cptel Is there a way to know if the nRF9151 powered-up because of Hibernate timeout, EN line pull down or internal reset?
jaredwolff There’s a reset cause: https://docs.nordicsemi.com/bundle/ps_npm1300/page/chapters/core_components/ctrl_reg/doc/error_log.html#register.RSTCAUSE There’s also a register to read the current status of the ship hold input. You could also read the status of USB to see if it’s active. Hope that helps!
