*This is a fork of the CSCSensor app using the layout library and separate module for CSC functionality. It also drops persistence of total distance on the Bangle, as this information is also persisted on the sensor itself. Further, it allows configuration of display units (metric/imperial) independent of chosen locale. Finally, multiple sensors can be used and wheel circumference can be configured for each sensor individually.*
Other than in the original version of the app, total distance is not stored on the Bangle, but instead is calculated from the CWR (cumulative wheel revolutions) reported by the sensor. This metric is, according to the BLE spec, an absolute value that persists throughout the lifetime of the sensor and never rolls over.
Upon first connection, close the app afain and enter the settings app to configure the wheel circumference. The total circumference is (cm + mm) - it is split up into two values for ease of configuration. Check the status screen inside the Cycling app while connected to see the address of the currently connected sensor (if you need to differentiate between multiple sensors).
