CC2340R5: Some questions about implementing the sending of ADV data on the rfPacketTx routine of the CC2340R5 chip

When using the rfPacketTx routine, I discovered an issue. I set a wake-up time of 1 second, and after waking up, data will be automatically sent. However, there is a possibility that this data may not be sent.

Below is my code for this part, along with a picture of the issue.

//
void tx_cfg(void)
{
    /* Initialize and open RCL */
    RCL_init();
    Display_init();
    display = Display_open(Display_Type_UART, NULL);

    rclHandle = RCL_open(&rclClient, &LRF_config);
    /* Set RF frequency */
    rclPacketTxCmdGenericTx.rfFrequency = FREQUENCY_chl37;

    /* Start command as soon as possible */
    rclPacketTxCmdGenericTx.common.scheduling = RCL_Schedule_Now;
    rclPacketTxCmdGenericTx.common.status = RCL_CommandStatus_Idle;

    rclPacketTxCmdGenericTx.config.fsOff = FS_OFF; // Turn off FS

    /* Callback triggers on last command done */
    rclPacketTxCmdGenericTx.common.runtime.callback = txCallback;
    rclPacketTxCmdGenericTx.common.runtime.rclCallbackMask.value = RCL_EventLastCmdDone.value;
}


void tx_service(void)
{
 
        uint8_t *txData;
        
        RCL_Buffer_TxBuffer *txPacket = (RCL_Buffer_TxBuffer *)&packet_t;
        txData = RCL_TxBuffer_init(txPacket, 0, 0, 25);
        
        sendbuf_debug[24] = packet_cnt;
        /* Generate a random payload */
        memcpy(txData,sendbuf_debug,25);

        /* Set packet to transmit */
        RCL_TxBuffer_put(&rclPacketTxCmdGenericTx.txBuffers, txPacket);

        rclPacketTxCmdGenericTx.common.status = RCL_CommandStatus_Idle;

        /* Submit command */
        RCL_Command_submit(rclHandle, &rclPacketTxCmdGenericTx);
    
         /* Pend on command completion */
        RCL_Command_pend(&rclPacketTxCmdGenericTx); 
    
        if(send_cnt>=3)
        {
            send_cnt = 0;
            packet_cnt++;
            usleep(PACKET_INTERVAL);
        }
    
}
