https://devzone.nordicsemi.com/f/nordic-q-a/82907/pin-on-tracedata-not-aviable-if-bluetooth-is-enabledHello,
 I have a problem when I enable Bluetooth on my application. If I enable Bluetooth, I can&#39;t control gpio pin on Trace DATA. If I disable Bluetooth, I can.
 It&#39;s a hardware issue or I need to add some define on my proj conf to allow this ? en-USTelligent Community 13Mon, 20 Dec 2021 11:03:54 GMThttps://devzone.nordicsemi.com/thread/344319?ContentTypeID=1Mon, 20 Dec 2021 11:03:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:01d0c165-4d2a-49da-9250-0c63d76d3739Kenneth<p>Hi,</p> <p>I guess you can check the&nbsp;\zephyr\samples\bluetooth\hci_rpmsg for the debug_overlay and prj.conf if you by accident have enabled TRACE. But I think your problem may be instead that pin8 is used by a different pripheral, P0.08-9 are by default used as buttons:</p> <p><a href="https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L55">https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L55</a></p> <p>For test you can try to comment out those lines, if that make the pin work as expected, then you can make an .overlay in your project where you use the&nbsp;<span>/delete-property/ pin_name or change the pin used by buttons.</span></p> <p><span>Kenneth</span></p><div style="clear:both;"></div>
