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

this is how it should be. I fixed the kernel code to prevent creating
connections with the SOCK_RAW interface.
Regards
Marcel

is there as way to set a timetout to a socket??=20
what i mean is, if the socket does not read anything for certain time, the =
read=20
operation would unlock and the execution of the program continues. is
there a way to
accomplish this??

now it works with SOCK_STREAM, and i havent changed anythig to the
program. i realy don't understand how this could be. I'm using kernel
2.6.12-CK and the bluez libs version 2.19?

this is wrong and if this works it is a bug inside the kernel. Why don't
you run "hcidump -X -V" as I told you?

i tried your changes but it didn't help. i thank anyway for your help
i solved my problem at least for now. I've changed SOCK_STREAM to

the rfcommX devices are optional. They must be created with a special
ioctl() after you established the connection. However most applications
don't need a TTY. They work perfect through a socket.

the htobs() is wrong here. The channel is uint8 value and thus a endian
change is not needed.

Run "hcidump -X -V" to see what happens. Run "sdptool browse local" to
see what channel is advertised for your serial port service.

I also notice now, that I don't have any /dev/rfcomm* or
/dev/bluetooth/rfcomm* devices under /dev. I'm using udev as a device
manager. anyone?? please
