Thank you! Joseph

@Joseph: According to the spec of ANCS " the NC (notification consumer) should look for and subscribe to the Service Changed characteristic of the GATT service in order to monitor for the potential publishing and unpublishing of the ANCS at any time."
What it means is the client should enable indication on the service changed characteristic. And it will receive an indication (BLE_GATTC_EVT_HVX event) when there's a service change.
[EDIT] changed from "need to" to "should"
Hello Hung, unfortunately, my work is based on SDK 5.1.0 and s310 v1.0.0, can I use the ble_db_discovery.c library by direct copying from newer SDK? And which SDK I should use? Thanks!
