I’ve got the FNB38 and it’s pretty nice. Despite having a “logging” function, I can’t find any way to export data off the darn thing. So I’m curious how the bluetooth functionality works on this one. Particularly if you’re able to get data or a graph for the entire charge cycle. I use mine for checking the built-in charge function of flashlights for reviews and I find myself wanting more than the basic summary info that the FNB38 provides.
