Why are there such idiotic smart TVs that can’t even turn off bluetooth?!
There are at least two such devices in my apartment block and my bluetooth audio transmitter always tries to connect to them instead of my headphones. I have already talked to the people owning those TVs and we tried to disable BT, but it just isn’t possible. This is driving me insane!
I’m pretty sure the S-Pen uses some form of low frequency induction. It works for such a use case due to the immediate proximity of the devices, while a TV remote would likely be too far away.
IR can be used to send data. My first laptop had a IR tx/rx. We tried it for fun and it worked.
…okay and? Super or subsonic audio can also be used to transmit data. What’s your point? We’re talking about S-Pens.
