Watch dog + sd_power_system_off Is it possible?

[Mariko99]

Hello !

is possible turn off my system using sd_power_system_off  when the Watch dog is enabled?

After I called sd_power_system_off  my device is restarting and initialize everything again

details:

SDK13, nRF52

I was seeing this too:

• After calling sd_power_system_off(), the watchdog was restarting the system (shouldn't happen since all clocks should've been stopped).
• Using nrf_power_system_off() worked beautifully.

The issue was that I was calling __disable_irq() before entering my shutdown routine, and because the softdevice relies on interrupts, the call wasn't actually shutting down the system, which is why nrf_power_system_off() worked.
