How to fix a Bluetooth connection issue on Android?

If your connection status shows a red cross in between the CardioMood and the mobile device as illustrated below, it means that your CardioMood is disconnected from the CardioMood app.

There are many possible causes for a disconnection.

To reconnect, please follow these instructions step by step until your connection is fixed.

  • Bring devices close

    It might be that your CardioMood and your mobile device are too far away from each other, thus unable to communicate. Place your mobile device close to your CardioMood.

  • Enable Bluetooth

    Please check that Bluetooth is turned on on your mobile device settings. It not, please enable it.

  • Give Location permission

    On Android devices, the location is used by the Bluetooth pairing process to locate the devices nearby. Please check that the location permission is on for the CardioMood app on your mobile device settings.

  • Charge your CardioMood battery

    One of the reasons why your CardioMood doesn’t communicate with your mobile device could be that its battery is flat.


Here is how to check if your CardioMood 287-1B is discharged.

Press the pusher on the side of the bracelet. If no LED lights up, the battery is empty. Please charge your CardioMood.

  • Restart your mobile device

    Your connection is still not fixed? Please shut down your mobile device to reset the Bluetooth system. It is important to not select the restart option but completely shut it down. Then, restart your mobile device and open the CardioMood app again.

  • Unpair and pair your CardioMood

    If none of the above could fix your Bluetooth connection, then try to unpair and then re-pair your CardioMood to your mobile device. Please see the related instructions in these articles.
