[Bluez-users] rfcomm sockets problems

[Paolino paperino <vonzoltan@yahoo.it>]

Hi,
I've used the test program rctest to test the
capability of open a connection between two linux
boxes with bt. Well the protocol seems (l2test) to be
instable, when i transmit  a sequence of packets
composed of only 1 bytes, the reader loose some
packets. The command lines i use are:
rctest -s -b 1 -N 1024 <addr> (sender, client)
and
rctest -d -b 1 (receiver, server)

I see the source code and i put an usleep pause after
the send call in the function void send_mode(int
s)...with this pause all seems work, but when i try to
send packet bigger than 1019 bytes other problem
arises, for example if i send a packet of 1024 bytes
then the packet will be braked in two packets, one of
1019 e the other of 5. In the case i send many packets
bigger than 1019, some data is lost, the receiver
receive less bytes of what are sended.

rfcomm socket must be realiable sequence stream, but
is not so, i can't understand where is the problem, if
mine or Bluez stack's.
Anybody could tell me if he had the same problems!!
I use Fedora Core 2, kernel  2.6.8-1.521 and bluez
libs/utils 2.8.

Thanks
Regards
 Andrea S.
