https://devzone.nordicsemi.com/f/nordic-q-a/2493/sleep-example-nrf51422-ant-s210Hey All, I am working on a board that is based on the nrf51422. The system goes to sleep and gets woken by an interrupt. One of the programmers claims to have managed sleep current in the tens of uA.

Do you disconnect or set the GPIOs on the chip to a known level before going to sleep? Do you have some sensors that a connected to the nRF51422 that could be still powered up through the GPIO?</p><div style="clear:both;"></div>
