When I scan for Bluetooth on Android phones, Stop advertising

[HanKyul]

I use the Android 5.0.1 lollipop, SoftDevice S110 6.2.1 and SDK 5.2. When a Bluetooth scan performed on Android phones, 0x10 (Connect), the event occurs and after 0x12 (Conn Param Update), BEACON advertising will stop. In kitkat 0x10, 0x11 (Disconnect) has been carried out is still the Beacon advertising. Bluetooth scanning is conducted in a lollipop, Beacon want to allow advertising to be continued. The Bluetooth device search. BLE is not scanned. What should I do?

My conn_param_init are as follows:

connection_params_init.p_conn_params                  = NULL;
connection_params_init.first_conn_params_update_delay = APP_TIMER_TICKS(5000, APP_TIMER_PRESCALER);
connection_params_init.next_conn_params_update_delay  = APP_TIMER_TICKS(5000, APP_TIMER_PRESCALER) ;
connection_params_init.max_conn_params_update_count   = 3;
connection_params_init.start_on_notify_cccd_handle    = BLE_GATT_HANDLE_INVALID;
connection_params_init.disconnect_on_fail             = false;
connection_params_init.evt_handler                    = on_conn_params_evt;
connection_params_init.error_handler                  = conn_params_error_handler;

err_code = ble_conn_params_init(&connection_params_init);

@HanKyul: I'm not quite sure I understand you question.

Could you let me know why you allow connection with a beacon ? Note that when in connection the peripheral usually wouldn't be able to advertise.

You can try to capture a sniffer trace to understand what happens over the air.
