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.
