Hi,

Sorry about that. The reason: I sent the message to the list, and waited fo=
r=20
it to appear to my mailbox. It didn't appear and then I realised that I am =
not=20
even subscribing the list. I thought that the message didn't get to the lis=
t=20
and I posted it second time.

I have tried to use sendto this way:

int sock;
struct sockaddr_l2 sock_addr;
char addr[18] =3D "00:12:37:46:bc:2b";

sock =3D socket(AF_BLUETOOTH, SOCK_DGRAM, BTPROTO_L2CAP);
sock_addr.l2_family =3D AF_BLUETOOTH;
sock_addr.l2_psm =3D htobs(6001);
str2ba(addr, &sock_addr.l2_bdaddr);
sendto(sock, "Bluetooth test", 15, 0, (struct sockaddr*)&sock_addr, sizeof
(sock_addr));

sendto returns 'Invalid argument' error.

-Ari

the SOCK_DGRAM support in L2CAP is not really good and thus might don't
wanna you sendto() at all. Are there any problems with binding and
connection to an L2CAP channel?
