Then you follow this sequence chart: <a href="http://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v8.x.x/doc/8.0.0/s120/html/a00581.html">developer.nordicsemi.com/.../a00581.html</a> To display the passkey and then the end user on the peer device can enter the passkey that you display.</p> <p>I don&#39;t see any issue with the timing here.</p><div style="clear:both;"></div>
