And could you tell me why not, what's prevent this to do?
I think the sources are available for CM11, also for the CM11 versions where it's still available.
Is it technically not possible to check the code in the C11 code with implemented ANT+ stack and add it to the satsuma source and compile it back?
there isn't source code available to support our hardware. Other cm11 roms for other phones could be working, but they have different hardware too
