[Bluez-users] L2CAP MTU and packet fragmentation?

[Stephen Strowes <sds@dcs.gla.ac.uk>]

Hi,

Forgive me if this has been answered time and again, but I can't seem to
access the archives just now. Google's not helping me much either.

I have a bit of BlueZ code, which I have to make use of L2CAP sockets to
communicate between devices. I've seen that I can alter the MTU for
packets, but I'm surprised that packets don't get fragmented as per
plain UDP when a packet larger than the MTU is passed to send().

Have I missed a configuration option somewhere?

I could live with the MTU being 64k with no fragmentation, but I seem to
get quite a lot of corrupt packets over around 2kB.


Cheers,
Stephen.
