Hi,

Thanks Jared.

For the Uart, I ended up with calls to pm_device_action_run() with actions PM_DEVICE_ACTION_SUSPEND and PM_DEVICE_ACTION_RESUME. Actions PM_DEVICE_ACTION_TURN_OFF/ON are not implemented for the Uart.

I bookmarked the example from your answer for just in case I needed in the future.

Hi,

In some cases the device power management module will call nrfx uninit function of the device peripheral when you run pw_device_action_run() with SUSPEND.

In some cases there is no implementation of the SUSPEND task for the peripheral which means that it will have no effect for that device. Therefore, I suggest using nrfx directly and call the uninit function of each peripheral when you're done using them. Same goes for init.

See this sample,
