Cyclemeter app paired with the Bluetooth but didn't register speed, it would just circle and say searching or would pop up and say N/A.
I use Cyclemeter on an iPhone with three Duotrap S-equipped bikes with no issues. When you spin up the bike prior to pairing, are you getting red and green lights on the sensor for the first ten revolutions of the crank and wheel? And are you pairing the sensor in the Cyclemeter app itself, or using the Bluetooth utility in the iPhone's settings? The pairing should be done entirely within the Cyclemeter app - you don't need the iPhone's settings utility for anything (other than making sure Bluetooth is on).
