Ngauge 4x4 Gateway

Our Gateway is compulsory for iOS/iPhone users under the following conditions:

1. When you intend to use the nGauge 4x4 App while it is minimized (running in the background).

2. If you already have a Battery Voltage Sensor, Gas Liquid Level Sensor, or plan to purchase one.

If you plan to keep the nGauge 4x4 App open at all times (in the foreground) and do not have a Battery Voltage Sensor or Gas Liquid Level Sensor, the Gateway is not necessary.

The Gateway can be easily plugged into a standard USB connector, such as a car radio or a mobile charger, to power it. The nGauge 4x4 App supports the use of multiple Gateways if you switch between multiple vehicles.

Please note: Enabling the mute switch on the side of your iPhone will silence all audible alarms from the app. Notifications will still be displayed but will be silent.

Why does iOS require the Gateway for the nGauge 4x4 App to function while running in the background? When you minimize or run the nGauge 4x4 App in the background, iOS blocks Bluetooth messages from reaching the nGauge 4x4 App because the App is not "paired" with each individual sensor. To avoid this problem, nGauge 4x4 developed the Gateway specifically for Apple/iOS. The App will remain connected or paired with the Gateway, whether the app is running in the foreground or background. The Gateway then acts as a relay, transmitting all Bluetooth messages from the sensors to our app, and you will be instantly alerted by an alarm when an issue occurs.

No manual pairing or setup is required from the user's side. The app will detect the Gateway as soon as it is in range and automatically connect to it to receive information from your sensors. Please note; only one phone can connect to the Gateway at a time.
