Hello,

Could you export the .gg file from the gauge so we can take a look at your settings?

If you could run a small test as well, start the logging function in bqStudio then apply a current above the sleep current, then log for a couple minutes to see if the gauge switches to sleep mode. When you log the data we can also see the other registers and debug your problem faster.

Sincerely,

Wyatt Keller
