Device Overview

When launched, the tool automatically scans for all devices within the BLE dongle’s range.

Detected devices appear in the main window. Calera® research devices are labeled as "CAL" and CORE devices as "CORE."
The top section displays all devices in range, including their status and unique Bluetooth and ANT+ IDs.
The bottom section provides a log of each device’s activity.

Utilities

Set State

Set the Device State (Picture 1)

Calera® devices operate in several states. The current state is displayed in the Device Overview window at the top.

To update the state, select your desired mode and click “Set State”:

Logging: Enables "logging" mode to capture raw data at a 1 Hz frequency.
Measuring: Standard state of the device. Note that data collected in measuring mode cannot be exported from the PC tool. You should use logging mode for this.
Download Ready: Ends logging and prepares the device for data download. After download, the device automatically returns to "measuring" mode.
Ready: Do not use
Shipping: Do not use unless storing the device for long periods. This puts the device into hibernation. The device can only be reactivated by charging (not shaking).
Factory Reset: Avoid using as this will erase all data and settings on the sensor.

After changing the device state, always click "Scan devices" to refresh the device list and confirm the new status.

Get Device Info

Select a device, then click "Get device info" and expand the entry using the plus (+) sign in the Update log at the bottom. (Picture 2)

You will see:

Current readings for Tskin, Tcore, HR (when paired) and heat-flux (encrypted)
ANT+ ID number
Firmware version
Precise battery status
Permission level
Storage details
Algorithm mode
Additional device settings
Subject information: ID, age, weight, height, gender, and device position

Set subject info

Enter Subject ID, age, weight, height, gender, position of device. (Picture 3)
This information will appear at the top of the exported CSV file

Discover HRM & Pair HRM

To Pair an HRM to your Calera device do the following (Picture 4)

Select your device, click "Discover HRM," and wait for the scan to complete (indicated by the green bar at the bottom, about 10 seconds).
The ANT+ and Bluetooth IDs of detected HRMs will appear.
Note the ANT+ or BLE ID, as this information will disappear when you leave the page.
Then click the "Pair HRM" and enter its ANT+ ID or BLE address/name (example: ANT+ “64001”).
Avoid pairing multiple HRMs with a single Calera device.
Each HRM only needs to be paired once with each device. The pairing will be retained for future use.

⚠️ Calera® supports most ANT+ and BLE heart rate monitors. You can choose between the ANT+ and BLE channel.

Algorithm mode

The four algorithm modes (Picture 5) :

Always Low Activity: Designed for low-intensity situations such as sleep monitoring, circadian rhythm studies, or everyday use.
Always High Activity: Best suited for prolonged physical activity, such as sports or manual labor.
Switch upon HR Threshold: Automatically switches from Low to High Activity Mode when the heart rate exceeds 120 bpm.
Switch upon HR Availability: Uses High Activity Mode only when heart rate data is available. As soon as it detects a heart rate signal (even during sleep), it switches from Low to High Activity Mode.

⚠️ Please refer to our flow chart to choose the right algorithm for you or contact info@caleraresearch.com
As a standard, we recommend using always low activity for sleep/circadian rhythm studies and always high activity for sports science/occupational health studies.

Advanced settings

Standby mode: set the device to go into "standby" mode when it detects no skin contact for over 10 minutes
Temperatures via ANT Moxy profile: special feature to enable recording of core temperature with Wahoo devices (Picture 6)

Other Tabs

Download (Picture 1)

1. After logging mode, set your device to ‘download ready’ mode (Set state → Download ready).

2. Select the device you wish to download data from.

3. Choose where to save your file (‘Browse’).

4. Click ‘Download’ and wait for the process to finish (‘Download complete’).

Data will be downloaded one device at a time and saved to your chosen location. If you are using multiple dongles, you can download from several devices simultaneously.

Update (Picture 2)

Select the device you want to update, then click ‘Update devices.’

Keep the FW Channel set to ‘current’ and the FW Version on ‘latest’ unless otherwise directed by the CALERA team or prompted by a notification.

You can monitor the progress of the update in the update log

Cloud (Picture 3)

Access cloud-based historical data at one-minute resolution. To view your data, please create an account and register your sensor(s) to your profile.

Device Groups (Picture 4)

To create a group: Hold the CTRL key and select the desired devices. Enter a group name in the text box and click ‘Save.’
Groups are stored locally on your computer and remain available until you delete them. You can create multiple groups, each containing one or more devices.

To select a group: Click the arrow to expand your saved groups, select a group name, and click ‘Load.’

Note: Devices must first appear in the scan list. Groups only reference devices that have been scanned and displayed.

Save: Store a new group of devices

Load: Highlight devices from a saved group

Delete: Remove a group from your list

Once your devices are grouped, you can quickly highlight all devices in that group by selecting the group name and clicking ‘Load.’ This allows you to efficiently manage recording states (e.g., start or stop) across all devices in the group simultaneously.
