But what did you mean by unwanted behaviour. Will the Gpio stop working or will it only be a Gpio state reading issue?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/511597?ContentTypeID=1Fri, 22 Nov 2024 06:38:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd140476-b872-4da3-a09e-b4660968ccf9Priyanka<p>Hi Nishith,</p> <p>It is generally not recommended to set a single pin as both output and input as it can cause unwanted confusion and also maybe unwanted behaviour later on.</p> <p>You could maybe try to read the state of LED1 into a variable and then use this to control the LED2 state.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
