nrf_pwr_mgmt_run() vs sd_app_evt_wait()

[adamsperry]

I'm struggling to understand the difference between nrf_pwr_mgmt_run() and sd_app_evt_wait(). When should I use each one? It looks like nrf_pwr_mgmt_run() calls sd_app_evt_wait() so is it safe to just always use nrf_pwr_mgmt_run()? Is there a reason I would want to bypass nrf_pwr_mgmt_run() and call sd_app_evt_wait() directly?

Hi, 

It depends on you would like to use the power management feature or not. You could use nrf_pwr_mgmt_run() as our most of the example. If you want to use sd_app_evt_wait(), please be aware of the function note.

What "function note" are you referring to if I want to use sd_app_evt_wait()?

See sd_app_evt_wait:

Note.

The application must ensure that the pended flag is cleared using sd_nvic_ClearPendingIRQ in order to sleep using this function. This is only necessary for disabled interrupts, as the interrupt handler will clear the pending flag automatically for enabled interrupts.If an application interrupt has happened since the last time sd_app_evt_wait was called this function will return immediately and not go to sleep. This is to avoid race conditions that can occur when a flag is updated in the interrupt handler and processed in the main loop.
