It&#39;s not Nordic&#39;s development kit. There is no programmer on it. You need an external programmer (or a Nordic&#39;s DK) to program the chip.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73043?ContentTypeID=1Tue, 10 Jan 2017 23:29:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b31dffe7-e70b-40ea-b60e-91d9bed2a0d5kalreg<p>I did - no results. Tried on windows 7 and 8. I use WaveShare NRF51 DK. It lights up the SPD led after connecting for 10 secs, and then led turns off. Is it normal behaviour? I am not sure if board is damaged or maybe a wire, but dont have another to check it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73042?ContentTypeID=1Tue, 10 Jan 2017 21:12:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc931fa4-a1db-4a8e-b542-ee76121b638bDaniel Wang<p>Try to install the jlink drivers: <a href="https://www.segger.com/downloads/jlink">www.segger.com/.../jlink</a> &quot;J-Link Software and Documentation Pack&quot;</p><div style="clear:both;"></div>
