Hi Julien and Marcel,

When I execute 2 servers on masters side (one only sending and the other =
only
receiving) using diferents rfcomm channels, I also receive corrupt data (=
very
rarely :-( ). If they're both sending or receiving, everything works fine=
... I
think it's possible to use semaphores to synchronize the 2 processes but =
I'd
like to use a simpler solution or at least understand where the problem i=
s.

Regards

Didier
