Device Dropouts

Sensor Battery

When a device battery gets low, the reception distance decreases. Try replacing the device battery. Some devices report their battery condition over ANT+ and we display that on the Devices page. But it is not a universal feature, and speed/cadence sensors can't report it due to a protocol limitation.

If your head unit picks up the signal, but TrainerRoad does not try moving your bike setup closer to your computer or phone. Sometimes a couple of feet can make a big difference.


Wireless devices such as 2.4 GHz routers, wireless speakers and wireless mice may interfere with the ANT+ and Bluetooth signal. ANT+ and Bluetooth use the 2.4 GHz band. Try moving any other wireless devices a couple of feet away.

If you suspect your router to be interfering, you can change your wireless channel.


Is something blocking the sensor? Try removing any physical obstructions between the sensor and the ANT+/Bluetooth device

Direct Line of Sight

Do your best to ensure that your computer has the most direct line of sight possible to your sensors. Simply put, the closer and more level your devices are to your phone or computer, the better readings you will get.

Computer battery setting

Some PC's have variable battery settings. If your battery is set to "balanced", your computer may not be allocating enough power to the USB ports for the ANT+ stick or built in Bluetooth receiver to work well. Switch your power-management setting to "high performance".

ANT+ Device Dropouts

Here are a few things you can do to alleviate ANT+ device dropouts. Scroll down for help with Bluetooth Dropouts.

Get the ANT+ USB stick closer to your devices

Placing the ANT USB stick closer to your sensors will make the USB stick more likely to pick up an ANT signal. To do this, you can move your computer or iOS device closer to your sensors.

If on a computer, you can also use a USB extension cable to get the USB stick closer to your devices.


Disable Garmin ANT Agent/Express and any other software that can take over the ANT+ USB stick.

Bluetooth Smart (4.0) Dropouts


Other wireless devices such as wireless speakers and keyboards can sometimes cause interference with your BT 4.0 devices. Try turning them off or moving them away from your setup.
