I actually had the reverse problem: some stupid neighbor kept trying to pair something with my smart TV, to the point where I couldn’t watch TV at times, due to this moron’s insistence. I looked in the settings and also found I couldn’t disable Bluetooth, or blacklist devices, so I thought of a simple solution: changing the TV name to “virus”. From that day on, no one tried to pair anything with my TV.
No amount of money can save them from the rising sea levels.
