Data not writing to file properly

[SaundersEngineering]

I've got an issue where the data isn't writing properly to the csv file or something. The x,y,z data does not change even a small amount, the entire column just stays the same even when the live data on the graph on the phone is clearly changing:

I have the same issue. Seems like app is writing data to the disk slower than it is receiving it

I have the same issue, data only seems to change about once every 3 seconds.

In addtion, t_Android is unusually large compare to y_unix

t_Android;t_unix;bpm;a
578933434000000;1737985622323;0.0;3

Are the 2 timestamp simply epoch_in_nano and epoch_in_milli?

1. these two timestamps are not changing much either.
2. Ocassionally a record in CSV will have missing value. Need to curate it
