An nRF51822 example that used OOB authenticationhttps://devzone.nordicsemi.com/f/nordic-q-a/11108/an-nrf51822-example-that-used-oob-authenticationIs there any nRF51 SDK example that used OOB authentication? I&#39;ll not have any I/0 or display on peripheral side, and my central will be a mobile app, with connection to internet.en-USTelligent Community 13Mon, 04 Jan 2016 10:34:48 GMTRE: An nRF51822 example that used OOB authenticationhttps://devzone.nordicsemi.com/thread/41592?ContentTypeID=1Mon, 04 Jan 2016 10:34:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56cf3fc9-f48f-4995-b44e-2797db70327e&#216;yvind Karlsen<p>Hi,</p> <p>We do not have any examples that show how to do out of band authentication for the nRF51 series. What you would need to do is transfer the authentication codes to both central and peripheral units via some physical communication protocol, for example UART.</p> <p>For the nRF52 series however we have examples for out of band pairing using NFC, have a look at this example from SDK 11 where <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/ble_sdk_app_hrs_pairing_nfc.html?resultof=%22%70%61%69%72%69%6e%67%22%20%22%70%61%69%72%22%20%22%6f%76%65%72%22%20%22%6e%66%63%22%20">heart rate with pairing over NFC is demonstrated</a>.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
