I am programming with bluez in C, transfering data from a linux PC to a
java application on a phone. All works fine. I have some performance
When I use L2CAP sockets, I get an average of 10% better bitrate on a
given pair PC/phone than with RFCOMM sockets. Also, changing the MTU
of the L2CAP socket has an impact on bitrate. An MTU of 672 on some
phones gives a average bitrate of 190kB/s, nearly 50% more than with
an MTU of 256 bytes.
Also, in noisy environements (with lots and lots of phones with
bluetooth enabled), there is a great decrease in performance (
an average of 50kB/s with a good phone).
What bitrate values can you achieve? Can I expect an amelioration, for
example on fine tuning the stack's parameters, to get the maximum
