That's to say, the tech to use bluetooth to "scan" someone's thoughts exists. A lot of bt earbuds can already do it - especially ones like Air Pods or whatever the Samsung proprietary ones are. They could just be using this advertiser method to test and refine the new algo.

I have no citeable source, no hard proof... But, it's a thing.
