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);
        }
    
}

Hi !

The first step of debugging would be to know if the issue is coming from the wakeup routine or from the radio. Could you try to print through UART in your tx_service function and see if this function is correctly executed every second ?

Another good debugging step would be to see if the radio is actually transmitting any data or not. You can see this by enabling the PA and LNA pins in SysConfig, and checking with a logic analyser when those pins are high or low. If the radio is transmitting every second, then your PA pin should be high every second. You can read about how to enable the PA and LNA pins in the User Guide for the F3 SDK.

Hello, I have used the DEBUG to confirm that the program is fine. Next, I will follow the method you provided to confirm whether the PA pin is at a high level when sending RF data.

Thanks.

well，I added this function according to your instructions, and the oscilloscope showed that some of the RF data was indeed not sent. I guess it is a problem with the configuration struct. Can you provide a detailed configuration process for me to refer to？thank you.
