Or this:

Then no, that's not yet implemented. Since there are a lot of people eagerly waiting for it, including the famous "elites", I'm sure one of these days a notification will pop up somewhere telling us that it's finally here 😉

As far as this goes:

You can disable the WiFi using code, but still let the Core run. This way, power is reduced, but data can be transmitted if your code deems it nescesarry (it's nescesarry it you program it to be...). Then again, it seems as if you already knew that 😉

Let's hope it's released rather sooner then later!
