https://devzone.nordicsemi.com/f/nordic-q-a/66023/nrf9160-clock-timingDear Sir. Attached a code . It takes about 20 seconds from power on until the Blue Led is On. The timing of the Blue Led is about 2 sec , as in the code. Commenting all lines beside the io_init(); , a delay of 20 seconds is still on.

Also setting it on before a lot of the calls can help you see where the time is lost in startup, by then turning it off where you now turn it on</p><div style="clear:both;"></div>
