I am not sure what you mean by "profile".

The bluetooth specification provides numerous profiles e.g. "handsfree
profile", "headset profile", "advanced audio profile" if the hearing and
and phone don't have at lest one profile in common they won't communicate.

Does the hearing aid require e.g. BLE? (bluetooth low energy)

What model is it?

The problem is I do not know enough to answer those questions. Except
the model which is: Phonak Audeo M90.
