There is no support for configuring the UART in any way using the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/lib_nrf_log.html">logging library</a>. The library is experimental in it&#39;s current state, so this may change in the future. For now you have to modify the implementation in nrf_log.c, though I agree that this is not elegant. I have suggested internally that this should be improved.</p><div style="clear:both;"></div>
