I've got a Logitech K400+ wireless keyboard that came with a tiny USB stick that can hardly be even called a stick, because it sticks out only about 1/4" from the USB connector. This supposedly makes this a USB keyboard. What I don't find anywhere is what kind of wireless connection is used between that USB stick and the keyboard itself. Is it Bluetooth, WiFi, or some kind of proprietary radio link. The reason is that I'd like to use this keyboard also as an external wireless keyboard for my Samsung QLED smart TV that accepts WiFi or BT external devices but I don't see how I could also use that USB stick with it.
