I’ve successfully been using a USB ANT+ dongle on a Windows 10 laptop for a a couple of months, connecting to my Garmin HR strap and Garmin Speed/Cadence sensor. This has been working fine up until today when I noticed massive spikes and dropouts on the speed/cadence. When on the pairing screen I noticed it now shows the Garmin Speed Cadence Sensor as a Seiko / Epson sensor. It’s definitely the correct sensor as I can see the speed move with the wheel. The HR monitor is fine.
I’ve spent a while today trying to figure this out and so far have found:
- Garmin HR strap is fine
- the same ANT+ usb stick in another computer with Zwift works correctly with the speed cadence sensor
- Removing/replacing the battery in the Speed Cadence sensor makes no difference
- Uninstalling the USB ANT+ device and drivers makes no difference
- Another identical Garmin speed cadence sensor on a different bike is fine, shown correctly as a Garmin device in the sensors screen
Is there any way in Zwift or Windows to reset the Ant+ devices that have previously been connected? I’m at a bit of a loss as to what to do next.
