Hi,

does the dynamic rfcomm channel allocation work? I'm running 2.6.7-mh1
and I allways get channel 1, which is used (listend and connected) by a
other process. I don't get any error it just binds and listens on
channel 1.

cat /proc/bluetooth/rfcomm/sock 

/* created thru: rfcomm listen /dev/rfcomm0 1 */
00:00:00:00:00:00 00:00:00:00:00:00 4 1
00:00:00:00:00:00 00:00:00:00:00:00 2 0
/* created thru: running my server */
xx:xx:xx:xx:xx:xx 00:00:00:00:00:00 4 1

my code:

server_sa.rc_family = AF_BLUETOOTH;
server_sa.rc_channel = channel;		
server_sa.rc_bdaddr = self.addr;

if (bind(server, (struct sockaddr*) &server_sa, sizeof(server_sa)) < 0){
 return(-1);
}
		
if (listen(server, 1) < 0) {
 return(-1);
}
	
if (channel == 0) {
 remote_len = sizeof(struct sockaddr_rc);
 memset(&remote_sa, 0, sizeof(struct sockaddr_rc));
 if (getsockname(server, (struct sockaddr*) &remote_sa, &remote_len) <
	0) {
  return(-1);
 }

 channel = remote_sa.rc_channel;
 printf("bt_server(): channel %d\n", remote_sa.rc_channel);		}
			
thanks ... Collin
