What is an ANT+ dongle? Where can I get one?

There are two wireless protocols Zwift supports for sensors connecting with Zwift: ANT+ and Bluetooth Low Energy (BLE). While Zwift is compatible with built-in BLE for most Mac and iOS devices, if your sensor transmits via ANT+, you will need an ANT+ receiver for your device to read that signal.

For a computer, a USB ANT+ dongle is what receives the signals from the sensors on your bike or your trainer and transmits them to Zwift. For iOS, the process is slightly different, and we'll cover this in the second section below.

PC/Mac ANT+ Dongle

Getting an ANT+ dongle for PC or Mac is easy. Head on over to the Zwift Shop to pick up a handy starter pack! Any USB2 ANT+ dongle will work. We recommend the USB-m as it has proven to have the best signal reception in the lab. Make sure you pick up a USB extension cable to get the dongle closer to your equipment and prevent dropouts.

iOS ANT+ Bridge

Zwift includes partial support for ANT+ on iOS, the exception being that you cannot get controlled resistance from a smart trainer. If you're planning on using ANT+ on iOS, you have a few different options to bridge the signal:

Refer to these manufacturers' individual instructions on how to bridge ANT+ sensors using their devices.

Reminder! Resistance control for smart trainers isn't supported over ANT+ on iOS.
