Abstract

Embodiments relate generally to systems and methods for establishing a wireless connection between a gas detector and a mobile device. A method may comprise monitoring, by one of the gas detector and/or mobile device, for a peer device within a first communication range, wherein the peer device comprises the second of the gas detector and/or mobile device; detecting, by one of the gas detector and/or mobile device, a peer device within the first communication range; establishing a first wireless connection with the detected peer device; sending, by the gas detector to the mobile device, connection data for a second wireless connection, wherein the connection data comprises an identifier and a secure PIN; receiving, by the mobile device, the connection data; selecting, by the mobile device, the gas detector using the identifier; and establishing the second wireless connection with the gas detector using the secure PIN.

First claim

What is claimed is:

1 . A method for establishing a wireless connection between a gas detector and a mobile device, the method comprising:
monitoring, by one of the gas detector and/or mobile device, for a peer device within a first communication range, wherein the peer device comprises the second of the gas detector and/or mobile device; detecting, by one of the gas detector and/or mobile device, a peer device within the first communication range; establishing by one of the gas detector and/or mobile device, a first wireless connection within the first communication range with the detected peer device; sending, by the gas detector to the mobile device via the first wireless connection, connection data for a second wireless connection, wherein the connection data comprises an identifier and a secure PIN; receiving, by the mobile device, the connection data; selecting, by the mobile device, the gas detector using the identifier; and establishing the second wireless connection with the gas detector using the secure PIN, wherein the first communication range is smaller than the second communication range.

2 . The method of claim 1 , further comprising communicating gas detection data via the second wireless connection while the gas detector is within a second communication range of the mobile device.

3 . The method of claim 1 , wherein the first wireless connection comprises a near-field communication (NFC) connection.

4 . The method of claim 1 , wherein the second wireless connection comprises a Bluetooth connection.

5 . The method of claim 1 , wherein the gas detector is selected using the identifier from a list of available devices.

6 . The method of claim 1 , wherein selecting the gas detector and establishing the second wireless connection occurs automatically once the connection data is received by the mobile device.

7 . The method of claim 1 , selecting the gas detector and establishing the second wireless connection occurs without input from a user.

8 . The method of claim 1 , further comprising receiving a confirmation input from the user before establishing the second wireless connection.

9 . The method of claim 1 , wherein the gas detector is configured to detect hazardous gases in the environment of the user.

10 . The method of claim 1 , wherein the gas detector and mobile device are configured to be employed in a potentially hazardous work environment.

11 . A communication system comprising:
a gas detector configured to detect one or more hazardous gasses, comprising a memory, a processor, a first communication module, and a second communication module; and a mobile device comprising a memory, a processor, a first communication module, and a second communication module, and configured to:
detect that the gas detector is within a first communication range of the first communication module of the mobile device;
establish a first wireless connection, via the first communication module, with the detected gas detector;
receive connection data for a second wireless connection, wherein the connection data comprises an identifier and a secure PIN;
select the gas detector using the identifier; and
establish the second wireless connection with the gas detector using the secure PIN.

12 . The communication system of claim 11 , wherein the first wireless connection is established between the first communication module of the gas detector and the first communication module of the mobile device.

13 . The communication system of claim 11 , wherein the second wireless connection is established between the second communication module of the gas detector and the second communication module of the mobile device.

14 . The communication system of claim 11 , wherein the first wireless connection comprises a near-field communication (NFC) connection, and wherein the second wireless connection comprises a Bluetooth connection.

15 . The communication system of claim 11 , wherein the first communication module of the gas detector and the first communication module of the mobile device communicate within the first communication range, and wherein the second communication module of the gas detector and the second communication module of the mobile device communicate within a second communication range.

16 . A method for establishing a Bluetooth connection between a gas detector and a mobile device, wherein the gas detector is configured to be used in a potentially hazardous work environment, the method comprising:
monitoring, by the mobile device, for a gas detector within a first communication range; detecting, by the mobile device, a gas detector within the first communication range; establishing a near field communication connection between the mobile device and the gas detector; sending, by the gas detector to the mobile device, connection data for a Bluetooth connection, wherein the connection data comprises an identifier and a secure PIN; receiving, by the mobile device, the connection data; selecting, by the mobile device, the gas detector using the identifier; and establishing the Bluetooth connection with the gas detector using the secure PIN.

17 . The method of claim 16 , further comprising communicating gas detection data via the second wireless connection while the gas detector is within a second communication range of the mobile device.

18 . The method of claim 16 , wherein selecting the gas detector and establishing the Bluetooth connection occurs automatically once the connection data is received by the mobile device.

19 . The method of claim 16 , wherein the gas detector is configured to detect hazardous gases in the environment of the user.

20 . The method of claim 16 , wherein the gas detector and mobile device are configured to be employed in a potentially hazardous work environment.
