We are working fine with most of the phones (e.g. iOS, Android, Blackberry), although we have no exact list of the compatible phones.
Important: The Bluetooth and smartphone world is constantly developing. We follow up the latest changes of these. Therefore if we release a new firmware update version, it mostly contains Bluetooth changes. This also means, that if you have a phone, that uses newer Bluetooth settings, then you will need the latest firmware version - or if your phone uses older Bluetooth settings (no matter if the phone is older or brand new), then an older Gateway firmware version might be needed.
