Bluetooth Part 2

[Anonymouse]

I have 2 sets of Sony Ult Wear headphones - 2 so I can use one while the other's on charge, thus I never have to stop using them.

At least, that was the idea. But one set not only won't connect, Windows can't even find them. It did at one point, found both, as did Linux - but somehow, I can't remember how, I lost one - and now neither can find that set.

However, I've confirmed there's nothing wrong with either set...because my tablet found both with no problem. The one which works is 40:72:18:F5:B2:58, the other one is 40:72:18:69:89:4E. Question: if you know a device's MAC address, is there a way to force Bluetooth to connect to it?

I've updated to 24.01 (or whatever the number is). Still no joy.

Linux can't find it either. It finds my tablet, finds a car thing, but Ult Wear Headset? Zilch. Not a power problem either; it says the battery is fully charged. Plenty of unnamed devices, none with the correct MAC, so it's not finding it but failing to ID it. It's just not finding it at all. Why?! All you do with the Ult Wear - all you can do - is turn it on, and it's discoverable!

(In theory.)
Hmm. Progress, of a sort; bluetoothctl on Linux reports the device isn't available. Again, WHY?! What am I missing?!
