https://devzone.nordicsemi.com/f/nordic-q-a/15772/wake-up-from-system-off-using-gpioHi, i am trying to wake up the nrf52832 from system off with a gpio interrupt. When the signal on my gpio pin 28 goes from Hi to Lo, i trigger a callback function in which i set the nrf52832 to system off. When the signal on the pin goes from Loen-USTelligent Community 13Thu, 18 Aug 2016 23:24:41 GMThttps://devzone.nordicsemi.com/thread/60183?ContentTypeID=1Thu, 18 Aug 2016 23:24:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a3e8be4d-c8ac-4500-9964-9dd1e9a0b7e4Tizana<p>i have the same problem and unfortunately we didn&#39;t have any answer.</p> <p>but i did some try and i notice that when i add this code line the input PIN 28 will woke up the nrf.</p> <pre><code>nrf_gpio_cfg_sense_input(28, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_SENSE_HIGH); </code></pre> <p>the problem is when you are in system off and the pin 28 goes from Lo to Hi the nrf won&#39;t execute the callback function which you called on_power_low() but the system will reset and start executing from the beginning of the main file.</p> <p>unfortunately i didn&#39;t found any information about how to wake up the nrf, i had to struggle and looking for many example to find out this line to add in order to wake up the nrf</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/60182?ContentTypeID=1Wed, 17 Aug 2016 23:44:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c530234-5342-41cb-aa6e-f923c33d70b4Tizana<p>have the same problems, hope getting answere</p><div style="clear:both;"></div>
