Device does not come out of low power

[geert_venken]

We are using nRF52833 with Softdevice S113 for BLE.

in the OS_Idle function, nrf_pwr_mgmt_run is called.

But never comes out of sleep.

Is there a need to call nrf_drv_power_sleepevt_init?

Are examples available?

thanks

SD function?

Do you mean, if I replace WFE by WFI or visa versa in nrf_pwr_mgmt_run?

This does not make a difference, same behavior.

Sorry for the misunderstanding.

Now I got your point. In nrf_pwr_mgmt_run I removed all related to softdevice and always call __WFI.

No success.  Same behavior.

I also enabled PWR_MGMT_DEBUG_PIN_SET and routed this to a LED.  Goes on but never off.  

Watchdog resets the system.

It's my bad, I should have referenced the full function name without any abbreviation. Anyway, thanks for confirming that you see the same behavior with __WFI(). This suggests that the issue isn’t with the sleep function (__WFI() or nrf_pwr_mgmt_run()) but rather that the RTC isn’t triggering the wake-up interrupt as expected.
