I have just got Bluetooth working on my Thinkpad (Debian Testing/Squeeze) and it will pair with my Android 'phone but the signal keeps fluctuating. The link quality between 100% and -1%, the strength between 58% and -1 and it does this at around 2-5 second intervals.
It does it even when the 'phone is next to the laptop. Can anyone suggest a reason for this?
No idea if they're any good, but I can suggest two:
interference from another badly-behaved Bluetooth device nearby;
some incompatibility between the implementations.
I think there's something you can install on a Debian system to dump the bluetooth traffic in copious detail, but I don't remember its name. Then you can try to compare an example working session with what your devices are doing.
Is performance actually impacted? What's reporting the link quality? Could it be a buggy reporting routine? (Wasn't the iphone's signal strength partly a buggy reporting routing?)
Hope that helps,

Thanks for offering those suggestions.
1. There is, as far as I'm aware, no other Bluetooth devices in range.
2. Signal details are being reported by Blueman-Manager. I have tried it with the version of Windows XP that came with the laptop and I can connect to the 'phone and send a file to it. During this process a window pops up on the 'phone asking if I want to recieve the file. I get no such response when using Debian/Blueman so I assume the 'phone isn't recieving a request it can understand or not recieving the request at all.
As far as performance being impacted as I can't do anything with it yet there is no performance. :-)) To avoid any misunderstanding - it's an Android 'phone not an iPhone.
