How can the central be notified for more than one characteristic change by peripheral?

[nordicdev]

Hi, I am using ble_app_uart_c code for central and ble_app_uart code for the peripheral. I am using around 4 characteristics in the NUS service. In the ble_nus_c_evt_handler, once BLE_NUS_C_EVT_DISCOVERY_COMPLETE event is got, ble_nus_c_rx_notif_enable is called to get the central to be notified whenever a characteristic has been updated. How to modify the ble_nus_c_rx_notif_enable so that the central gets notified whenever ANY/ALL of the 4 characteristics are updated by the peripheral?

Have you modifed the central application at all? What SDK and SoftDevice are you using?
