Hi Sun,

It's called. You can find we called service_change_indicate(); in BLE_GAP_EVT_CONN_SEC_UPDATE event in on_ble_evt() in dfu_transport_ble.c.

Basically we will send service changed indication after the link is re-encrypted. In service_change_indicate() we tried to re-establish the system attribute (the CCCD values) before we send the indication.

Note that you need to make sure you set IS_SRVC_CHANGED_CHARACT_PRESENT to 1

Thanks. I find service_change_indicate() is called in LE_GAP_EVT_CONN_SEC_UPDATE event. IS_SRVC_CHANGED_CHARACT_PRESENT is already set to 1.
