BNEP and Raw Ethernet Sockets

Hello,

    I've been trying for a while to make a BNEP network exchange
messages through raw ethernet sockets, but up to now I could not come
with a reasonable explanation of why it is not working. I have done
the following experiments:

1) Build the network according to the BlueZ PAN Howto
(http://bluez.sourceforge.net/contrib/HOWTO-PAN), consisting of 2
nodes, then 3 nodes with bridging.

2) Tested simple UDP broadcasts: worked fine, everyone receives the packet.

3) Tested with Raw Ethernet sockets: Source Node sends, but the frame
simply doesnt seem to reach the destinations (it is also a broadcast,
but a link-layer one).

    The codes I have been testing are attached, if anyone has
experienced the same situation and found a solution, or if anyone is
suspicious about what might be happening, I'd be glad to hear.

    My main suspect is that hand-made Ethernet frames are not what the
BNEP layer is expecting (and thus I see some errors in Wireshark), but
then, what is it that BNEP expects?


best regards,
