Android researcher Kuba Wojciechowski has spotted code for a Google first-party Bluetooth tracker codenamed—just in time for The Mandalorian season 3—"Grogu."If you don't want the tracker to play a ringtone to reveal its location, UWB or "Ultra Wide Band" is a radio technology that can physically locate an item.Another interesting wrinkle is that Esper's Mishaal Rahman recently posted about a "locator tag" option landing in Google's Fast Pair developer console.Fast Pair is Google's API for quickly detecting and pairing to nearby Bluetooth devices—it shows a pop-up on the screen rather than making people dig through the settings menu.It suggests that Google is planning to build a Bluetooth tracker ecosystem for Grogu and let third-party hardware join the party."
