Pairing your sensor to your mobile device in the Ruuvi Station app is required for using local Bluetooth sensor alerts and background scanning on iOS devices.
Enable Pair and use background scan to set the Bluetooth connection active.
In order to use background scanning in Ruuvi Station (iOS) you will also need to enable background scanning in App Settings.
Note! Pairing is only possible to one iOS device at a time. Bluetooth alerts will become unreliable if the same sensor was paired to multiple iOS devices in range of your Ruuvi sensor signal. This limitation is due to strict Apple policy related to user privacy.
