The reason is that the Segger chip requires the use of flow control for the UART to function correctly, and this is not part of the DTM specification, and hence not supported by nRFgo Studio&#39;s DTM application.</p> <p>If however you hook up another serial port to the correct pins on the Evaluation Kit in some way (better not use the one that is connected to the Segger chip), this should be doable. I just tested this using the RS232 level converter on the motherboard with pins 1 and 3, and that works nicely.</p><div style="clear:both;"></div>
