The Softdevice will perform a scanning after the sd_ble_gap_connect() has been called regardless if the application has performed a scanning or not.&nbsp;The sequence chart for a connection establishment is shown <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s130.api.v2.0.1%2Fgroup___b_l_e___g_a_p___c_e_n_t_r_a_l___c_o_n_n___m_s_c.html">here</a>.&nbsp;</p> <p>Best regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
