3PAIRING Viiiiva
Viiiiva supports communication using both ANT+ and Bluetooth Smart. Some display
units and watches use ANT+ while others use Bluetooth Smart. The pairing procedure
diers slightly between the two options.
3.1 Connecting Viiiiva to the 4iiii App
The 4iiii app is used to update Viiiiva’s rmware, enable and congure advanced
features and otherwise interact with Viiiiva. You can connect to your Viiiiva by scanning
for nearby devices, or using tap-to-pair. After ensuring that your device has Bluetooth
enabled, open the 4iiii app and select “Viiiiva Conguration” from the main menu.
Once you are paired to your Viiiiva in the 4iiii app, you can view your heartrate
by selecting “Workout” from the main menu.
Android: Once you are paired to your Viiiiva in the 4iiii app, you can view your heartrate
by selecting “Sensor Data” from the main menu.
3.2 Scanning for Viiiivas

1. Wake your Viiiiva by moistening the black conductive patches on the strap and
putting it on, or by rubbing the two button snaps on the Viiiiva pod;
2. From the “Viiiiva Conguration” screen in the 4iiii app, tap “Scan for Viiiiva”.
Nearby Viiiivas will appear near the top of the list;
Android: From the Viiiiva screen in the 4iiii app, tap the magnifying glass icon.
Nearby Viiiivas will appear near the top of the list; and

3.5 Pairing Using Bluetooth Smart
Pairing procedures can be dierent between head units and watches, If more details
are required, please consult the head unit/watch manufacturer’s instructions.
Quick Tip: After pairing Viiiiva as a Bluetooth heart rate sensor, many apps will now
display heart rate data along with data from any ANT+ sensors connected to your
Viiiiva without the need to pair those sensors separately. For more information,
refer to Section 4 on ANT+ to Bluetooth Bridging.

6
Viiiiva can be used as an ANT+ to Bluetooth bridge. This feature is useful when you
have a supported ANT+ only sensor that you want to connect to a Bluetooth Smart
bike computer, watch, or smartphone app (such as Zwift). Viiiiva can bridge ANT+
bike speed, bike cadence, bike speed and cadence, bike power, and footpod speed
and cadence data to Bluetooth devices. Use the 4iiii app to connect to your Viiiiva.

3. Wake the ANT+ devices you’d like to
bridge to Bluetooth;
4. Tap “Refresh ANT+ Devices List”;
5. Select your ANT+ sensors from the
displayed list; and
6. Tap “Done”.
Viiiiva will now receive data from the paired ANT+ sensors and retransmit the data
using Bluetooth Smart. You can view this data in the app. You will need to pair
your Bluetooth Smart compatible device to Viiiiva for the device to receive the
data. Please refer to the manufacturer’s instructions for more details on receiving
Bluetooth Smart sensor data from your device or app of choice.

7ACTIVITY LOGGING
Viiiiva has the ability to log heart rate data and data from other connected ANT+
sensors to a .FIT le. This feature allows you to log your activity data without the
need for a separate sports watch or bike computer.
Viiiiva will store one data point every ve seconds. When onboard memory is full,
it will stop saving data until the memory is downloaded or erased. Viiiiva does not
have GPS capability, so the activity les stored by Viiiiva will contain data concerning
heart rate and all connected ANT+ sensors, but no GPS track will be stored.
Quick Tip: The number of hours Viiiiva logs depends on the type of sensors it is
logging data for. If Viiiiva has no paired sensors, it will log 65 hours of heart rate
data. If Viiiiva is paired to a footpod, it will log 22 hours of heart rate, footpod speed
and footpod cadence data, etc.
7.1 Recording Activity Data
With Activity Logging enabled, Viiiiva will start logging sensor data to a .FIT le
when you put it on, and stop recording when you remove the strap. If your Viiiiva is
being used as an ANT+ to BLE bridge, it will automatically stop recording after the
connected ANT+ sensors stop transmitting and/or the strap is removed
(whichever is last).
