Subject: [Bluez-devel] playing with handsfree program

Hi,

I am trying to use handsfree-040326.tar.gz from
http://140.78.95.100/~vogl/bluez/ to emulate a handsfree device with my
computer and BT adapter.
I recompiled the program and tried to execute it but I receive imediately
a:
./handsfree test.wav 00:60:57:80:84:71 12
Voice setting: 0x0060
Can't connect RFCOMM channel: Invalid argument

I think it is because of recent changes in bluez-libs and utilities,
because a " rfcomm connect hci0 MY_BT_ADDR 12 " works just fine.

The problem I think is in rfcomm_connect() function from handsfree.c. I
will try to do more tests, but if somebody has an idea what might be
wrong, I will apreciate a hint.

I copy here the rfcomm_connect() function for readability.

static int rfcomm_connect(bdaddr_t *src, bdaddr_t *dst, uint8_t channel)
{
struct sockaddr_rc addr;
int s;

if ((s = socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)) < 0) {
return -1;
}

memset(&addr, 0, sizeof(addr));
addr.rc_family = AF_BLUETOOTH;
bacpy(&addr.rc_bdaddr, src);
addr.rc_channel = 0;
if (bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
close(s);
return -1;
}

memset(&addr, 0, sizeof(addr));
addr.rc_family = AF_BLUETOOTH;
bacpy(&addr.rc_bdaddr, dst);
addr.rc_channel = channel;
if (connect(s, (struct sockaddr *)&addr, sizeof(addr)) < 0 ){
close(s);
return -1;
}

return s;
}

I am not aware of any change that could cause this error message.

Regards
