Does the Power Profiler app have a pure coulomb counter mode?

[mcu8484]

I would like to use the Power Profiler app (with PPK II) as a pure coulomb counter for accurate long term (> many days) cumulative device energy consumption without saving individual data points.  So far, I can only see ways to disable live display of data points but not saving.  The problem is that I am running out of disk space even for temporary data storage due to the long run times.  It seems the app could just use collected data points for energy consumption updates then throw away the data without saving.  Any suggestion to accomplish the goal with the Power Profiler app would be appreciated.

Hello,

without saving individual data points.

No, I do not think we have a feature like that unfortunately.

What I guess you can do is to not sample that often, eg. just once per second, and then leave it going for multiple days. You can see in the file size estimation there that the resulting file won't be too large as long as you don't sample too often.

The problem is that I am running out of disk space even for temporary data storage due to the long run times. 

If the buffer or max disk size allowed by the app is the problem then I think you should be atleast be able to tweak the maximum buffer size using ctrl+alt+shift+A, though I am not seeing that working in v2.4.0 for some reason. My go-to resource for info on this app is unfortunately OOO at the moment, but this trick seems to work in v2 beta6 of the application, in case you want to give that a try, but it would of course be preferable not to downgrade.

Hello again,

I had a talk with one of the developers working on the app. In the newer versions of the app, no buffer is needed because we now no longer use the ram. For the same reason, you should now be able to record indefinitely, by changing the location of the tmp folder.

Though there is one caviat/issue: on Linux and macOS the connection seems to drop after some time, depending on the machine. Maybe this is what you are running into?

So for very long recordings we recommend using Windows.
