I’m getting back onto the trainer after a few years. I previously used a USB Ant+ dongle on my laptop to receive data from my Garmin Speed/Cadence Sensor. I would like to use an IOS device going forward. Would a Garmin Speed Sensor 2 work to send to my IOS device over bluetooth, or would I be better off replacing my old Garmin 500 head unit?
If you planning to run the TR app on the iOS device, the BLE transmission from the Garmin sensor will be fine for use with VirtualPower.
