    Failed to associated with a special Access Point

      Module: 4343W


      When joining an AP named CDW530AM, the return of host_rtos_get_semaphore is WWD_TIMEOUT, please refer the screenshot attached. The relevant code is below(WICED-SDK\WICED\WWD\internal\wwd_sdpcm.c):


         /* Wait till response has been received  */

          retval = host_rtos_get_semaphore( &wwd_sdpcm_ioctl_sleep, (uint32_t) WWD_IOCTL_TIMEOUT_MS, WICED_FALSE );


          if ( retval != WWD_SUCCESS )

              /* Release the mutex since wwd_sdpcm_ioctl_response will no longer be referenced. */

              host_rtos_set_semaphore( &wwd_sdpcm_ioctl_mutex, WICED_FALSE );

              return retval;



      The sniffer log named filter_with_mac_addr_60f1893e7335.pcap is also attached.


      However this issue is only met on this type Access point, the failed rate is also not 100% on this type Access point.
