      • 1. Re: How do I read the MAC address of my WICED Wi-Fi device?
        [applicable to SDK-2.x onwards]

         

        Information about the MAC address of the Wi-Fi device is here <WICED-SDK>/generated_mac_address.txt file.

         

        This file is auto-generated upon building a target.

         

         

        /*

         

        * The MAC address of the Wi-Fi device may be configured in one of several places :                               

         

        * 1. WLAN OTP   : The MAC address may be factory programmed into read-only OTP inside the Wi-Fi chip.            

         

        *                                                                                                                

         

        *                 directly into the application (which may be common to many devices).                           

         

        *                                                                                                                

         

        *      or         To force the WLAN chip to use the MAC addressed stored in the DCT, simply define               

         

        *    Custom       a global variable in your application makefile as shown below.                                 

         

        *                 In <WICED-SDK>/App/my_app/my_app.mk add the following global define :                          

         

        *                    GLOBAL_DEFINES := MAC_ADDRESS_SET_BY_HOST                                                      

         

        *                                                                                                                

         

        *                 To force the WLAN chip to use a custom MAC address (instead of the MAC address                 

         

        *                 in the DCT), simply redefine the host_platform_get_mac_address() function located in the file: 

         

        *                 <WICED-SDK>/Wiced/Platform/common/<MCU_ARCHITECTURE>/<MCU_PN>/<MCU_PN>_platform.c              

         

        */

         

         

        To read the mac address, use the API call : wiced_wifi_get_mac_addr().

         

        This is actually a lower-layer WWD (WICED Wi-Fi Driver) API, but is also available to customers.

         

        (We will expose this API in the high layer WICED API in a future version of the SDK)

          Hi

           

            Does it work with BCM4390 and SDK 1.3.1 ? 

            I have problem with BCM4390 and have some of compilation error

           

          Error console :

            If you do it with WiConnect; it is a single line...

             

            get wl m

             

            (as in get wlan mac)

             

             

            here is a screen shot from my console
