datalogger bandwidth issues - https://www.sparkfun.com/products/20594

i have been attempting to configure the IoT - 9dof to store data at various rate(s) and so far, things appear to be mostly working, but only for limited file size and/or entries into the file itself.

my goal is to log data at 100hz for all sensors native to the 9dof unit itself and the temperature as well.

also, FWIW, i am using the milliseconds since startup as a timestamp and so far, it has little to no correlation with the logging rate specified even when the rate is downsampled to ~5-10hz (compared to 100hz which is my goal).

if the user community had access to an arduino sketch that implements the .bin image, my guess is we could have something working relatively quickly...

The latest firmware (in preview right now) includes:

• Performance enhancements for faster logging rates
• Rate metrics - that capture the actual logging time values and can output the log rates. Helpful in determining log rate

This firmware is available here: https://github.com/sparkfun/SparkFun_DataLogger/releases/tag/v01.01.99
