Please answer my question. 
 I repeated the Bluetooth pairing ON → OFF of my smartphone and DK 52
(PCA 10040 + HRM) and checked the connection, I encountered a mysterious phenomenon.
HRM : heart_rate_demo.hex 
 
 
 It is a phenomenon</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 23 Oct 2017 08:49:39 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/26092/mystery-that-makes-pairing-impossible-using-dk-52-10040" /><item><title>RE: Mystery that makes pairing impossible using DK 52(10040)</title><link>https://devzone.nordicsemi.com/thread/102831?ContentTypeID=1</link><pubDate>Mon, 23 Oct 2017 08:49:39 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:cb378863-3163-4635-a036-9396659afefe</guid><dc:creator>Bj&amp;#248;rn Kvaale</dc:creator><description>&lt;p&gt;Could you first download the SDK 14.1.0 &lt;a href="https://www.nordicsemi.com/eng/nordic/Products/nRF5-SDK/nRF5-SDK-zip/59011"&gt;from this location&lt;/a&gt;? Then, could you please download nrf go studio (either &lt;a href="https://www.nordicsemi.com/chi/nordic/Products/nRFgo-Studio/nRFgo-Studio-Win32/22286"&gt;32-bit&lt;/a&gt; or &lt;a href="https://www.nordicsemi.com/chi/nordic/Products/nRFgo-Studio/nRFgo-Studio-Win64/14964"&gt;64-bit&lt;/a&gt;). Lastly, could you unzip the sdk 14.1.0, open nrf go studio, attach your dk to the pc via usb, find the dk under Device Managers (should be called Segger and then a number), press the erase all button &amp;amp; finally press on the Program Application tab. There, you can browse for a hex file. I want you to find the hex file under examples/ble_peripheral/ble_app_hrs/hex/ble_app_hrs_pca10040_s132.hex &amp;amp; flash this hex file to your dk. Lastly, download the nrf toolbox app from iOS or Android, open the HRM example &amp;amp; try to connect to your dk.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Mystery that makes pairing impossible using DK 52(10040)</title><link>https://devzone.nordicsemi.com/thread/102832?ContentTypeID=1</link><pubDate>Fri, 20 Oct 2017 11:30:46 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:98377fba-d2d3-4aac-86ef-8f971c8f9996</guid><dc:creator>Hiro</dc:creator><description>&lt;p&gt;To the DK board just purchased (PCA 10040 V 1.2.1 / 2017.22)
I use Sample Code on WEB.
It is only possible to examine it on the WEB to see which SDK was coded.

&lt;p&gt;I have not compiled on SDK yet.
Can you get any information?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Mystery that makes pairing impossible using DK 52(10040)</title><link>https://devzone.nordicsemi.com/thread/102833?ContentTypeID=1</link><pubDate>Fri, 20 Oct 2017 09:18:13 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:bf65a251-6c41-480d-8376-4f77c252c436</guid><dc:creator>Bj&amp;#248;rn Kvaale</dc:creator><description>&lt;p&gt;Which SDK are you currently using?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
