Thanks hammer22. So in short the module won't really have a workable model memory which was expected, it will send the same GUID to every RX you bind with. If you press that button you will probably get a new GUID and have to rebind all your stuff. I don't get this obsession with model memory anyways. It's a "nice to have" but by no means is it needed.
