I just converted over from SDK8.0 to SDK8.1 to use the pwm library. After I was done, I figured out by searching on here that the GPIOTE is drawing ~1.1-1.2ma in sleep.
I assume this is from the change in the app_button library where it uses nrf_drv_gpiote vs app_gpiote?
The pwm library uses nrf_drv_gpiote too, but I don't care about extra current draw while pwm is active.
Do I need to port back and use the app_button library from sdk8.0?
