How to get raw data

Post by hiroko »

I got the raw data as a csv file using an iOS tablet. "R Recording Interval" was set to "constant".

I want to acquire data at regular intervals, but the data acquisition intervals are not constant.
-There is the same millisecond data.
・ There is a gap.

Please tell me the reason and how to set it.

To see the timestamp correctly in Excel, set the format to this:

yyyy-mm-dd hh:mm:ss.000

This will show you the full timestamp as Year-Month-Day Hour:Minute:Second.Microsecond

This is unfortunatley normal. Bluetooth buffering means the packets are not consistently spaced.
