This entry is a year old, so this may not be helpful at this point, but the "Missing entitlement for API" error most commonly happens when trying to communicate with a device when the app is in the background, which unfortunately is not allowed (I would love it to be allowed, even in some limited way -- Apple, please?). Is this when you're seeing it, or is it happening while the App is in the foreground?
