&lt;p&gt;We do not have any official examples, but you can find posts on DevZone with code, for instance in &lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/50297/creating-whitelist-with-pm-on-manually-added-peer-error-0x12802-ble_error_gap_invalid_ble_addr/204077#204077"&gt;this post&lt;/a&gt;. We do not have any examples of this for Mobile devices, but there is some information out there, as this requires the same BLE API as other forms of out of band pairing (typically NFC). See for instance &lt;a href="https://stackoverflow.com/questions/57989084/nfc-bluetooth-le-oob-pairing-android-application-launch"&gt;this thread&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Secure BLE with preinstalled Keys</title><link>https://devzone.nordicsemi.com/thread/267272?ContentTypeID=1</link><pubDate>Mon, 31 Aug 2020 13:48:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a2add2d5-19b0-4427-bb16-40798ce684d1</guid><dc:creator>TRIXO</dc:creator><description>&lt;p&gt;Hi Einar,&lt;br /&gt;&lt;br /&gt;I have read through your post. Do You guys have any example code? Either for Java or Device part.&lt;br /&gt;Is it possible to insert the key somehow using your android BLE lib ?&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Thanks for your quick reply.&lt;br /&gt;&lt;br /&gt;Best,&lt;br /&gt;T&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Secure BLE with preinstalled Keys</title><link>https://devzone.nordicsemi.com/thread/267264?ContentTypeID=1</link><pubDate>Mon, 31 Aug 2020 13:25:33 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:e9fb1312-2c99-4735-a593-e8308d33bfd9</guid><dc:creator>Einar Thorsrud</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;There are a few ways to do this (and a few reasons why you may want to avoid it). Please see &lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/47110/proof-of-concept-with-pre-bonded-ltk/186158#186158"&gt;this post&lt;/a&gt; and the posts it refers to.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
