Bluetooth speed

[Guest bharat4ever]

Hi guys,

I've asked this question on a number of other forums also, no one seems to know the answer...

I'm trying to transfer a 5 MB file from my X1 to a W810i, and the maximum speed I get is 20 kBps. Whereas when i transfer from my K850i to the same W810i, i get 40kBps. Is there something i am missing out in the bluetooth settings for the X1? or is this the max speed?

Please help me...
