Also, you have to make sure to reply to the event asking for a passkey, as shown <a href="http://devzone.nordicsemi.com/documentation/nrf51/4.4.0/html/group___b_l_e___g_a_p___b_o_n_d_i_n_g___p_k___p_e_r_i_p_h___m_s_c.html">here</a>.</p> <p>I&#39;d also recommend you to take a look at the ble_app_gls application in the SDK, which implements this, and other questions here on Developer Zone, for example <a href="http://devzone.nordicsemi.com/index.php/pincode">this</a>.</p><div style="clear:both;"></div>
