Hi guys,
I am working on BlueZ for a few days now and it is hard to start working with it for me. I want to write a program (Client/Server) in C which uses the rfcomm socket and I want to use a channel to transfer data between these two computers.
The HCI_inquiry function is running and finds the other PC. How can I establish a connection between these two computers with the rfcomm sockets?
Thanks for helping
Bj?rn
THX Lars,
I also found some stuff in rctest.c . I will have a go with that,too.
Cheers
Bj?rn

have a look at the example programs. it should be something like:
(this is for connection to a headset with rfcomm, but it should be
similar. There are other examples in bluez-tools, if I'm not mistaken.
static int rfcomm_connect(bdaddr_t * src, bdaddr_t * dst, uint8_t channel=
)
{
~ struct sockaddr_rc addr;
~ int s;
~ if ((s =3D socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)) < =
0) {
~ return -1;
~ }
~ memset(&addr, 0, sizeof(addr));
~ addr.rc_family =3D AF_BLUETOOTH;
~ bacpy(&addr.rc_bdaddr, src);
~ addr.rc_channel =3D 0;
~ if (bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
~ close(s);
~ return -1;
~ }
~ memset(&addr, 0, sizeof(addr));
~ addr.rc_family =3D AF_BLUETOOTH;
~ bacpy(&addr.rc_bdaddr, dst);
~ addr.rc_channel =3D channel;
~ if (connect(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
~ close(s);
~ return -1;
~ }
~ return s;
}
have fun,
~ Lars
