how to put nRF52 in "System Off" mode?

The deepest power saving mode of the nRF52 is "System Off". Is there a way
to do this in mynewt?

Thanks,

Carl

Ok, I see the hal_bsp_power_state(int state) hook.

For now I can just do:

NRF_POWER->SYSTEMOFF = 1

Thanks,

Carl

Mynewt does not provide a way to do this currently. There are hooks in the bsp code for power modes and you could add that code to the deepest power savings mode if you like (user-defined what happens on various power states).
