    I am using open obex over bluez stack on linux to push file to a nokia phone.My donle is a usb csr dongle. I programmed followed the test example for pushing files in openobex. But I foud the speed is too slow, about no more than 20kBype/s. If I use the windows or ivt stack for pushing, with same pc and phone, the speed is twice as openobex-about 60-70kByte/s. And the kdebluetooth also use openobex to push, it's as slow as my program-about 15-20kByte/s.

    I wonder is this caused by the bluez stack or due to defect of open obex? Is there any way to improve the speed for obexpush over bluetooth?

      I noticed the same. I can push files more than twice as fast using windows.

    I'm also experiencing the speed problem. I need to send large files to the device using a bash script, but the speed is never higher than 15kb/s. Instead using the gui tool from the Blueman applet 1.10 (Ubuntu 9.10)  the speed achieves 115-120kb/s, but I didn't manage to send files from command line via obex-data-server. :( Is there something I can do to set the speed of data exchange higher?
