In simulant+ if you setup in a shifting display and system and then do a datapage request and request acknowledged pages it will send acknowledge pages. This is directly in conflict with the latest version of the profile published (v1.0) it says

A shifting device shall only send broadcast messages to the display, and shall never send acknowledged or burst messages.


Unlike the exception that is listed in the heart rate profile that allows for datapages that have been requested to use ack messages.

Some clarification would be appreciated. Should the system respond with ack messages or not?

The responses should be sent as acknowledged if that is what is requested. However, you should not see requests for acknowledged messages from displays for this profile.
