Wake up from low-power mode with GPIOhttps://devzone.nordicsemi.com/f/nordic-q-a/80953/wake-up-from-low-power-mode-with-gpioWe want to use GPIO_12 as a wake up pin. (High -&gt; open uart, Low -&gt; close uart) Also, we have a timer and timeout set to 500ms. When we pull GPIO_12 to high, it seems not trigger an event to wakp up from idle_state_handle()/nrf_pwr_mgmt_run() immediatelyen-USTelligent Community 13Tue, 26 Oct 2021 04:56:29 GMTRE: Wake up from low-power mode with GPIOhttps://devzone.nordicsemi.com/thread/335842?ContentTypeID=1Tue, 26 Oct 2021 04:56:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a45fe360-76a9-4b7d-8bfc-8248052eca9cNorman Hsu<p>Hi <span>Vidar,</span></p> <p><span>After configuring the GPIOTE, the interrupt is work now.</span></p> <p><span>Thank you for guiding.</span></p><div style="clear:both;"></div>RE: Wake up from low-power mode with GPIOhttps://devzone.nordicsemi.com/thread/335485?ContentTypeID=1Fri, 22 Oct 2021 12:30:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea3e122d-6c6a-4634-9d4f-5a5af4158bf4Vidar Berg<p>Hello,</p> <p>The GPIO sense signal must be connected to the GPIO<strong>TE</strong> peripheral to generate an interrupt you can wake up on. I recommend you use the <span><a title="GPIOTE" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/hardware_driver_gpiote.html?cp=8_1_2_0_3">GPIOTE</a></span> driver to set this up.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
