What is the CABLE Util app used for?

The CABLE Util app is essential to setting up your ANT+ sensors to Bluetooth. It is used for pairing sensor sets to CABLE.  

 You do not need to use CABLE Util anymore thereafter, unless you want to change or add sensors, update CABLE firmware, or test out your sensors.

Leaving CABLE Util running in the background can cause connectivity issues. It is not needed to provide any bridging connection to your fitness application. All the data sent from CABLE to your app comes through the Bluetooth services generated by the CABLE device. 

NOTE: CABLE Util is currently only available for iOS devices.
