(1) Will Apple OS be a regular, full-featured SmartSDR v2 release?
(2) Will the Mac release fully support DAX and CAT?
(3) Will there be a fully defined Ethernet API documentation?
I left with the understanding that DogparkSDR remains the Apple OS partner product. There wasn't any mention of a change.
Previously discussed FRS said the DAX/CAT components do not have direct equivalents in the Apple OS world, nor does DDUtil. There have been some threads on how to manage some of the aspects of Apple's audio.
Not certain what you've meant by the Ethernet question, as the API interface for the radio-server is well defined.
I've been working to develop a Mac-native version of the FlexAPI. I also know of a Mac DAX and CAT equivalent in the works. Hopefully some of these will be ready for use soon. DogPark or SmartSDR for iOS together with a Mac-native DAX and CAT and some of the other Mac software already available will allow you to turn off the Windows box (if that's what you want).
As far as API documentation goes, I would agree that there is a good deal of documentation already but it's not 100% complete and not in an easily digestible form. I also find it difficult to understand the exact sequence of events and the timing of commands and responses. Wireshark is helpful for this but has a fairly steep learning curve.
I've built a simple Mac program to allow me to send and receive commands to / from the Radio, it has helped me to understand the API. I'll make it available as soon as I finish debugging my API code.
