  • 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]
