Debug in (3) is when you wanted to use the NRF chip on the DK with an external Debugger.</p> <p>Also remember the procedure to put the interface firmware binary back on, its easy to trigger the Debugger bootloader by accident and it won&#39;t clean up after itself with a power cycle. See manual for details.</p><div style="clear:both;"></div>
