Just getting started and trying to pair the iPhone via Bluetooth is a dead end. I’ll subscribe when you get the IOS app working since I don’t care to spring for the Ant+ Dongle. TrainerRoad until then.
Try cranking the pedals when you are in the pairing menu. My bluetooth power and cadence sensors don’t appear until I move the pedals, but once I do they show up every single time. It seems some bluetooth sensors sleep until there is movement.
