The other quickly performs discovery using LIAC, and will see only the devices that are currently discoverable using LIAC (i.e., they won’t see the printers, but they might see another person starting a game at the next table too).

I’m new to Bluetooth myself, but I’ve got plenty of reference material and some pretty good experts to help me get up to speed and check what I write.
