Hi list.

I am tryint to get the maximum throughput using 2.0 dongles (anycom
USB-250). For my tests I wrote a program that opens a l2cap socket with a
second host and continuously writes a message of 1200 bytes. Befores opening
the socket connection I change the connection packet type to 3-DH5 with
hcitool utility. My kernel is 2.6.22-rc6 and I have just installed
bluez-utils-3.12 and bluez-libs-3.12.

I thought this environment would be enough for getting close to 3Mb/s of
transfering throughput, but I am just reaching a little over 1 Mb/s.

Does anyone ever tried something similar? Can anyone give some direction
about what I am missing?

Thanks in advance!

Loreno
