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:
