Core spec V5.4 Vol. 3 Part G 2.5.2.1 Robust Caching specifies
the conditions where Database Out Of Sync (0x12) error needs to
be returned as follows:
If a client that has indicated support for robust caching (by
setting the Robust Caching bit in the Client Supported Features
characteristic) is change-unaware then the server shall send an
ATT_ERROR_RSP PDU with the Error Code parameter set to Database
Out Of Sync (0x12) when either of the following happen:
• That client requests an operation at any Attribute Handle or
list of Attribute Handles by sending an ATT request.
• That client sends an ATT_READ_BY_TYPE_REQ PDU with Attribute
Type other than «Include» or «Characteristic» and an Attribute
Handle range other than 0x0001 to 0xFFFF.
Add the conditions to ATT_READ_BY_TYPE_REQ handler.
