[Bluez-users] Is Bluetooth 2.0 supported/implimented by bluez ?

[Jerone Young]

I have been trying to transfer files from my cellphone to my computer
over bluetooth quickly. Both are bluetooth 2.0 and I noticed under
linux that they do not transfer at much slower speed then under
windows. After some investigation I have to assume that they are
transfering using bluetooth 1.2 speeds & not bluetooth 2.0 speeds. My
cell phone is a Nokia N73 & usb dongle is belkin bluetooth 2.0 class1
usb dongle. I have tried this with Ubuntu Edgy & Fedora Core 6 using
the gnome file sharing applet on the computer to get the files.

After reading the source code I see the the VHCI is has a decleration
"define VERSION 1.2". Looking at the kernel code & bluez tools it does
not look like bluetooth 2.0 is supported. But I can't find a
definative answer anywhere.  Does anyone have any idea ?

Here is info on my bluetooth dongle:

        Firmware 0.65 / 92

I also went out and got a Bluetake 700sx and still do not get 2.0
speeds..what is going on. It looks like Bluez does not have Bluetooth
2.0 implimented.

both sides has to support EDR packets to achieve Bluetooth 2.0 speed and
BlueZ fully supports EDR and will use it whenever possible.
