Overview

For Garmin devices there is a CORE Connect-IQ Data Field. It can be downloaded, installed, synchronized and updated using the Garmin Connect-IQ Smartphone Apps.

The CORE ConnectIQ Data Field for Garmin cycling computers and watches allows you to view CORE Heat Zones, time in zones, Heat Strain Index, core body temp, and skin temp directly on your connected device and record your activity data to the FIT file.​

When the CORE sensor is paired (once) it broadcasts data over ANT+ to the paired Garmin devices​. With the newest generation of Garmin devices it is now possible to pair CORE natively, like any other sensor.

CORE Data Field Setup

STEP 1 - Install CORE Data Field

Depending on your Garmin device, you will need the Garmin Connect App and/or the Garmin Connect-IQ App on your smart phone. It is likely that when you have setup your Garmin devices, the apps are already installed.  ​​

A. Open the Garmin Connect-IQ app on your phone. Ensure you are logged in with your Garmin account. Search for "Core Body Temperature" and select the App titled "CORE Body Temperature Monitor Data Field". Select "Install".  ​​Wait for the sync between phone and Garmin device to complete.

B. Repeat this step for each Garmin device on your account if you want to use CORE with them.

NOTE: depending on the age / memory size of your Garmin device, the Connect IQ app store will automatically present you a "legacy" Data Field. Due to memory restrictions, this cannot offer full functionality and will not be subject to further development.

STEP 2 - Pair CORE sensor

You need to set the ANT+ ID manually in the Data Field settings. You can access the settings in the Connect-IQ app or directly on the device level.

You may need to manually assign the CORE Sensor ANT+ ID. This can be found either on the rear of your sensor or in the sensor settings menu of the CORE app.
​
Save the changes and sync your Garmin device once again.​

STEP 3 - Assign Data Fields

Navigate to your device’s settings and select “activities and apps.” This is where you can select the activity type to which you wish to add the CORE data fields.

After selecting the activity type, select “data screens” and “add data screen.”

Select “Custom Data” and the layout type. Now you can add CORE data from the Connect IQ fields menu.

Garmin may automatically select the data type depending on the size of the data field. For example, it will use core or skin temp in the smaller fields and Heat Zones in the larger fields.

The Garmin devices will only display real-time data from the CORE sensor and record this to the FIT file once it is assigned to a Data Field.

​On some Garmin devices this can be assigned via the Garmin Apps and on many Garmin devices the data field is assigned directly via the watch or bike computer. ​

Setup is now complete!

Data Field Settings

CORE Sensor Id - This can usually be left at the default 0 and when you connect to the CORE sensor it will automatically update.​ In the case that there are multiple CORE sensors, to ensure you are connecting the correct CORE sensor to the Garmin, you can manually enter the ANT id number. You can find the ANT ID of the CORE sensor on the rear of the CORE or inside the CORE app:  Settings > ANT+ ID

High Temperature Alert - By default this is 0 and no alerts will be triggered. Set a temperature value (ºC or ºF) and when this is reached and remains for 3 minutes, it will trigger an alert on your Garmin device. If your temperature increases by a further 0.21ºC another alert will be triggered.​​

Low Temperature Alert - By default this is 0 and no alerts will be triggered. Set a temperature value (ºC or ºF) and when this temperature is reached and remains for 3 minutes, it will trigger an alert on your Garmin device. If your temperature decreases by a further another 0.19ºC another alert will be triggered.​​

Display Options - By default this is 0 and this number can be changed to modify the data displayed and also compatibility.

The following options are only relevant when using the "simple" text-only variation of the data field:

• Display Option 0 : The data field display the real-time core body temperature.
• Display Option 1 : The data field alternates between real-time core body temperature and skin temperature.
• Display Option 2 : The data field alternates between real-time core body temperature and Heat Strain Index (HSI).
• Display Option 3 : This combines '1' and '2'. The data field alternates between real-time core body temperature, Skin temperature and Heat Strain Index (HSI).

The following options are required to change between metric and imperial units:

• Display Option 16 : The Connect-IQ only displays in Celcius ºC by default (even when all of your device settings are in ºF). Set the Display Option to '16' so that the connect-IQ data shows temperature data in Fahrenheit ºF. *Note: on some newer devices this option may no longer be required and the data field will automatically display in °F*
• Display Option 17 : This combines '1' and '16'. The onscreen display will alternate between core body temperature and skin temperature and the Connect-IQ the summary will be displayed in Fahrenheit ºF (instead of Celcius).

The following display options may be required if you use CORE alongside other sensors which require a dedicated Connect IQ data field. This includes Stryd Running pods and Tymewear HR belts:

• Display Option 32 : In the case you encounter issues using sensors simultaneously, this setting may resolve problems. This option will not display charts or data in Garmin Connect but data will be recorded in the FIT file. Option 33 combines options 32 & 1, option 34 combine options 32 & 2, etc.
• Display Option 256 : Displays core temperature during activity but does not record in FIT file. This is the last resort option for users who want to have both Core and Stryd data fields active. The Core data will still be visible in the app if you sync your device and phone after working out.

Use Simple Data Field:  You can choose if you want to see the graphical Heat Strain Index Display with the time in zones or the simple text based numbers:

• Default: Show advanced metrics depending on the size of the Data Field available
• In smallest fields: In smallest fields on the screen, always show the simple Data Field
• Always: Always show the simple text-based information

Celcius / Fahrenheit and Units - The units for temperature are based on your Garmin device settings.​ The exception is the summary data inside Garmin Connect-IQ which is always displayed in Celcius. Follow the guide above and use Display Options 16 or 17 to set the Garmin Connect-IQ summary of temperature data in Fahrenheit.

​Garmin Activities

Please be aware, on Garmin devices the procedure for starting an activity may differ, please refer to your Garmin product manual or the Garmin Support page.​

Garmin Setup Troubleshooting

• Most Garmin watches only support installation of two Connect IQ data fields. For newer models this has been increased to four.
• The amount of data channels from Connect IQ fields which can be saved in the FIT file is limited by Garmin. This differs from device to device. If you are using multiple data fields in any given activity profile, the combined total may exceed the permissible limit. In this case an IQ logo will be displayed, indicating the data field has crashed. You will need to remove custom data fields until you fall below the limit.
• If the CORE sensor data does not appear, check that it is charged and on (shake it and look for the green blinks).
• If you change CORE device, remember to update the ANT ID in the data field settings
• Keep your CORE firmware up-to-date! The CORE App will automatically prompt you to update and gives you the benefit of continuing improvements.
• Sometimes after a new install, the data field displays an IQ logo. In this case, restarting the Garmin device can help reset it so it connects. Also check that the Garmin app has synchronised with the device. Check that the ANT+ ID is correct and some Garmin devices may need to be reinstalled
• If nothing else works, a magnet reset of the CORE device can help. (swipe a magnet over lower section on the SKIN side of your CORE until the LED flashes).
