Onelap supports a ton of hardware, with some broadcasting in Bluetooth Low Energy (BLE); ANT+; or both. Although they both work in a similar manner, BLE tends to give you a stronger signal. With the more modern ANT+ and BLE protocols (typically found in newer hardware), you tend to get a more accurate Onelap experience. See trainers, power meters, heart rate sensors, bikes, and speed and/or cadence sensors for specific devices supported.
