If your Windows PC is hing ANT+ issues, there appear to be two options for installing the driver.
First - Semi-automatic
open “Windows Update” and click “Check for updates”. “View optional updates” and find “Dynastream Innovations, Inc. - Bus Controllers and Ports, Other hardware - ANT USB-m”, then install it.Second - manual
Wahoo Fitness has a page set up describing the process, with screencaps, here: https://support.wahoofitness.com/hc/en-us/articles/360021559679-Installing-ANT-drivers The specific link to download the ANT+ Windows drivers is here: https://support.wahoofitness.com/hc/article_attachments/4408409938322/ant_usb2_drivers.zip Download and unzip it. open Windows “Device Manager” scroll down and find the USB ANT+ USB stick in the device list (it’ll likely be highlighted if it’s not working correctly) Right click the ANT+ USB stick, update driver, nigate to the spot you unzipped the driver and select itFun facts about ANT+: it’s older and has overlapping frequencies with things like microwe ovens so it’s prone to interference. However, it’s also fault-tolerant: unlike Bluetooth that requires “pairing”, ANT+ “transmits in the blind” - it simply spits out data for anything listening. Advantages are it can be received by multiple devices at once (example: HR can be sent by ANT+ to a bike computer, sport watch, and Zwift device on the same ANT+ channel) and it tends to reconnect after a disconnect. BLE, because of the “pairing” requirement, can only connect to a single device per channel and when a connection is dropped may stay dropped until manually re-connected. ANT+ has relatively long range and uses very little power, making it ideal for sensors using small coin cell batteries. ANT+ was created by a small Canadian company called Dynastream Innovations (hence the driver signature) which was bought by tech giant Garmin.
