Setting-up a CORE Account

A CORE account allows you to setup and manage CORE sensors. When you open the CORE app for the first time you will be prompted to log-in or register a new account. 

This is a step-by-step guide for setting up a CORE account.

Adding a CORE sensor

After you have logged-into the CORE app, make sure bluetooth is enabled on the smart phone. 

Check that the CORE sensor is charged and wake it up by shaking it looking for the blinking green light. 

Add a CORE sensor

If the CORE sensor is not identified, place it close the phone and click "Rescan". If the CORE sensor is already owned by someone else, it can't be added to your account unless the original owner first removes it. 

CORE App in Overview

The CORE App has four main sections:

Overview Page - Provides an overview of CORE sensors owned or shared with your account

Sensor Page - For a selected CORE this shows real-time data (when connected) and access to historical data, histogram, Heat Strain Index, Heart Rate, Heat Load, Workout Load and Skin Temperature. Click on a graph to see an expanded graph.

Stats Page - For the selected CORE this page shows weekly, monthly and yearly statistics, Trends, Heat Strain Score and Thermal Load. 

Diary Page - This is calendar overview of allowing specific days with recorded data to be easily selected. 

In addition there are settings pages:

Troubleshooting

CORE Sensor not found

• Checking that bluetooth is enabled / on on your smart phone
• Check that the CORE sensor is charged (min 15 minutes)
• Shake the CORE sensor and look for the blinking green lights
• Move the CORE sensor close to the phone
• Move the CORE sensor further away from the phone (some phones can struggle when the bluetooth signal is too strong / close).

Too many CORE sensors

• Check the Bluetooth serial number on the back of the CORE sensor to identify the correct one (and when connected, give the CORE sensor a unique name).

Bluetooth issues

• Turn bluetooth on / off
• Turn your smart phone on / off
• Move to a different location to escape electromagnetic interference / too many bluetooth signals.
• Move the CORE sensor close to the phone
• Move the CORE sensor further away from the phone (some phones can struggle when the bluetooth signal is too strong / close).

Internet connection issues


The CORE App requires an internet connection to log into your account and to then connect and synchronise with your CORE sensor. Usually the App will display a message if there is no internet connection. 

For a connection with a paired sports device, an internet connection is not required - the CORE sensor connects directly and the CORE App / smart phone is not needed.

Smartphone / App issue


If the smart phone or CORE App is stuck or freezes, quite the CORE App. On many phones when an App is closed, it remains open in the background and needs to be fully quit and then restarted.

Resetting the CORE sensor

In some circumstances, a reset is required.
