BNEP and Raw Ethernet Sockets

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,

This document is outdated, bluetoothd should be able to handle devices
with PAN profile, pand is deprecated.
