Problem sending an packet from Coordinator to End Device

Hi ,

like i was discussing in this thread http://e2e.ti.com/support/low_power_rf/f/158/p/17310/169314.aspx#169314

i am having problem to send menssage from coordinator to end device (or router) or like i realised, the probel is to receive message from the coordinator.

using the packet sniffer and the Daintree Network Analiser, i realised that i am sending the message correct (from 0x000 to broadcast), but it seems that i am not receiving it. 

I' m using the genericapp in this testing.

Im using the MessageMSGCB function, but it not working.

void GenericApp_MessageMSGCB( afIncomingMSGPacket_t *pkt )

{

  HalLcdWriteScreen( (char*)pkt->cmd.Data, "msg received" );

  switch ( pkt->clusterId )

  {

    case GENERICAPP_CLUSTERID:

      // "the" message

#if defined( LCD_SUPPORTED )

      HalLcdWriteScreen( (char*)pkt->cmd.Data, "rcvd" );

#elif defined( WIN32 )

      WPRINTSTR( pkt->cmd.Data );

#endif

      break;

  }

}

Do i need to use another interrupt, and not AF_INCOMING_MSG_CMD?

        case AF_INCOMING_MSG_CMD:

          GenericApp_MessageMSGCB( MSGpkt );

          break;

Or i need to send different from coordinator?

void GenericApp_SendTheMessage( void )

{

  char theMessageData[] = "Chikibumparatapau Giria de Pirata";

 

      GenericApp_DstAddr.addrMode = AddrBroadcast;

      GenericApp_DstAddr.addr.shortAddr = NWK_BROADCAST_SHORTADDR;

 

      if ( AF_DataRequest( &GenericApp_DstAddr, &GenericApp_epDesc,

                       GENERICAPP_CLUSTERID,

                       (byte)osal_strlen( theMessageData ) + 1,

                       (byte *)&theMessageData,

                       &GenericApp_TransID,

                       AF_DISCV_ROUTE, AF_DEFAULT_RADIUS ) == afStatus_SUCCESS )

  {

   osal_set_event(GenericApp_TransID, GENERICAPP_SEND_MSG_EVT);

   HalLcdWriteScreen( "WOOOOOW", "hehehhehe" );

    // Successfully requested to be sent.

  }

  else

  {

      HalLcdWriteScreen( "WOOOOOW", "ti peguei" );

    // Error occurred in request to send.

  }

}

 

Thanks for your attention

    Hi Franz, I same a similar problem,  I need to send a message from coordinator to end device, (first I send a message from end device to coordinator, now I have to process data and send new data to end device.. bidirectional communication), ¿how can I send the message from coordinator to end device?

    Dears,

    You can try to set a break point on zcl_event_loop() inside zcl.c. There is a statement like "if ( *msgPtr == AF_INCOMING_MSG_CMD )" and you can set the break point inside. Make sure you can receive the incoming message here first otherwise you can not receive it on you application.

    Regards!
