Connect an Eko Device with the Eko App

Bluetooth is used to connect your Eko device to the Eko App. This is how data is sent from the Eko device to the app. If the two aren’t paired or they have a poor Bluetooth connection, the app won’t receive data.

The first time you use the Eko device with the Eko App, the app guides you through setting up the Bluetooth connection with the app. After the first time, the app automatically connects to the most recently connected Eko device when:

  • The Eko App is on (either active on your screen or running in the background)
  • The Eko device is turned on and within range.

    You will then be prompted to pair via Bluetooth on your mobile device screen, and confirm on your Eko device screen (CORE 500 only)

  5. Once connected, you'll be able to start a New Encounter.

Note: Some screens may appear different depending on your mobile device's operating system.

Reconnecting to the Eko App

Once you have connected your device to the Eko App, it will reconnect automatically with the most recently connected device. If you use multiple Eko devices across a single mobile device and Eko Account, you will need to reconnect manually each time.

Tips for Bluetooth connection

Reduce distance

Make sure there aren’t objects such as walls, furniture, or people between the Eko device and your mobile device. Tips to improve Bluetooth connection:

  • Reduce the distance between the Eko device and your mobile device.
  • Allow a line of sight between the Eko device and your mobile device.

Lost connection

You’ll lose Bluetooth connection if you force close the Eko App or turn off the Eko device. On the CORE 500™, the Bluetooth icon has a red slash through it when it's no longer connected. On the CORE™ or DUO™, the LED light blinks white when it’s no longer connected.

To regain connection:

  • Turn on the Eko device.
  • Open the Eko App and re-pair the Eko device.

Reduce interference

To reduce the risk of device interference:

  • To reduce the risk of device interference, keep the Eko device at least 6 feet away from radio frequency (RF) emitters, such as Wi-Fi routers, mobile and cordless phones, medical scanners, radar systems, microwave ovens, and so on.
