Hello,

I am using the CYBLE-0220001--00 module on PSoC 4.3. and I am developing an asset tracking product and there will be lots of assets in one place. My problem is that currently, I have set a local name by using CyBle_GapSetLocalName("Asset") function. But I want to advertise its local name identify by using the last 4 characters of MAC address like "Asset-A0B2" So that we can tag A0B2 on our product for further identification. Could you please help me to get the MAC address of my BLE I have tried below code but no expected result.

cyBle_deviceAddress.bdAddr[0] = CYBLE_SFLASH_DIE_X_REG;

        cyBle_deviceAddress.bdAddr[1] = CYBLE_SFLASH_DIE_Y_REG;

        // cyBle_deviceAddress.bdAddr[2] = CYBLE_SFLASH_DIE_WAFER_REG;

        // convert the values to ascii and store in the device name field.

        DeviceName[0] = ((cyBle_deviceAddress.bdAddr[1] & 0xF0) >> 4) + 48 ;

        DeviceName[1] = (cyBle_deviceAddress.bdAddr[1] & 0x0F) + 48 ;

        DeviceName[2] = ((cyBle_deviceAddress.bdAddr[0] & 0xF0) >> 4) + 48 ;

        DeviceName[3] = (cyBle_deviceAddress.bdAddr[0] & 0x0F) + 48 ;

If you can provide example code. it would be great.

Thanks in advance.

Regards.

Hi Neeraj,

You can use the API CyBle_GetDeviceAddress() to get the public address of the device.

CYBLE_GAP_BD_ADDR_T address;

                address.type =0x00;

        checkapiresult(CyBle_GetDeviceAddress(&address));

        printf("My public address is %x %x %x :%x %x %x  \r\n", address.bdAddr[5],address.bdAddr[4],address.bdAddr[3],address.bdAddr[2],address.bdAddr[1],address.bdAddr[0] );

Hope this helps !

Thanks

Ganesh

Hi Ganesh,

I have checked code and for checkapiresult function, I am getting error message it is undefined.

Could you please help me? where I can get function definition for checkapiresult?

Hi Neeraj,

Sorry. That is a custom function and I forgot to attach. You need to use a UARt component to print the result of that function return.

//BLE APIRESULT CHECK

void checkapiresult(CYBLE_API_RESULT_T apiResult)

{  

    switch ((uint8)apiResult)

    {

        case 0x00:

        UART_UartPutString("CYBLE_ERROR_OK\r\n");

        break;

       

        case 0x01:

        UART_UartPutString("CYBLE_ERROR_INVALID_PARAMETER\r\n");

        break;

       

        case 0x02:

        UART_UartPutString("CYBLE_ERROR_INVALID_OPERATION\r\n");

        break;

       

        default :

        printf("The API result is %x \r\n", apiResult);

        break;

    }

}

Thanks

Hello Ganesh,

Under the GAP settings tab Silicon generated "Company assigned" part of the device address option is Checked.

I can see BLE is started and able to find it on the nRF Connect app.

I am getting output:

My public address is 80 49 29 :19 95 80

Whereas my actual BLE MAC address is 00:a0:50:31:5a:24

80 49 29 :19 95 80 what is this?

Hi Ganesh,

Your solution works for me. The only important thing I was missing to make sure the above code should have executed after the CYBLE_EVT_STACK_ON event.

Thank you so much for your help.
