Abstract

A method and system for communicating with wireless messaging enabled door locks is disclosed. The method includes advertising availability of the door lock via wireless messaging for a first period of time; triggering a message send event; determining a destination node; connecting to the destination node via Bluetooth; sending the message to the destination node; and entering a low power state for a second period of time, wherein the second period of time is longer than the first period of time; wherein the destination node is chosen from a second door lock or a computing system.

Claims (71)

1. A method for communicating with wireless messaging enabled door locks comprising:

advertising availability of a first door lock via wireless messaging for a first period of time;

triggering a message send event;

determining a destination node;

connecting to the destination node via wireless messaging;

sending a message to the destination node; and

entering a low power state for a second period of time, wherein the second period of time is longer than the first period of time;

wherein the destination node is a second door lock;

wherein the message is a message bundle including a first message including a portion identifying a sending peripheral that sent the first message to the first door lock and information and a second message from the first door lock including a portion identifying the first door lock and information.

2. The method of claim 1 wherein:

determining a destination node further comprises:

examining a routing table to determine the destination node; and

searching for a second advertisement signal from the destination node.

3. The method of claim 2 wherein:

examining a routing table comprises determining a primary destination node and a secondary destination node using the message; and

searching for the destination node advertisement comprises first searching for the primary destination node advertisement and subsequently searching for the secondary destination node advertisement.

4. The method of claim 3 wherein:

determining the destination node comprises determining a direction of the communication.

5. The method of claim 3 further comprising:

determining that the message includes broadcast information; and

sending the information to both the primary destination node and the secondary destination node.

6. The method of claim 3 further comprising:

determining that the message includes broadcast information;

examining the routing table to determine a destination for broadcast information; and

sending the information to the destination for broadcast information.

7. The method of claim 1 wherein triggering the message send event comprises receiving a message.

8. The method of claim 1 wherein:

sending the message to the destination node comprise;

determining whether the message is an exception message or a non-exception message;

when the message is a non-exception message, waiting a period of time prior to sending the non-exception message;

when the message is an exception message, sending the exception message immediately.

9. The method of claim 1 wherein:

triggering the message send event comprises expiration of an audit timer.

10. The method of claim 9 wherein:

data sent after expiration of the audit timer includes: battery status, diagnostic information, entry events, and room temperature.

11. A system of door locks forming a mesh network comprising:

a central computing device;

a plurality of door locks with wireless messaging capability, a first door lock of the plurality of door locks configured to:

advertise availability of the first door lock via wireless messaging for a first period of time;

trigger a message send event;

determine a destination node, wherein the destination node includes a second door lock of the plurality of door locks;

connect to the destination node via wireless messaging;

send a message to the destination node; and

enter a low power state for a second period of time, wherein the second period of time is longer than the first period of time;

wherein the message is a message bundle including a first message including a portion identifying a sending peripheral that sent the first message to the first door lock and information and a second message from the first door lock including a portion identifying the first door lock and information.

12. The system of claim 11 wherein the first door lock is further configured to:

repeat the advertising after expiration of the second period of time.

13. The system of claim 11 wherein:

triggering the message send event comprises determining existence of an exception event.

14. The system of claim 13 wherein:

the exception event comprises one or more of the following: unauthorized entry, attempted unauthorized entry, credential change, a locking plan change, and a door lock being in an open position for greater than a threshold amount of time.

15. The system of claim 14 wherein:

a credential change comprises one or more of the following:

an authorization of a key card;

a de-authorization of a key card;

an authorization of a wireless messaging enabled mobile electronic device; and

a de-authorization of a wireless messaging enabled mobile electronic device.

16. The system of claim 11 wherein:

triggering the message send event comprises expiration of an audit timer; and wherein:

data sent after expiration of the audit timer includes: battery status, diagnostic information, entry events, and room temperature.

17. The system of claim 11 wherein:

triggering the message send event comprises determining the door lock has information to be transmitted.

18. The system of claim 17 wherein:

determining the door lock has information to be transmitted comprises determining existence of an exception.

19. The system of claim 11 wherein:

determining a destination node comprises scanning for a second advertisement signal from a nearby second door lock.

20. The system of claim 11 wherein:

sending the message to the destination node comprise;

determining whether the message is an exception message or a non-exception message;

when the message is a non-exception message, waiting a period of time prior to sending the non-exception message;

when the message is an exception message, sending the exception message immediately.
