How Many Wireless Controllers Can I Connect?

Hi. Sorry if this is the wrong part of the forum to post. I’ve searched and can’t find any answers. I have a Wetek Hub and I’d like to try 2 player gaming (both wireless if possible) but I don’t want to buy 2 wireless controllers if I can’t be sure that both can connect simultaneously for gaming. Can anyone please shed some light?

Is it possible to use 2 wireless controllers via bluetooth? What’s the max? Does it depend on what hardware you’re using? Thank you!

I’m using 4 controllers. But I’m sure you can connect more.
