Hellow all.
I`m try to write application that send and recive data over L2CAP channel, between PC and my custom arm board. I have a next problem. I dont understand haw create a socket, if PC must inquirying and connect to my board. Device must remain slave in piconnect.
I`m try run next simpl daemon on my custom arm board:
struct sockaddr_l2 L2capAddr;
int iSockFd;
iSockFd = socket(PF_BLUETOOTH, SOCK_RAW, BTPROTO_L2CAP);
if (iSockFd == -1) {
TRACE1("opening L2CAP socket: %s", strerror(errno));
return -1;
};
L2capAddr.l2_bdaddr = *BDADDR_ANY;
/*L2capAddr.l2_bdaddr = *strtoba( strdup("78:A1:1F:96:A0:00"));*/
L2capAddr.l2_family = AF_BLUETOOTH;
L2capAddr.l2_psm = htobs(SDP_PSM); // I sigth this valuer in Tsimbal code
if(0 > bind(iSockFd, (struct sockaddr *)&L2capAddr, sizeof(L2capAddr)))
{
TRACE1("binding L2CAP socket: %s", strerror(errno));
return -1;
}
incoming = listen(iSockFd, ACTIVE_CONN_MAX);
But ACL connection don`t establishing. The hcidump on board give next chat

Try replacing SOCK_RAW with SOCK_SEQPACKET. SOCK_RAW is only for raw HCI
sockets.

what about using "hcidump -X -V", because I am no longer decoding hex
