Information about status of AMP controller does not depend on > A2MP connection. the only part using this information will be A2MP and it has to read it from the controller fresh almost every time. So yes, it belongs there and not inside HCI. At least that is how I read the AMP controller specification and how it is suppose to be used. > > I think these definition can stay local in net/bluetooth/a2mp.c for now. > > maybe a2mp.h then? As we use existing HCI command infrastructure to handle > AMP specific HCI commands we might need to source the header. As I said, leave it local for now. We can always move them around later.
