https://devzone.nordicsemi.com/f/nordic-q-a/73448/using-the-buttons-handler-module-in-the-usbd-ble-uart-exampleIn the usbd_ble_uart example (SDK 17.0.2), I&#39;d like to use the buttons handler module (the same one from the BLE Blinky example), instead of the BSP BLE button events. In SDK config, I&#39;ve disabled BSP_BTN_BLE_ENABLED and enabled BUTTON_ENABLED .

In the meantime, the issue has become irrelevant on my side (ended up not needing buttons). Thanks a lot for your support anyways!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/302768?ContentTypeID=1Wed, 31 Mar 2021 13:37:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd9c02fa-85f4-45bd-a82c-3eb2f1df5dacEdvin<p>Hello,</p> <p>Does the project compile? I have seen that Keil from time to time underlines variables like this, saying it is not defined, but yet it compiles just fine either way, without any mention of those variables.</p> <p></p> <p>If it doesn&#39;t compile, can you please zip the project and upload it here so that I can try to reproduce it?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
