I did look, back when, but it’s been a few years, since I wrote that, and it hasn’t really been a priority. When I was writing it, I spent a lot of time with a sniffer and WireShark, so I was looking at the raw data. [EDITED TO ADD] Sniffers are of minimal use, with BLE, since everything gets encrypted, as soon as devices start talking to each other, but you can see the advertisements. I used one, because all the Apple devices seem to have a different opinion, on what's out there. I'd see a device with the Watch, but not the phone or TV, and vice-versa. I actually submitted a bug report on it, but I don't think Apple ever even looked at it. I'm sure they are well aware of this. I suspect the Apple engineers are probably some of the top BT people in the world.
