Just had a few minutes today to run a quick test on two bluetooth cards that I have. Was primary interested in max up/down-stream throughput, so didn\'t mesure latency. One end was a Zaurus 5500 running latest BlueZ as a panu client, the other end - Win2K running Bluesoeil 1.4.2 with CSR usb dongle. Z was connected via BNEP to Bluesoeil NAP profile. I was transferring a 0.3MB file via tftp (tftp has low protocol overhead), and measuring transfer speed. Filesystem cache didn\'t play much role in this scenario, only raw network link bandwidth. All the conditions were the same for all test runs. Here\'s the results:
Card Driver In/Downstream, B/s Out/Upstream, B/s
==== ====== ================== =================
Socket Rev.F dtl1_cs 11,059 9,714
BT2000E bt2000e_cs 8,167 11,333
BT2000E bt950_cs 8,045 10,950
Quite interesting, isn\'t it?
One subjective observation - during transmission, both Socket and BT2000E with bt2000e_cs driver were demonstrating consistent throughput, while BT2000E with bt950_cs driver was jumping up and down quite a bit. There were no errors reported by either side during transmissions. Socket rev.F card uses Nokia bluetooth module, while BT2000E uses Ericsson\'s. Too bad I didn\'t have a CSR-based card to fire up against Nokia and Ericsson.
Well, that\'s all I have to say, folks. Sorry, was very limited in time, so not much testing.
Anton, if you\'d like to conduct more testing, please share results, I would be interested to see...
