I just tried the new Windows XeThru Explorer 2.5.2 with the X4M200 1.3.1 firmware update to get the breathing pattern. All works great so far. In my early tests this new value seems to start/end when the RPM value starts/ends and AFAIK that is as designed only happening when the movement is 'slow' enough. Not sure the details. Is there any way to ask for immediate breathing pattern values via an API?
