Some of the time we need to keep another module on the board powered on when the nrf9160 isen-USTelligent Community 13Wed, 07 May 2025 09:26:28 GMTRE: GPIO levels behaving differently during reboot rather than sleep/wake on nRF9160https://devzone.nordicsemi.com/thread/534238?ContentTypeID=1Wed, 07 May 2025 09:26:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abb63ebf-38e4-4ee7-84ee-3bf190fabc53Jared<p>Hi,</p> <p>During a reset, the GPIO state is undefined.
