You have to enable the directed advertisement and set the interval and timeout for directed slow advertisement. Add this to advertising_init():

options.ble_adv_directed_enabled = BLE_ADV_DIRECTED_ENABLED;

options.ble_adv_directed_slow_enabled = BLE_ADV_DIRECTED_SLOW_ENABLED;
options.ble_adv_directed_slow_interval = APP_ADV_DIRECTED_INTERVAL;
options.ble_adv_directed_slow_timeout = APP_ADV_DIRECTED_TIMEOUT_IN_SECONDS;

See this message sequence chart.

When you start directed advertisement you will get a BLE_ADV_EVT_PEER_ADDR_REQUEST event. There you will have to call ble_advertising_peer_addr_reply(ble_gap_addr_t * p_peer_addr) with the peer address.
