Hi,
I'm doing file transfers from my computer to my phone, but I'm not sure
if it's using EDR or not. Is there some way I can find this out by using
f.ex. hcitool, hciconfig or some other tool during the file transfer?
I use obexftp for the file transfer and both ends should support
Bluetooth 2 + EDR.
BTW: where do I find the explanation for the "Features" bytes?
My computer:

my guess is that it is the phone. It still needs a CPU that can handle
these data rates.

OK. Then there is something else wrong - the transfer is very slow. Do
you have any hints or tips for how to debug the problem?

the EDR is activated by default. You actually have to manually
deactivate it.

>>From the Bluetooth specification.
