we are facing some issues concerning QOS requirements on a l2cap connection.

 Does Bluez fully support QOS  because in the setsockopt method or 
getsockopt
 method, there's no QOS values to fill or retrieve ..

 When the connection has been completed ,  we use the
 hci_send_request(..OGF_LINK_POLICY, OCF_QOS_SETUP....) primitives but we 
get
 "protocol not available 92" error    with CSR class 1 and Broadcom class 1 
USB dongles ?


 Here is the code in our L2CAP  listening method  once the connection has
 occured  and the socket already created

WORD handle = 0;
struct l2cap_conninfo info;
int infoSize = sizeof(info);
if( getsockopt(my_connect_socket, SOL_L2CAP, L2CAP_CONNINFO, &info,
(socklen_t*)&infoSize) < 0 ) {
printf("Can't get L2CAP options. %s(%d)", strerror(errno), errno); return
false;
}
 handle = info.hci_handle;
 qos_setup_cp qosSetupParams;
 qosSetupParams.handle = handle;
 qosSetupParams.flags = 0;                          /* Reserved */
 qosSetupParams.qos.service_type = 0x02;            /* Guaranteed */
 qosSetupParams.qos.token_rate = 0x00004250;        /* 32kbps + overhead */
 qosSetupParams.qos.peak_bandwidth = 0xFFFFFFFF;    /* Unspecified bwdth */
 qosSetupParams.qos.latency = 4000;                 /* In microseconds */
 qosSetupParams.qos.delay_variation = 0xFFFFFFFF;   /* Do not care */

 struct hci_request request;
 request.ogf = OGF_LINK_POLICY;
 request.ocf = OCF_QOS_SETUP;
 request.cparam = &qosSetupParams;
 request.clen = QOS_SETUP_CP_SIZE;
 if (hci_send_reqmy_connect_socket, &request, 1000) < 0) {
  printf("Can't set QoS on connection. %s(%d)\n", strerror(errno), errno);
 }

 printf("CBluetooth_Socket: connect() succeeded\n");
 return true;
