I have decided that a refurbished 6th gen 2018 I pad is the most reasonable device for using my wife’s Kickr Snap. Since the Snap does not do cadence I will get her a cadence sensor, as well as a HR strap. On my laptop setup these devices need a receiver dongle in a USB port. Being new to I Pads what is the setup with them and sensors? I assume internal Bluetooth but want to make sure.
