I have tow BCM943341WCD1 board, run with bt_dualmode_server example on wiced idk 3.7.0,  one is the server, and the other be a client. I use wiced_bt_dev_sec_bond(p_inq->remote_bd_addr, 0, BT_TRANSPORT_BR_EDR, 0, NULL) to initiate bonding to the server, but server returns:

your BT devices are the same BD address

I used  wiced_bt_set_local_bdaddr( dct_bt_config->bluetooth_device_address ) to change the bdaddr:

=============================================================================

if( p_event_data->enabled.status == WICED_BT_SUCCESS )

        {

            wiced_bt_dev_read_local_addr( bda );

            WPRINT_APP_INFO( ( "Local Bluetooth Address: [%02X:%02X:%02X:%02X:%02X:%02X]\n", bda[0], bda[1], bda[2], bda[3], bda[4], bda[5] ) );

#ifdef WICED_DCT_INCLUDE_BT_CONFIG

    {

        /* Configure the Device Address from the DCT */

         platform_dct_bt_config_t* dct_bt_config;

        wiced_dct_read_lock( (void**) &dct_bt_config, WICED_TRUE, DCT_BT_CONFIG_SECTION, 0, sizeof(platform_dct_bt_config_t) );

        WPRINT_APP_INFO( ("WICED DCT BT ADDR 0x%x:0x%x:0x%x:0x%x:0x%x:0x%x \r\n",

                dct_bt_config->bluetooth_device_address[0], dct_bt_config->bluetooth_device_address[1],

                dct_bt_config->bluetooth_device_address[2], dct_bt_config->bluetooth_device_address[3],

                dct_bt_config->bluetooth_device_address[4], dct_bt_config->bluetooth_device_address[5]) );

        wiced_bt_set_local_bdaddr ( dct_bt_config->bluetooth_device_address );

        wiced_dct_read_unlock( (void*) dct_bt_config, WICED_TRUE );

    }

#endif

Thanks! wiced_bt_set_local_bdaddr ( dct_bt_config->bluetooth_device_address ) really has no use.

===========================================================================

#ifdef WICED_DCT_INCLUDE_BT_CONFIG

    {

        /* Configure the Device Address from the DCT */

         platform_dct_bt_config_t* dct_bt_config;

        wiced_dct_read_lock( (void**) &dct_bt_config, WICED_TRUE, DCT_BT_CONFIG_SECTION, 0, sizeof(platform_dct_bt_config_t) );

        WPRINT_APP_INFO( ("WICED DCT BT ADDR 0x%x:0x%x:0x%x:0x%x:0x%x:0x%x \r\n",

                dct_bt_config->bluetooth_device_address[0], dct_bt_config->bluetooth_device_address[1],

                dct_bt_config->bluetooth_device_address[2], dct_bt_config->bluetooth_device_address[3],

                dct_bt_config->bluetooth_device_address[4], dct_bt_config->bluetooth_device_address[5]) );

        wiced_bt_set_local_bdaddr ( dct_bt_config->bluetooth_device_address );

        wiced_dct_read_unlock( (void*) dct_bt_config, WICED_TRUE );

    }

#endif

  wiced_bt_dev_read_local_addr( bda );

  WPRINT_APP_INFO( ( "New local Bluetooth Address: [%02X:%02X:%02X:%02X:%02X:%02X]\n", bda[0], bda[1], bda[2], bda[3], bda[4], bda[5] ) );

yankai​ It seems your local bluetooth address is not getting updated ?

Local bluetooth address is: 43:34

DCT has 0x51:0x34:

You call set_local_bdaddr() with DCT bd-addr as parameter and after you read it - it still reads the old-address of 43:34.

Can you confirm whether address changes are taking effect as intended ?

Can you also confirm what application you're using for client side ?

