https://devzone.nordicsemi.com/f/nordic-q-a/13106/ble-softdevice-uart-not-possible-simultaneouslyI am trying to make a custom BLE service and be able to do debug it with UART at the same time. Just trying to print some UART messages at some points in the code. However, whenever I insert even on &#39;printf&#39; lines, the BLE fail to work.

Have you tried to test with \examples\ble_peripheral\ble_app_uart example ? In the example we use UART and BLE at the same time.</p><div style="clear:both;"></div>
