How to check APS ack in TI Z-Stack

The following steps show you how to check APS ack in TI Z-Stack using ON/OFF cluster toggle command in SampleSwitch example.

1. Setup OnOffOptions and use zcl_registerClusterOptionList in  zclSampleSw_Init to register receiving APS ack on ZCL_CLUSTER_ID_GEN_ON_OFF cluster command.
   
    zclOptionRec_t OnOffOptions[] =
    {
      {
         ZCL_CLUSTER_ID_GEN_ON_OFF, ( AF_EN_SECURITY | AF_ACK_REQUEST ),
      },
    };
    ZStatus_t status = zcl_registerClusterOptionList ( SAMPLESW_ENDPOINT, 1,
                                                                                    OnOffOptions );
 2.  Add "case AF_DATA_CONFIRM_CMD:..." in SYS_EVENT_MSG case of zclSampleSw_event_loop

    uint16 zclSampleSw_event_loop( uint8 task_id, uint16 events )
    {
      ...
     
      if ( events & SYS_EVENT_MSG )
      {
        while ( (MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( zclSampleSw_TaskID )) )
        {
          switch ( MSGpkt->hdr.event )
          {
            case AF_DATA_CONFIRM_CMD:
              afDataConfirm_t *SWafDataConfirm;
              SWafDataConfirm = (afDataConfirm_t *)MSGpkt;
              rcv_aps_ack_trans_id=SWafDataConfirm->transID;
              // You can use rcv_aps_ack_trans_id to check if it matches to APS_Counter when you send toggle command with zclGeneral_SendOnOff_CmdToggle
              break;
     ...
