Abstract

Methods, systems and devices for broadcasting messages of different packet formats in interleaving fashions, wherein a transmitter may broadcast a first packet in a first format configured to be well-suited for a first software implementation of a receiver and broadcast a second packet in a second format that is associated with a second software implementation (e.g., firmware, application, etc.). The receiver may receive and process the first packet to detect information that indicates the presence of messages of the second packet type, adjust the receiver (i.e., change a behavior of the second software implementation) in response to detecting information, receive and process the second packet via the second software implementation, and perform an action based on the processed second packet. In some embodiments, the first and/or second messages may include portions of data that may be combined by the receiver.

adjusting the receiver to process the one or more messages of the second packet format based on the detected information;

receiving, by the receiver in response to adjusting the receiver, a second message of the second packet format transmitted by a beacon; and

performing, by the receiver, an action based on the received second message.

5. The method of claim 4, wherein the second beacon is a mobile device.

6. The method of claim 1, wherein adjusting the receiver to process the one or more messages of the second packet format based on the detected information comprises at least one of:

waking, by the receiver, a software implementation associated with the one or more messages of the second packet format based on the detected information; and

changing, by the receiver, a duty cycle for the software implementation associated with the one or more messages of the second packet format to increase a frequency at which the software implementation monitors for receipt of the one or more messages of the second packet format at the receiver.

7. The method of claim 1, wherein performing, by the receiver, the action based on the received second message comprises transmitting, by the receiver, to a server a sighting message including data from the received second message.

8. The method of claim 1, further comprising:

identifying, by the receiver, a first portion of data by processing the received first message; and

identifying, by the receiver, a second portion of the data by processing the received second message,

wherein performing, by the receiver, the action based on the received second message comprises;

combining, by the receiver, the identified first portion of the data and the identified second portion of the data;

generating, by the receiver, a command based on a combination of the identified first portion of the data and the identified second portion of the data; and

executing the command by the receiver.

9. The method of claim 1, wherein the first message and the second message are non-connectable Bluetooth packets.

10. The method of claim 1, wherein:

the first message either includes a first universal unique identifier with a first length of zero or does not include a Bluetooth SIG specified universal unique identifier; and

the second message includes a second universal unique identifier with a second length that is not zero.

11. The method of claim 1, wherein the second packet format permits more data to be transmitted in the one or more messages of the second packet format than in the first message.

12. The method of claim 1, wherein the second packet format utilizes a stronger security protocol.

13. The method of claim 1, wherein the receiver is included in a mobile device.

14. The method of claim 1, wherein the beacon is included in a mobile device.
