Just to clarify further.
AppRF 1.0 is available on 3200XM, 3400, 3600, M3 and 7200 series platforms. You can see this in AOS 6.3.1.0 or higher release notes.
Future versions of AppRF may have additional hardware requirements which could mean they cannot be supported on certain platforms and will be documented accordingly when that new feature is released.
Best regards,