Thanks,
Dharam

Use program above it printed:

Local Bluetooth Address: [43:34:1B:00:1F:AC]

WICED DCT BT ADDR 0x51:0x34:0x20:0xaa:0xbb:0xcc

New local Bluetooth Address: [43:34:1B:00:1F:AC]

So wiced_bt_set_local_bdaddr ( dct_bt_config->bluetooth_device_address ) seems has no affect, and why?

But scan by other bluetooth device, the MAC address is changed ok.

My application is use two bluetooth device (BCM943341WCD1) to communicate  at high speed, and want to implement  by RFCOMM.

BCM943341WCD1 can paired with my phone, but the can't  pair  with  other BCM943341WCD1.

code:

wiced_bt_dev_read_local_addr( bda );
WPRINT_APP_INFO( ( "#########Local Bluetooth Address: [%02X:%02X:%02X:%02X:%02X:%02X]\n", bda[0], bda[1], bda[2], bda[3], bda[4], bda[5] ) );
bda[0] = 0x26;
bda[1] = 0x55;
WPRINT_APP_INFO( ( "#########Bluetooth Address will be changed to: [%02X:%02X:%02X:%02X:%02X:%02X]\n", bda[0], bda[1], bda[2], bda[3], bda[4], bda[5] ) );
wiced_bt_set_local_bdaddr ( bda );
wiced_bt_dev_read_local_addr( bda );
WPRINT_APP_INFO( ( "#########New local Bluetooth Address: [%02X:%02X:%02X:%02X:%02X:%02X]\n", bda[0], bda[1], bda[2], bda[3], bda[4], bda[5] ) );

as it run:

#########Local Bluetooth Address: [43:34:1B:00:1F:AC]

#########Bluetooth Address will be changed to: [26:55:1B:00:1F:AC]

#########New local Bluetooth Address: [43:34:1B:00:1F:AC]

I see a question on BCM4343w modules have the same Bluetooth MAC address says this bug, is this still a bug on WICED SDK 3.7.0?

yankai​ what you observed is strange. There had been a bug earlier(before 3.7.0, not sure which release exactly)where calling set_local_bdaddr() was updating the bluetooth mac-address as desired but when you read it using dev_read_local_addr() - it was returning the stale bluetooth-address controller was loaded with. It got fixed in subsequent releases.

The same fix had been present on 3.7.0 as well - but as you're still observing this bug, we will verify it and let you know.

On the issue of pairing fail issue - will you be able to provide application which you're using for Client-side? It is not clear what kind of connection your client is trying to establish with dual_mode server?( RFCOMM / GATT ? )

Thanks,
Dharam

My company wants a wifi & bluetooth module, and two modules is a pair. The wifi function is ready now, but bluetooth  with master and slave mode is stopped by pairing problem. The use of bluetooth like a bluetooth to UART converter. I use the example of bt_dualmode_server to test, and masked BLE function.

The difference between master and slave is the slave use wiced_bt_start_inquiry() to find master and initiate a bluetooth pairing, and bt_config_dct.h is modified as follows:

================================================================================

#define WICED_BLUETOOTH_DEVICE_NAME    "WICED Slave" //"WICED master"

#define WICED_BLUETOOTH_DEVICE_ADDRESS "\x28\x14\x20\x66\x7B\xCC"  //"\x51\x14\x20\x66\x7B\xCC"

#define WICED_BLUETOOTH_DEVICE_CLASS   "\x00\x1f\x00"

================================================================================

Is any bug in this program?

Thanks - it's more clear now. Problem could be in the client side app you're using or the bluetooth stack - can't say anything for sure. But as you've modified bt_dualmode_server application to use as client/server - can you post these files - so that we can give it a quick try?( assuming that won't be a problem)

I use bt_dualmode_server.7z as rfcomm server.

bt_dualmode_server_as_rfcomm_client.7z as rfcomm client.

yankai​ Did you attach these .7z packages anywhere ? I'm not able to find them.

Hello dkumar

How about the test result? Is any bug in my program? Can you pair success with two same boards?
