ANT+ vs BLE Interference Troubleshooting Guide – Spivi

If you experience an issue with your performance data dropping to zero or spiking, it is possible that you are experiencing signal interference because Spivi is not receiving all of your ANT+/BLE data packets.

Now just before we begin, please be sure you have tried the following:

Disconnect your ANT+/BLE dongle from your device, then reconnect it.
Restart Spivi, and unpair/pair your fitness equipment.
Close any apps that might be paired to your sensor.

Below you will find the most common causes of interference, and possible solutions:

Physical distance: Your ANT+/BLE dongles have a limited distance in which they are able to operate without signal loss.

Move your fitness equipment closer to the ANT+/BLE dongle.
A USB extension cable can also be used to position your dongles closer to your fitness equipment.

Physical barriers: Any object or wall that blocks line of sight from your fitness equipment’s sensors to your ANT+/BLE dongles can cause signal loss.

Try to position your ANT+/BLE dongles in such a way that there are no physical objects/walls that block line of sight with your fitness equipment.

Wireless signal interference: Some devices transmit wireless signals or electromagnetic fields that can cause wireless signal interference.

Position your ANT+/BLE dongles far away from devices that transmit wireless signals or electromagnetic fields
Some examples of devices that transmit wireless signals or electromagnetic fields include:
• Bluetooth headphones, speakers, or hearing aids

• WiFi router

• Microwaves

• Fans

• Direct Satellite Services

• Cordless telephones

• Wireless video transmitters (Chromecast, AirPlay, Fire TV Stick, etc.)

• Wireless speakers

• Unshielded cables

• Any devices that use a cable to connect to a computer or power source

• Any devices that transmit a wireless signal

Low sensor battery: Some fitness equipment’s sensors require batteries to operate.

If your device requires batteries, try replacing the batteries with fresh ones.

Dysfunctional sensor: If the above troubleshooting steps did not fix the issue, you may need to replace your ANT+/BLE dongles.

Make sure your fitness sensor is functional.
• For a Bluetooth sensor, open your Bluetooth settings and search for Bluetooth devices. If your sensor doesn’t appear, there’s an issue with the sensor or it’s paired to something else.

• For an ANT+ sensor, open any 3rd party app that can read ANT+ sensor data, and pair your sensor. If your sensor doesn’t appear, there’s an issue with the sensor.

Unavailable dongle: Your ANT+/BLE dongles can only be used by one software at a time.

Exit any other software besides Spivi that may be hijacking your ANT+/BLE dongle.
Disconnect and reconnect your ANT+/BLE dongle and restart the Spivi software.

Loose dongle: It’s possible that your ANT+/BLE dongles are not securely connected to the USB port.

Disconnect and reconnect your ANT+/BLE dongles.
Make sure your ANT+ dongle is firmly plugged in.

Insufficient dongle power: Although ANT+ dongles work best with 500mA of current, some USB ports only supply 100mA.

Try switching your ANT+BLE dongles to a different USB port, or use a powered USB hub.

Dysfunctional dongle: If the above troubleshooting steps did not fix the issue, you may need to replace your ANT+/BLE dongles.

If after replacing your dongles you still experience issues, you may need to contact your fitness equipment manufacturer, as its likely that your fitness equipment’s sensors may be the cause.
