hi Robert,
                I have had similar experience too .. I want to add one more
point :-

There is a difference in transfer rates while transfer a file between phone
and PC between when i am simply making obex push of the file and when i am
transferring files after pairing up the device.

Is the above behavior expected. I feel that this should happen but a
confirmation from more experienced people will give more confidence.

regards
siddhant

<div>Hello Guys,<br>
&nbsp;<br>
I&#39;m running Bluez 3.12 and doing a little bit of file transfer over OBEX push and seem to get considerably lower transmission speeds than when i&#39;m transmitting from my windows system using the windows stack. For instance, when transmitting a 40kb file from my linux system using bluez the file will take several seconds to transfer from acceptance of the invitation, however, when using the same hardware on my windows box, it will transfer almost immediately, with no noticeable delay, this speed difference becomes even more apparent when dealing with larger files.
<br>
&nbsp;<br>
I&#39;m sure i&#39;ve read in the past this is quite common when&nbsp;using the linux stacks, is that right? is there any way to make a marked improvement? I&#39;m running bluetooth 2 with EDR capabilities, on a CSR chip.<br>

&nbsp;<br>
Thanks guys,<br>
&nbsp;<br>
