How can I short the time after I power on my BLE device with ble_app_hids_mouse?

It takes about 30s after I power my nrf51822 DK with ble_app_hids_mouse demo, how can I short it less than 10s ?

In the code there is a line "#define NEXT_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(30000, APP_TIMER_PRESCALER) /**< Time between each call to sd_ble_gap_conn_param_update after the first (30 seconds). */ "

I try to change 30000 to 10000 ,but it seems not work .

And I see the comment like this :

typedef struct
{
    ble_gap_conn_params_t *       p_conn_params;                    /**< Pointer to the connection parameters desired by the application. When calling ble_conn_params_init, if this parameter is set to NULL, the connection parameters will be fetched from host. */
    uint32_t                      first_conn_params_update_delay;   /**< Time from initiating event (connect or start of notification) to first time sd_ble_gap_conn_param_update is called (in number of timer ticks). */
    uint32_t                      next_conn_params_update_delay;    /**< Time between each call to sd_ble_gap_conn_param_update after the first (in number of timer ticks). Recommended value 30 seconds as per BLUETOOTH SPECIFICATION Version 4.0. */
    uint8_t                       max_conn_params_update_count;     /**< Number of attempts before giving up the negotiation. */
    uint16_t                      start_on_notify_cccd_handle;      /**< If procedure is to be started when notification is started, set this to the handle of the corresponding CCCD. Set to BLE_GATT_HANDLE_INVALID if procedure is to be started on connect event. */
    bool                          disconnect_on_fail;               /**< Set to TRUE if a failed connection parameters update shall cause an automatic disconnection, set to FALSE otherwise. */
    ble_conn_params_evt_handler_t evt_handler;                      /**< Event handler to be called for handling events in the Battery Service. */
    ble_srv_error_handler_t       error_handler;                    /**< Function to be called in case of an error. */
} ble_conn_params_init_t;

Do I find the right params? Is there any other way to short the time ?
