Looking through the documentation and examples for the nRF9160, they all seem to be based on the Zephyr RTOS. I have 2 questions: Is there any benefit (mainly from a power savings standpoint), to program the nRF9160 as baremetal? Our application is simple - we don't have timing constraints and can use an event driven system if it can save power. Memory isn't a concern and the M33 should be sufficient for either OS type (Zephyr or baremetal). Can baremetal (non-Zephyr) programming support the cellular and other Nordic specific peripherals (outside of the M33 spec)? Are there examples for these types of projects? Thanks
