[Bluez-devel] Raw Sockets

[Bluez-devel] Raw Sockets

[Nuno Gomes]

Hello,
I'm writting from Portugal and I'm developing an application with
bluez. This application's objective is to develop an program to
receive data from several bluetooth devices and create a Data Base
with that information. I need to use Raw Sockets, so I can create
specific headers for the bluetooth packets.

Rigth now I'm having some problems using this raw sockets... So, I
have some questions...
1 - How can I capture bluetooth packets using Raw Sockets?
2 - What kind of structure do I need to use to manage the packets (in
sockets tcp/ip we use specific structures to receive/send packets)
3 - Can I capture all the packets or just the packets sent to my
bluetooth device??


Thank You all for the help...=20

what makes you think that you need raw sockets. I don't see any need for
it. Write a client/server application that communicates over L2CAP or
RFCOMM.

Rigth now I'm having some problems using this raw sockets... So, I
have some questions...
1 - How can I capture bluetooth packets using Raw Sockets?
    I'm declaring sockets like this: socket(AF_BLUETOOTH, SOCK_RAW, BTPROTO=
_HCI)
    Should it be diferent???
2 - What kind of structure do I need to use to manage the packets (in
sockets tcp/ip we use specific structures to receive/send packets with
the libpcap)
3 - Can I use read and write structures to send and receive the packets??

Thats all for now...=20
Thank You all for the help...

why do you resend your question? I already answered your first one.
