The hardest part of setting up my Wahoo KICKR with Zwift was pairing it with my computer. The KICKR can pair with the computer using both Bluetooth and ANT+. Initially, I choose to use ANT+ because my Garmin cadence sensor and heart rate monitor were ANT+. Since most laptops aren’t ANT+ capable, I had to use a USB ANT+ dongle. Luckly, I already had a Garmin USB ANT+ dongle that I could use.
Even if your computer isn’t ANT+ or Bluetooth capable, generic USB ANT+ and Bluetooth dongles are cheap and relatively easy to find so your computer can still be used for Zwift. In my case when I later switched to Bluetooth my computer’s Bluetooth was not compatible with my KICKR, so I had to use a Bluetooth dongle. Regardless of which protocol you use, the setup is basically the same.
Nevertheless, if you still find pairing difficult, another alternative is to use the Zwift Companion app on a mobile device as a bridge that can convert the trainer’s Bluetooth signal into a format that your computer can recognize.
Over the past few years, I have paid my devices with ANT+, Bluetooth and the Zwift Companion app. All three methods have worked for me. Once everything is paired you are ready to go.
