Sorry, I thought I was clear. Perhaps it is the nomenclature.

I am trying to set the logging interval. I go to the upper right of the main screen to select preferences. I come to the screen that allows you to set logging interval: max, 1 sec, 10 seconds, 1 minute.

I select (for example) 1 minute. The 1 minute button turns gree. I return to the main screen. It says “applying preferences”. I press “logging on”. the button turns green.

When I read the data from the SD card, I get a data point every 0.301 seconds, so the logging rate is about 3 samples/second. It does not matter if I select 1 sec, 10 sec or 1 minute, the logging rate does not change. It is always approx. 3 samples/second.

I have rebooted phone and Mooshimeter many times, tried various order of sequences. I have upgraded firmware, reinstalled the app. The set logging rate does not work at all.

I have tried 5 different devices, different phones, different Android versions (v 6, V5) as well as IOS. The behavior is the same. There is no way to change the logging rate with any device.

I really like the Moshimeter idea, but this unit is not performing properly.

If no one can assist in troubleshooting, I will have to return it.
