Abstract

A system and method for gathering data from Bluetooth devices. The system connects to two or more Bluetooth client devices and assigns the Bluetooth client devices to different Bluetooth channels. Information is then downloaded from the connected Bluetooth client devices that meet a first set of one or more criteria.

Claims

1. A system comprising:

a processor;

a plurality of dongles, each of the plurality of dongles being communicatively coupled to the processor;

a non-transitory computer-readable medium communicatively coupled to the processor, the non-transitory computer readable medium storing instructions that, when executed by the processor, cause the processor to;

direct a first dongle to scan for client devices available to connect using a Bluetooth protocol;

if the first dongle detects a first client device available to connect, determine whether a unique identifier of the first client device is present in a list of one or more unique identifiers;

if the unique identifier of the first client device is present in the list of one or more unique identifiers;

connect a second dongle to the first client device on a first channel;

direct the first dongle to scan for client devices available to connect using the Bluetooth protocol; and

determine a first amount of elapsed time since a most recent instance of the system downloading information from the first client device;

if the first amount of elapsed time is greater than a first threshold, download data from the first client device on the first channel using the second dongle;

if the first dongle detects a second client device available to connect, determine whether a unique identifier of the second client device is present in the list of one or more unique identifiers;

if the unique identifier of the second client device is present in the list of one or more unique identifiers;

direct a third dongle to connect to the second client device on a second channel;

direct the first dongle to scan for client devices available to connect using the Bluetooth protocol; and

determine a second amount of elapsed time since the system most recently downloaded information from the second client device;

if the second amount of elapsed time is greater than the first threshold, determine whether the second dongle is occupied; and

if the second dongle is occupied, download data from the second client device using the third dongle.

2. The system of claim 1 in which, within an instance of the processor executing the instructions:

the first dongle does not download data from a client device; and

neither the second dongle nor the third dongle scan for client devices available to connect using the Bluetooth protocol.

3. The system of claim 1 in which, if the second dongle is occupied, the second dongle is occupied downloading data from the first client device.

4. The system of claim 1 in which:

the processor connects the second dongle to the first client device only if the first client device is of an approved device type and

the processor directs the third dongle to connect to the second client device only if the second client device is of the approved device type.

5. The system of claim 1 in which the instructions cause the processor to:

download data from the first client device only if;

the first client device is of a specified device type;

or

the first client device presents a user identifier present on a list of user identifiers; and

download data from the second client device only if;

the second client device is of the specified device type;

or

the second client device presents a user identifier present on the list of user identifiers.

6. The system of claim 1 in which the instructions cause the processor to:

introduce delays between transmission slots on the first channel when downloading data from the first client device;

or

introduce delays between transmission slots on the second channel when downloading data from the second client device.

7. The system of claim 6 in which the delays between transmission slots of at least one of the first channel or the second channel are random.

8. The system of claim 1 in which the system synchronizes frequency hopping of the first channel with frequency hopping of the second channel.

9. The system of claim 1 in which the first dongle sends contact information for the first client device to the second dongle before the second dongle connects to the first client device.

10. The system of claim 1 in which the system simultaneously downloads data from the first client device and the second client device.

11. The system of claim 10 in which the first client device and the second client device are one and the same.

12. The system of claim 1 in which:

the system downloads data from the first client device and a third client device on the first channel using time division multiplexing or

the system downloads data from the second client device and a fourth client device on the second channel using time division multiplexing.

13. The system of claim 1 in which:

after downloading data from the first client device, the system issues a command to the first client device causing the first client device to cease transmitting radio signals for a specified amount of time;

or

after downloading data from the second client device, the system issues a command to the second client device causing the second client device to cease transmitting radio signals for a specified amount of time.

14. The system of claim 1 in which the system assigns a first number to the first client device, assigns a second number to the second client device, and connects to the respective client devices in order of the respective number assigned to each device.

15. A system comprising:

a processor;

a plurality of dongles, each of the plurality of dongles being communicatively coupled to the processor;

a non-transitory computer-readable medium communicatively coupled to the processor, the non-transitory computer readable medium storing instructions that, when executed by the processor, cause the processor to;

direct a first dongle to scan for client devices available to connect using a Bluetooth protocol;

if the first dongle detects a first client device available to connect, determine whether a unique identifier of the first client device is present in a list of one or more unique identifiers; and

if the unique identifier of the first client device is present in the list of one or more unique identifiers;

direct a second dongle to scan for client devices available to connect using the Bluetooth protocol;

connect the first dongle to the first client device on a first channel; and

determine a first amount of elapsed time since a most recent instance of the system downloading information from the first client device;

if the first amount of elapsed time is greater than a first threshold, download data from the first client device on the first channel using the first dongle;

if the second dongle detects a second client device available to connect, determine whether a unique identifier of the second client device is present in the list of one or more unique identifiers;

if the unique identifier of the second client device is present in the list of one or more unique identifiers;

connect the second dongle to the second client device on a second channel; and

determine a second amount of elapsed time since the system most recently downloaded information from the second client device; and

if the second amount of elapsed time is greater than the first threshold, download data from the second client device using the second dongle.

16. The system of claim 15 in which, if the unique identifier of the second client device is present in the list of one or more unique identifiers, the instructions direct the processor to:

direct the first dongle to scan for client devices available to connect using the Bluetooth protocol if the first dongle is not occupied;

direct a third dongle to scan for client devices available to connect using the Bluetooth protocol if there is a third dongle that is not occupied;

or

direct the first dongle to scan for client devices available to connect using the Bluetooth protocol when the first dongle is no longer occupied if the first dongle is occupied and there is no third dongle.

17. The system of claim 15 in which the system simultaneously downloads data from the first client device and the second client device.

or

introduce delays between transmission slots on the second channel when downloading data from the second client device.

22. The system of claim 21 in which the delays between transmission slots of at least one of the first channel or the second channel are random.
