We don&#39;t have any example on OOB with the library.&nbsp;<br />I did a quick search and it seems that you need to prepare the temporary key (OOB key) in the BLE pre-pairing data. It&#39;s described <a href="https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/bluetooth-prepairing">here.</a></p> <p>I would suggest you to seek help on this topic from Microsoft support channel.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/301348?ContentTypeID=1Tue, 23 Mar 2021 09:13:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8aabb4aa-3c1a-4d66-a732-5ae46b0ae4ebarikramon<p>With just connect every thing is working OK.</p> <p>The problem is on the windows side: which dot net library to use, which supports OOB connection</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/300910?ContentTypeID=1Fri, 19 Mar 2021 11:57:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4642d76b-8e23-4dd4-8025-2132006aabeeHung Bui<p>Hi Arik,&nbsp;<br />Could you describe what exactly occurred when you tested?&nbsp;</p> <p>Do you have NFC reader on your PC ?&nbsp;</p> <p>Did you managed to get it work with passkey/numeric comparison ?&nbsp;</p><div style="clear:both;"></div>
