in claim 1 , wherein the event is based on a scan request.

4. The method as recited in claim 1 , wherein changing the nominal mode in response to the event includes changing the nominal mode to a slower mode or a faster mode for a period of time in response to the event.

5. The method as recited in claim 1 , wherein the event is based on a scan request and a comparison between an RSSI value and a threshold value.

6. The method as recited in claim 1 , wherein changing the nominal mode in response to the event includes changing the nominal mode to a slower mode or a faster mode for a predefined period of time.

7. The method as recited in claim 1 , further comprising reverting to the nominal rate after a time period subsequent to the event.

8. The method as recited in claim 1 , further comprising reverting to the nominal rate after an access control unlock event.

9. The method as recited in claim 1 , further comprising reverting to the nominal rate after a low battery event.

10. A method of dynamically changing a mode of advertising, comprising:

transmitting advertisements from an access control according to a nominal mode;

changing the nominal mode in response to an event, wherein the event is based on a scan request and a comparison between an RSSI value and a threshold value;

changing to a medium rate between the nominal rate and a fast rate after a time period subsequent to the event, prior to reverting to the nominal rate after a time period subsequent to the event; and

monitoring an average RSSI values of the scan responses such that the medium mode is switched to if the average RSSI is greater than a minimum value.

11. The method as recited in claim 10 , wherein the event is based on a scan request.

12. The method as recited in claim 10 , wherein changing the nominal mode in response to the event includes changing the nominal mode to a slower mode or a faster mode for a predetermined period of time in response to the event.

13. An access control system, comprising: an access control operable to transmit advertisements at a nominal rate and at least one other rate different than the nominal rate in response to an event;

wherein charging the nominal rate includes changing to a medium rate between the nominal rate and a fast rate after a time period subsequent to the event, prior to reverting to the nominal rate after a time period subsequent to the event; and

reverting to the medium or nominal rate after completing a calculation of average power consumption with a threshold.

14. The system as recited in claim 13 , wherein the rate is selected in response to an event related to an RSSI value.

15. The system as recited in claim 13 , wherein the rate is selected in response to an event based on a scan request.

16. The system as recited in claim 13 , wherein the advertisements using Bluetooth low energy (BTLE) that is receivable by a mobile device.
