So this would be the brute force solution for people who are running their Bluetooth speakers on full blast in public spaces.
mfkp•2h ago
Would potentially be useful when walking through grocery stores etc. that track your precise location and shopping habits through bluetooth beacons.

Or just leave your phone in the car and pay with cash...

yjftsjthsd-h•1h ago
Or... Turn off Bluetooth on your device?
mfkp•1h ago
If you trust that it's really off. Not sure if it's still the case but see: https://news.ycombinator.com/item?id=22856030

> This can be completely turned off in scanning settings. The article title is kind of clickbaity.

Okay, one extra setting and you're good. (Yes, that's not great, but if it works then it works)

These are illegal in most countries.

As noted in all-caps with exclamation mark, right at the top.

That's the loudest readme I've read in a while, every other sentence ends in an exclamation mark!

I wish these were legal. I do a lot of hiking in forest/mountain trails and it gets SUPER old having someone going along the trail bumping some loud music on a big Bluetooth speaker in their bag. Like, really? Get some earbuds and cut that shit out please. I came to nature to be in nature, not to listen to the latest hardstyle tracks emanating from some dude's backpack. I don't really see why I shouldn't be able to RF jam that shit since they're apparently allowed to jam my earbuds with their acoustic interference.
