CC2564MODNEM: GAP_LE_Perform_Scan() with a CC2564MODNEM and a STM3240G-EVAL board

Hi Jo,

Starting from the AUDDemo (available in the CC256XSTBTBLESW software package) I've added an A2DP source profile in order to make an A2DP repeater. It now works as a charm.

Glad to know that your A2DP repeater is working fine.

Now I have to perform a scan of LE beacon device on this same CC2564MODNEM but when I call GAP_LE_Perform_Scan() it returns me a BTPS_ERROR_LOCAL_CONTROLLER_DOES_NOT_SUPPORT_LE (-104).

I thought the CC2564MODN on the CC2564MODNEM board has Dual-mode Bluetooth support, so where am I wrong ?

In addition to the Bluetooth classic (BR/EDR), the CC2564x devices can either have simultaneous BLE operation or the assisted audio/voice features (AVPR). To enable either of these options, their respective add-ons (either BLE or AVPR add-on) must be loaded on to the CC2564x device after downloading the main service-pack.

The AUDDemo, by default, does not enable either of these features because neither BLE nor AVPR is needed for the unassisted A2DP use-case. In order to enable BLE, you will need to call the BSC_EnableFeature API during application initialization. 

For example:

static int OpenStack(HCI_DriverInformation_t *HCI_DriverInformation, BTPS_Initialization_t *BTPS_Initialization)
{
...
        /* Initialize the Stack                                        */
        Result = BSC_Initialize(HCI_DriverInformation, 0);

        /* Next, check the return value of the initialization to see   */
        /* if it was successful.                                       */
        if(Result > 0)
        {
            /* The Stack was initialized successfully, inform the user  */
            /* and set the return value of the initialization function  */
            /* to the Bluetooth Stack ID.                               */
            BluetoothStackID = Result;
            Display(("Bluetooth Stack ID: %d\r\n", BluetoothStackID));
            /* Attempt to enable the Low Energy feature.                */
            Result = BSC_EnableFeature(BluetoothStackID, BSC_FEATURE_BLUETOOTH_LOW_ENERGY);
            if(!Result)
            {
               Display(("LOW ENERGY Support initialized.\r\n"));
            }
            else
            {
               Display(("LOW ENERGY Support not initialized %d.\r\n", Result));
            }
...
        }
...
}

For additional details, you can refer to a dual-mode sample application (like the SPPLEDemo) from the SDK regarding how both BT classic and BLE are initialized.

Best regards,
