Weird Bluetooth Behaviour, Transfer Rates

[kuru]

So I received my bluetooth stuff from amazon today.
hama nano dongle class 1
hama dongle class 2

Pairing with both n95 and stowaway keyboard works fine. Software is blueSoleil where each of the dongles' boxes contained one CD of.
Apparently the Software recognizes what stick it should be used with/was bundled with. So I have to install both to test both sticks -_-
Nevertheless I did some speed tests pushing a 50MB ISO to my N95. The class one dongle hit about 120kByte per second, while the class 2
which I intended for Laptop use due lower power consumption reached about half of that, merely stable 50kB a second.
Edit: class 2 dongle is 2.0 w/EDR, class 1 is 2.1 w/EDR

And then I was in for a surprise: I paired up my stowaway while still transferring data and let one finger rest on one of its function buttons.
As my gaze swept over the transfer speed indicator I saw the class 2w dongle reached the same speed as the other one!

Letting go of the keyboard would return the speed to normal! Near the end I got an error saying the file could not be copied, dunno if I have
affected that or something else messed it up.

SO, this is weird. Why does bluetooth act like that?




(could someone please add another U to that description, kthx)

It was in fact the iso of that bluetooth software, which I ripped at work because my fancy can-do-it-all
burner wouldn't read those mini CDs. A crappy notebook's drive did the trick.

Still puzzling though. They should have the same data rate, only differ in range.

Actually I can think of something, but that makes onyl half sense. Maybe it'-s reserving bandwidth for a second device (which would be stupid when there's only one connected) and when the 2nd uses is connection it notices the unused bandwidth and grabs it.
