Bluetooth LE advertising support

We are working on enabling BLE GATT Server on SabreSd board and we are acing following issue:

On Android Layer it is throwing the error as

E BluetoothAdapter: Bluetooth LE advertising not supported

When we debugged further we found that inside a callback function
static void btm_ble_vendor_capability_vsc_cmpl_cback (tBTM_VSC_CMPL *p_vcs_cplt_params)

'status' is HCI_ERR_ILLEGAL_COMMAND which supposed to be HCI_SUCCESS in true scenario.

This callback function is returned when inside BTM_BleReadControllerFeatures(tBTM_BLE_CTRL_FEATURES_CBACK *p_vsc_cback)

we call

BTM_VendorSpecificCommand (HCI_BLE_VENDOR_CAP_OCF, 0, NULL,btm_ble_vendor_capability_vsc_cmpl_cback).

Here HCI_BLE_VENDOR_CAP_OCF is defined as:

:#define HCI_BLE_VENDOR_CAP_OCF (0x0153 | HCI_GRP_VENDOR_SPECIFIC)

#define HCI_GRP_VENDOR_SPECIFIC (0x3F << 10) /* 0xFC00 */

1) What could be the reason for this error ?

2) Is HCI_BLE_VENDOR_CAP_OCF vendor specific ? Do all vendors support this values or they are only meant for broadcom?
