https://devzone.nordicsemi.com/f/nordic-q-a/85827/oob-via-uartI am planning on pairing two parts of my system using OOB pairing via a UART connection. I couldn&#39;t find many examples of pairing using a physical connection as oppose to NFC and just wanted to check if there are any security issues that could arise fromen-USTelligent Community 13Tue, 15 Mar 2022 17:08:31 GMThttps://devzone.nordicsemi.com/thread/358288?ContentTypeID=1Tue, 15 Mar 2022 17:08:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6799f52f-57b9-422e-ae11-20bfe60de7e7GabiW<p>Great, thank you!&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/358189?ContentTypeID=1Tue, 15 Mar 2022 12:05:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8cc3e3fd-9915-4d7b-aeae-5029fa62a54eHung Bui<p>Hi Gabi,&nbsp;</p> <p>I don&#39;t see any problem doing OOB pairing via UART as long as it&#39;s a different mean of communication other than BLE. From my point of view it&#39;s even more secure than NFC.</p> <p>I guess it&#39;s just not common to use a wired connection to pair for a wireless connection. That could be the reason most of the OOB examples you find were using NFC.&nbsp;</p><div style="clear:both;"></div>
