If the BLE example include the Peer Manager library, then the example support bonding, ref documentation:&nbsp;<br /><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_peer_manager.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_peer_manager.html</a>&nbsp;and&nbsp;<br /><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_pm_usage.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_pm_usage.html</a>&nbsp;</p> <p>If you want to understand more about the BLE events and softdevice api the Peer Manager is calling you can find BLE message sequence charts useful:<br /><a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s140.api.v7.3.0/group___b_l_e___g_a_p___p_e_r_i_p_h___s_e_c___m_s_c.html">https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s140.api.v7.3.0/group___b_l_e___g_a_p___p_e_r_i_p_h___s_e_c___m_s_c.html</a>&nbsp;and<br /><a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s140.api.v7.3.0/group___b_l_e___g_a_p___p_e_r_i_p_h___l_e_g_a_c_y___m_s_c.html">https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s140.api.v7.3.0/group___b_l_e___g_a_p___p_e_r_i_p_h___l_e_g_a_c_y___m_s_c.html</a>&nbsp;&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
