[Bluez-devel] help needed with rfcomm

[Rui Silva <rukinhas@gmail.com>]

hello ppl,=20

i tried to post these doubts under the bluez-users mailing list, but i
did'nt have any response, and since it has a programing doubt, i'll
try to explain my problem.

i want to buil an aplication that listen on rfcomm bluetooth sockets
and the same aplication receives information thru that socket. i kinda
have a squeleton of the program as folows:


        // cria o socket
        if( (sock =3D socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM))
< 0){
        perror("socket");
        return(-1);
        }

        // op=E7=F5es do socket
        addr.rc_family =3D AF_BLUETOOTH;
        str2ba(argv[1],&addr.rc_bdaddr);
        addr.rc_channel =3D htobs(CHANNEL);
        alen =3D sizeof(addr);

        //regista o socket no SO
        if(bind(sock, (struct sockaddr *)&addr, alen) < 0){
                perror("bind");
                return(-1);
        }
        //poe o socket =E0 escuta
        listen(sock,QUEUE);

        printf("Waiting for connections...\n\n");

        while (1){
                while((client =3D accept(sock, (struct sockaddr *)&addr,
&alen)) !=3D -1){
                        printf("Got a connection attempt!\n");

                        memset(buffer, 0, TAM_BUFFER);

                        if ( (r =3D read(client, buffer, TAM_BUFFER)) < 0
 ){
                                perror("Read no server");
                        }

but i can't get the connections to this computer to work. a i don't know wh=
y.

another problem that i had was that the SPP profile has not
advertized, and i solved that problem by performing a "sdptool add
SP".

anyway, with or without my program, i can't get the computer to accept
the connection attemps from other computers. these connections are
made using rfcomm on channel 1, and i can't change that.
my kernel was all the bluez stuff compiled in, not as modules.=20

any sugestions will be apreciated

so any ideia on how to solve this problem. I lacking time to
accomplish this program so i would really aprecciate all the hep that
you can give me..

thank you all  very much
