A client must enable indications on the corresponding CCCD for this characteristic before doing anything else, so that it can become aware of any changes on the server’s attribute structure.

If the server suffers a structural change in attribute layout, it will then immediately send a handle value indication to the client and wait for the corresponding confirmation. In this way, it can be sure that the client understands that cached attribute handles in that range might no longer be valid. If the attributes change outside the lifetime of a connection with a bonded device, the server will send the indication right after the connection is set up, so that the client has a chance to rediscover the affected area.
