Developer feature debug warning: The debug warnings are only available to developers who activate the feature via compile switch. After that it is possible to define a condition and a content of a warning which will be shown if a special situation occure (visualized in the main view as already done for other warnings like ppo2). In the first implementation details regarding the error state of the DiveO2 will be shown in case the sensor reports a problem. Feel free to change the implementation in case you want to observe another behavior.
