RTOS/CC1310: CC130 WOR example

My purpose is based on wireless wake-up reception，return the received data.If i use this way，whether or not the data is received, it will execute the TX command per 500ms seconds.

 /*my add*/
    RF_cmdPropRxSniff.pktConf.bRepeatOk = 0;
    RF_cmdPropRxSniff.pktConf.bRepeatNok = 1;  
    RF_cmdPropRxSniff.pNextOp = (rfc_radioOp_t *)&RF_cmdPropTx;
    /* Only run the TX command if RX is successful */
    RF_cmdPropRxSniff.condition.rule = COND_STOP_ON_FALSE;
    
    RF_cmdPropTx.pktLen = 30;
    RF_cmdPropTx.pPkt = txPacket;
    RF_cmdPropTx.startTrigger.triggerType = TRIG_REL_PREVEND;
    RF_cmdPropTx.startTime = TX_DELAY;
  /*my add*/

I want to achieve is to execute the data only when the data is received.The core issue is how to choose a suitable trigger condition for sending commands.
If not, how can I achieve the switch between receiving and transmitting data?
