https://devzone.nordicsemi.com/f/nordic-q-a/32856/re-init-after-uninit-re-enable-after-disable-doesn-t-work-using-gpioteHi Nordic, I find somethig wrong while using GPIOTE. I. First I call nrf_drv_gpiote_out_init(MY_PIN, &amp;my_config), it works fine. However, I call nrf_drv_gpiote_out_uninit(MY_PIN) , and call nrf_drv_gpiote_out_init(MY_PIN, &amp;my_config) later, MY_PINen-USTelligent Community 13Wed, 04 Apr 2018 12:54:04 GMThttps://devzone.nordicsemi.com/thread/126852?ContentTypeID=1Wed, 04 Apr 2018 12:54:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0d62ec1e-730b-4673-a463-cc56dfceeb14FormerMember<p>The easiest way to debug this problem is to run the chip in debug mode, step through the code and watch the GPIOTE and GPIO registers &quot;on-the-fly&quot;. When doing so, you can check which settings that are changed when disabling and enabling the GPIOTE task.</p><div style="clear:both;"></div>
