Hello, has been a while since the last response. Hoping to get answers to the questions below.    ... View more

Thanks, this poses a number of questions for me.  1) In the VirtualTapActivity virtual sensor do I have two triggerSource clauses or indicate multiple virtual sensors within the same clause?  2) Do I need to specify both physicalSensors as well in the descriptor? 3) In order to determine which sensor's data I am dealing with at the time of trigger, I assume I am looking at VirtualSensorDescriptor.triggerSource?  4) If I understand correctly, I need to use the timestamp from the two trigger sources in order to record and compose the data when there has been an event from both sensors in the same meaningful time window?  Thank you.  ...

Thank you, this is helpful. I have a tangible use case where I would like to use the combined data from the accelerometer with readings from an ambient light sensor in order to have a virtual sensor provide a derived data stream.  I would like to have the samples from both physical sensor available to the virtual sensor in order to derive a new outcome and report it to the end user. Without sharing variables between the drivers, is it possible to accomplish this?  From a triggering perspective, my preference would be to trigger this on the accelerometer (recognizing a tap activity) and allow the virtual sensor to combine this with data from the ambient light sensor.  Trying to better understand how to accomplish this within the architecture of the BHI260.    ...
