Hi,
I want to run a small rfcomm server, however it does not block on
accept, and returns immediately with -1 as socket descriptor (last
line prints -1 right away).
I have the following code:
// allocate socket
s =3D socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
// bind socket to port 1 of the first available
// local bluetooth adapter
loc_addr.rc_family =3D AF_BLUETOOTH;
loc_addr.rc_bdaddr =3D *BDADDR_ANY;
loc_addr.rc_channel =3D (uint8_t) 1;
bind(s, (struct sockaddr *)&loc_addr, sizeof(loc_addr));
// put socket into listening mode
listen(s, 1);
// accept one connection
client =3D accept(s, (struct sockaddr *)&rem_addr, &opt);
printf("client: %d \n", client);
I expected it would block on accept function until a connection
request came in. I appreciate any comments.
Thanks,
Deniz

Thanks Albert.
It was conflicting port assigment. In fact, I had changed the port,
however, I mistyped in one place. Anyway, it is okay now.

one of the other socket functions probably failed. check the return codes
for all socket calls (a good practice in general) and use perror again. You
may also want to read through that entire guide if you're not familiar with
socket programming.

Use perror to find out what went wrong.
