I have a technical background and have put too much effort into making this work reliably with Zwift. I ended up buying a Bluetooth heart rate monitor so I didn't have to use ANT+ and it's been reliable ever since. I didn't realize it until later when I was using another external device to control my speakers at the time * It was random if it found my ANT+ devices at all. This device does not respond to ANT+ commands when running diagnostic tools (open source)* USB ANT+ devices will disconnect after 20 minutes; and my Surface Pro stopped charging.* I found a support email address and someone replied. The firmware update was available when I downloaded the update tool (from the Chinese website) on the Android device. First bought a BT heart rate monitor. or bought a branded version of ANT+ (I think Garmin owns the brand).
