Hi. I got all excited when I noticed that the latest Zwift 1.0.16361 mentioned Wahoo ANT+ dongle compatibility.
I downloaded the app on my iPhone 5s and borrowed a friends Lightening to 30 pin adapter and Wahoo ANT+ dongle. Unfortunately the ANT+ symbol didn’t show up on the Paired Devices screen, only the Bluetooth icon shows. I connected the dongles before and after restarting the app. The Wahoo ANT+ dongle does work but it is a few years old.
Hrm, we are seeing plenty of ANT dongle usage in the latest version of Zwift.
Two things to check:
Do you have a case on your phone that could keep the adapter from plugging all the way in?
Are you sure the adapter is a genuine apple adapter? Some knockoffs (and there are many) just have the pins for charging or audio, but not all the data channels.
