Well, I’m not 100% certain on that yet however I can say that Jessie does support much more Wi-Fi / Bluetooth dongles out of the box than wheezy did. I am presuming that the Pi3 built in Wi-Fi and bt must work flawlessly but I can’t test anything until I have finished building NOOBS. :s Can’t believe how long it is taking for such a small file size but I guess there is a ton of code involved.
Ok that’s good to know about Jessie. These things are extremely time consuming. Good luck, I know it will turn out great.
