how to use NLME_DirectJoinRequest ？

Other Parts Discussed in Thread: Z-STACK

Hi  all 

        i am try  to follow the swru124a Document note for Using the Direct Join Request Feature in Z-Stack （ NLME_DirectJoinRequest（））。

        step1：i change the devStartMode define  in  the ZDApp.c file:

#if ( ZG_BUILD_RTRONLY_TYPE ) || ( ZG_BUILD_ENDDEVICE_TYPE )
  #ifdef DIRECTJOIN
        devStartModes_t devStartMode = MODE_RESUME;
  #else
        devStartModes_t devStartMode = MODE_JOIN;  
  #endif 
#else
  devStartModes_t devStartMode = MODE_HARD;
#endif

         step2 : change the ZDAppDetermineDeviceType function

if ( nwk_ExtPANIDValid( AIB_apsUseExtendedPANID ) == false )
    {
#ifdef DIRECTJOIN
      devStartMode = MODE_RESUME;
#else
      devStartMode = MODE_JOIN;     // Assume joining
#endif 
    }

        step 3:   add the  NLME_DirectJoinRequest（） in  coordinator side

void HandleKeys( uint8 keys )
{
    if( keys & HAL_KEY_SW_0 )
   {    
    unsigned char device_address[8] = {0x00, 0x12, 0x4B, 0x00, 0x07, 0x71, 0x79, 0x70}; 
    ZStatus_t state;
    HalLedBlink ( HAL_LED_1,10,50,200);
    state = NLME_DirectJoinRequest( device_address, CAPINFO_DEVICETYPE_RFD );
   }
}

       step4：power on the coordinator， and then press the key ， i saw the LED blink ，and  return state value is  ZSUCCESS

       but  i have  not seen anything  in  the ubiqua windows~~~~~

        Q1  :  is that mean coordinator  would not send out anything  while execute the  NLME_DirectJoinRequest（）

        Step 5：

        when the end device power on，  it send  out a  orphan notification  then always send beacon request  and  could not  join the network。

         Q2  so  what is wrong of my test ？ 

           WHY  End device could  not  join  the network  in this mode？

BR!
