Poor signal quality of performance data can lead to a data dropouts during a workout with a Spivi system.
Data dropouts can be identified by the following symptoms:
- Avatars disappear and re-appear on screen regardless of actual activity.
- Data entries such as leaderboard attributes or color coded values appear as blank values regardless of actual activity.
The overall signal quality is determined by the reception quality, transmission quality and interference sources.
Signal Reception Quality
This is the ability of the system to receive signals from the tracking devices.
It is mainly affected by the location of the receiving devices and the existence of metal obstacles in the workout space.
Signal Transmission Quality
This is the ability of the transmitter device (HR Monitor, Power Sensor, Bike Console etc) to transmit the tracked data in a reliable and effective way. It is mainly affected by the battery condition of the the device and the overall condition of its internals.
Signal Interference Source
This is usually a device that uses the 2.4GHz wireless spectrum to communicate with other devices and can potentially harm the overall signal quality. A common example of such case is a smartphone connected via Bluetooth to the sound system in the room, which may result in poor signal quality.
Optimize Signal Reception Quality
- Check the Wireless Receiver location. It should be placed on the ceiling in the center of the studio with a clear line of sight to the training area. Please follow the Wireless Receiver Installation Guide.
- Make sure that your Wireless Receiver is functioning properly. In case it doesn’t you’ll see an error message on the bottom left corner of the screen.
- WASP Error on the bottom left corner of the means that Spivi system can’t communicate properly with the unit resulting in poor reception quality. Please follow the WASP Error Troubleshooting Guide to resolve this error.
- CUBOError on the bottom left corner of the means that Spivi system can’t communicate properly with the unit resulting in poor reception quality. Please follow the CUBO Error Troubleshooting Guide to resolve this error.
- If your system is configured for Keiser M3i make sure that the BLE dongle is connected properly to the front USB port of the Spivi system and it has a clear line of sight to all bikes in the room. If you still experience signal reception issues you can use a USB extender cable to place the BLE dongle in a higher position in order to improve the reception quality.
Optimize Signal Transmission Quality
- Perform a basic transmitter device operation test. Make sure the device is turned on and active.
- Check the battery status of the transmitter device and replace if it is in a low state.
- If the transmitter device has a monitor/console or it can be connected to an external display (I.E fitness watch, mobile app) make sure real-time data is displayed.
- Heart Rate monitor: Spivi supports any ANT+ compatible monitor and the Polar H7, H10, OH1 and Polar Verity Sense Optical Heart Rate Sensor straps. The heart rate monitor should be turned on and placed correctly in order to detect heartbeats and transmit heart rate data to the Spivi system. Follow the How to wear Heart Rate Monitor Guide to get best results from heart rate monitors.
- Magnet Based Cadence Sensor: The magnet-based cadence sensor computes revolutions per minute by tracking a magnet placed on the bike’s frame. Make sure that the magnet is placed on the bike’s frame and that the sensor is able to track it each time the crank arm passes by it. Press on the rubber button to determine the battery status of the sensors. If you see a green led each time the sensors passes the magnet on the first 10 revolutions then the battery is OK. In case you don’t see a green led on the sensor when you press the button you should replace its battery.
- Magnetless Cadence Sensor: The magnet-less cadence sensor computes revolutions per minute by using an internal accelerometer. In order to activate this sensor one should pedal backward a few times and then forward.
Identify and Disable Sources of Interference
The following items can cause wireless interference over the 2.4GHz spectrum used by the transmitting devices.
Make sure to identify these and use them in a wired configuration instead of the wireless configuration if possible, or move them away from the workout space.
- Smartphone playing music over Bluetooth sound system.
- Wireless speakers.
- Wirelss lighting systems.
- Wirelss video transmitters.
- Wirelss cordless telephones.
- Power sources such main power cabint or external main power lines.
