Hi,

this is intended to inform the fuel gauge when the PMIC has VBUS connected. The reason is that when VBUS is connected, power is typically drawn from VBUS instead of the battery.

So, this should be set to True if there is a VBUS powering the system instead of the battery.

In the most recent fuel gauge version (v.1.0.0 in sdk-nrfxlib main), we have changed this API to a more generic way of conveying relevant external factors to the library.

I dont know why you get a secure fault though. What is the stack size of the thread running `nrf_fuel_gauge_process`?

We have an interrupt set up for the pmic to notify the nrf9160 when it is being charged, so we were setting the vbus present based on that

Hello, where did you get the vbus present from?

In the nrf_fuel_gauge_process documentation for NCD 2.7.0 I don't see anything like that.

Best regards,

Michal
