There is such a programmer on-board on our DKs, which you can use from their &quot;Debug out&quot; port. For modules there are usually some programmer pins or pads that you can connect to.</p> <p>It is hard to tell where the error might be. What is your setup, what is connected to what? Can you share an image of your setup?</p> <p>Have you tried using nrfjprog?</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
