It works only wired with teletype. This keyboard isn’t like the “fake wireless” ones out that have dongles. It’s just Bluetooth normal-style like Apple wireless stuff.
But out of the 2 “wireless” keyboards I tried with tt, both worked (they had usb dongles), so I’m sure others would.
What I do with this one that’s cool tho is I use it wired with the teletype. I can do the quick key combo for Bluetooth on the keyboard (like alt+enter or something), then I’m on my laptop, and I can switch back and forth. So this works well if your teletype is by your computer. Mine isn’t haha. But you could have only one keyboard that way…
