Please ensure the device is charged.
Double click the button on the side of the device. If the LED turns BLUE for several seconds, it indicates that the device is not connected and a force start of the Bluetooth advertising/broadcast has been initiated.
Wait for 10-20 seconds to see if the device connects automatically. If not, please follow the steps on the following page.
When you double-click the button on the side of the device and the LED turns WHITE, it indicates that the device is already connected to the app. If a user's app still shows the device as "Disconnected", another Vital Science app on another phone may have added this device and connected to it.
Note: When the user first opens the app, it will always show "Disconnected", and it may take about 10 seconds to establish a connection again. This allows the device to preserve the battery.
What to do when Kairos still won't connect to the phone?
Toggle the phone’s Bluetooth off then back on from the phone’s Settings page.
If that does not help, restart the App. For Android, you must “force stop” the App by going into the phone’s settings page.
If that does not help, try rebooting the phone.
If that does not help, turn Kairos off by pressing the button for 5 seconds until the LED at the top flashes RED. Then, turn the device back on by pressing the button once.
If that does not help, send a message to the Biostrap support team at [email protected]
