Assuming I&#39;m not using RTS/CTS as I have disabled flow control, can I define RX_PIN_NUMBER and TX_PIN_NUMBER as GPIO pins that are left open/noten-USTelligent Community 13Sat, 05 Mar 2016 14:26:20 GMThttps://devzone.nordicsemi.com/thread/46718?ContentTypeID=1Sat, 05 Mar 2016 14:26:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:349d0fc9-50ca-4f9c-8a78-8edcea4ab0aaawneil<p>As you say, UART-BLE is purely an <strong><em>emulation</em></strong> - so physical connections/wiring are entirely irrelevant to that.</p><div style="clear:both;"></div>
