https://devzone.nordicsemi.com/f/nordic-q-a/88286/multiple-gpio-interrupts-from-system_soft_offI am developing a product that I have going into SYSTEM_SOFT_OFF to maximise battery life. I have a bunch of GPIOs (these are currently just buttons on the nRF52-DK) that I use to trigger the hardware out of this mode, and start up. I then check the registersen-USTelligent Community 13Wed, 25 May 2022 12:05:31 GMThttps://devzone.nordicsemi.com/thread/369515?ContentTypeID=1Wed, 25 May 2022 12:05:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5227eba9-5c74-471e-afbc-0f13391e31e9Simonr<p>Hi</p> <p>It sounds like you need a debounce on your wake up GPIO.&nbsp;This is implemented in the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_bsp.html">BSP </a>that is used in the SDK examples, but you can implement it yourself by combining the<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_button.html"> button handling library </a>to do debouncing and the app_timer to measure duration of the button press. Note that I assume you&#39;re using the nRF5 SDK here. Let me know if that&#39;s not the case, but the functions you refer to looks like that.</p> <p>You can check out<a href="https://devzone.nordicsemi.com/f/nordic-q-a/51942/gpio-interrupt-after-wake-up/208846#208846"> this case</a> where my colleague Håkon explains and discusses a similar issue as well.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
