https://devzone.nordicsemi.com/f/nordic-q-a/15390/advertising-during-connection-nrf5-sdk-11-s132Hello, my application has to emit measurements in the manufacturer specific data structure continuously and has to accept a connection, for example for ANCS. Therefore I extended the BLE_GAP_EVT_CONNECTED case of the ble_app_ancs_c example like thisen-USTelligent Community 13Fri, 29 Jul 2016 08:57:18 GMThttps://devzone.nordicsemi.com/thread/58765?ContentTypeID=1Fri, 29 Jul 2016 08:57:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a525d696-9171-4948-9072-78f6539b0c05Ole Bauck<p>When advertising while being in a connection the advertising type cannot be connectable. As said in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.api.v1.0.0/group___b_l_e___g_a_p___f_u_n_c_t_i_o_n_s.html#gab82c978db30188c7f4fbf2dac1d97720">sd_ble_gap_adv_start</a> documentation:</p> <blockquote> <p>An application can start an advertising procedure for broadcasting purposes while a connection is active. After a BLE_GAP_EVT_CONNECTED event is received, this function may therefore be called to start a broadcast advertising procedure. The advertising procedure cannot however be connectable (it must be of type BLE_GAP_ADV_TYPE_ADV_SCAN_IND or BLE_GAP_ADV_TYPE_ADV_NONCONN_IND).</p> </blockquote><div style="clear:both;"></div>
