    I am new to the Xethru product; I have a X4M200 and I am taking some data. When reviewing my log files, I keep seeing that any sort of data relating to the heart (via the Vital Signs .csv file created) shows up as a NaN. I was wondering why that is? Can I do anything for it to show up as a number which I can use? I have attached a spreadsheet from my testing as an example.

    X4M200 is only respiration sensor, it does not support heart rate output, so the vital-signs message will report NaN for invalid info.
