> As much as I hate on the protocol, the Layer 1 spec is truly ahead of it's time, in some areas. Watching two radios frequency hop, and negotiate to avoid a congested wifi channel was unreal.
What are you using to watch Bluetooth at a low level?
My Magic Mouse at work would get very jerky with my Mac Pro. Resetting it would sometimes clear it up for a while. I swapped it with my Magic Trackpad from home, and the mouse is fine at home, and the trackpad now has the jerkiness although not as much as the mouse did.
I tried moving the Mac up on to the top of the desk so the mouse/trackpad is only a few feet away, and has line of site instead of having a metal desk between it an the computer, but that made no difference.
I'm speculating that it is some kind of interference from the office downstairs. (It's an office of Azima DLI, which develops all kinds of stuff that might be noisy in RF).
I'd like to be able to take a look at what is actually going on in my office (1) with RF in general, and (2) specifically between my Mac and my trackpad or mouse.
I thought this might be an excuse to step up from one of those $15 SDR dongles I've played around with to a HackRF, but from what I've read the HackRF cannot fully deal with the Bluetooth frequency hopping. I think I read that using multiple HackRFs one can do it, but that's beyond what I want to spend.
USB 3.0 devices can interfere with Bluetooth. Do you have any external hard drives in plastic enclosures? Non-shielded cables?
USB 2.0 doesn't present this kind of problem.
