https://devzone.nordicsemi.com/f/nordic-q-a/119230/bt-shell---board-resources-usedHello I started developing a BT shell based app on the nRf52840DK board and then moved to a custom board. In the overlay file, I&#39;ve deleted every nRf52840DK node I could think of (except of UART0) to prevent contention with the board&#39;s peripheralsen-USTelligent Community 13Mon, 24 Feb 2025 14:42:45 GMThttps://devzone.nordicsemi.com/thread/524387?ContentTypeID=1Mon, 24 Feb 2025 14:42:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c6ec35bd-ff1c-4810-8cd3-f1eb36e7b2b6Vidar Berg<p>Hello,</p> <p>This sample does not configure any GPIOs or peripherals that will toggle any output signa&nbsp;as far as I can tell(apart from the UART of course). You could check the generated zephyr.dts file for your application to confirm that the nodes are deleted, but I don&#39;t see any nodes that would have to be disabled or removed. Which GPIOS are you seeing this on? Did you check the signal wilth a scope or logic analyzer?</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
