https://devzone.nordicsemi.com/f/nordic-q-a/2747/ble-pairingHello Gentlemen, I&#39;m looking for sample code that shows how to enable security which prompts for a PIN number on the Android device when I want to connect to the nRF. Once this works I also would like to see some source showing how to set a newen-USTelligent Community 13Fri, 13 Jun 2014 09:15:30 GMThttps://devzone.nordicsemi.com/thread/10646?ContentTypeID=1Fri, 13 Jun 2014 09:15:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29dc0376-b67f-4e67-9183-40318402fe41&#216;yvind<p>Hi,</p> <blockquote> <p>Once this works I also would like to see some source showing how to set a new pin number each time.</p> </blockquote> <p>The PIN is randomly generated by one of the devices (which one depends on their I/O capabilities) every time pairing is done. On other words, no action needs to be taken to get a new PIN number.</p> <p>Best regards,</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10645?ContentTypeID=1Fri, 13 Jun 2014 08:15:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e677e5a0-a50e-4d0f-80a6-ad29960b1b10FormerMember<p>The implementation should follow the message sequence chart for <a href="https://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/a00898.html">GAP Peripheral Bonding: Passkey Entry (Central display) or OOB MSC</a>. Unfortunately I don&#39;t think there are any examples for this in the SDK</p> <p>The opposite of what you want is implemented in ble_app_gls example in the SDK, it implements pairing where the nRF51822/peripheral has a display and shows the pin on a screen. And then, the master/central should type the passkey showed on the peripheral&#39;s display. It is implemented according to <a href="https://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/a00897.html">GAP Peripheral Bonding: Passkey Entry, Peripheral displays</a> message seqence chart.</p><div style="clear:both;"></div>
