As it's 2.4ghz it may also be partially spectrum pollution. That said - that seems rather impressive for Bluetooth, I've had one reinforced concrete wall pretty consistently screw up most bluetooth signals in my experience, so I'd posit that you're getting unusually good reception there.

I wonder what strength the radios broadcast on. I do have a 2.4GHz wifi-router both downstairs and in the attic so you would expect no signal at all, given the situation. I'll admit that by this point it's extremely sensitive to spectrum pollution; a nearby laptop with wifi on will mess with it enough that it starts stuttering. My only issue with bluetooth is with Android; it semi-randomly likes to change pitch and s…

I could not care less. - 1.0 to 1.2: Hard to pair, and very unreliable. First major version, I'm sure they'll fix it... - 2.0: More bandwidth. Still hard to pair, still unreliable. - 2.1: Adds "Simple Secure Pairing". Still hard to actually pair. Still unreliable. - 3.0: More bandwidth. More features. Still hard to pair, still unreliable. - 4.0: Bluetooth Low Energy released. Still hard to pair, still unreliable. - 4…

That's weird, I have a Pebble and the bluetooth is absolutely solid, even across my house. I've never had a good experience with desktops and bluetooth devices however. I wonder why drivers are so much better on mobile?

Could be that it's not the sun being the problem, but not having walls. Inside, the radio waves can bounce of the walls, around your body. Outside, they have to go through your body.
