I want to know the same about other APIs and events.
The answer I expect is that an event always occurs even when normal or abnormal.

In your case:

When there is no response “ATT Read By Type Response” or “ATT Error Response: Attribute Not Found”, it seems that “BLE_GATTC_EVT_CHAR_DISC_RSP” does not occur.
Is there such a case?
