器件型号：LAUNCHXL-CC1312R1

工具与软件：

您好！

我正在开发 rfUARTBridge 演示 SDK 7_41_00_17 消息流 LAUNCHXL-CC1312R1 . 会自动重置 50kbps、25kHz 偏差、2-GFSK、100kHz RX 带宽 工作正常。但是此配置的速率不能满足我的需求、因此我需要更改为 200kbps、100kHz 偏差、2-GFSK、273kHz RX 带宽。 修改后、接收器只能接收数据一次并看到红灯亮起、串行端口打印接收到的数据。当发送端再次发射时、接收端不做出反应。

下面是我的一些参数：

和 rfUARTBridge.syscfg

顺便说一下、当我使用 Smart RF 连接使用相同的参数修改连接时、接收器可能会接收到不正确的数据

200kbps PHY 正在使用高级命令、因为它使用802.15.4g 数据包格式、并且您不能仅仅选择导出正常的 RX 和 TX 命令(它们设置不正确)。

如果您要使用200kbps PHY、则需要导入高级 RX 和 TX 命令、然后重新编写代码以使用这些命令。

您可以选择更改高级命令以使用与标准 RX 和 TX 命令相同的数据包格式进行 snd 和 receive、也可以选择保留默认的802.15.4g 数据包格式、并重新编写代码以支持这一点。

我强烈建议您查看 SDK 中的 rfDiagnostics 示例。

如果您查看 Radio_Builtin_ et52xTM 和 Radio_Builtin_ 384etRx 函数中的 radio.c 文件、您将看到需要如何更改命令和/或代码以支持"正常"数据包格式(TEST_RF_PERF)或802.15.4g 数据包格式(TEST_STUDIO_COMPL)：

你好、Siri、

感谢您的帮助。参考了 rfDiagnostics 示例并在 rfUARTBridge 演示中修改一些数据包格式后、我终于解决了问题。顺便提一下、我还有其他问题要问您。

我想使用射频回调来执行该操作 rf_runCmd -->发送数据包--> txCallback (发送数据包完成)-->发送数据包... 课程、您似乎已经回答过类似这样的问题： https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1104727/cc1311p3-how-to-setup-rf-callback-function?tisearch=e2e-sitesearch&keymatch=RF_runCmd%25252525252525252520callback#

尽管我已经查看过 RF_runCmd ()函数和 RF_CMD Core_Events、但我在实际使用中仍然有问题。回调函数似乎未按预期进入。这种现象是绿光翻转一次、红光不翻转

下面是我的函数：

/* Callback function called when data is received via RF
 * Function copies the data in a variable, packet, and sets packetRxCb */
void TxOnRFcallback(RF_Handle h, RF_CmdHandle ch, RF_EventMask e)
{

         if (e & RF_EventTxDone)
    {
        GPIO_toggle(CONFIG_GPIO_RLED);
       packetTxCb = PACKET_TXED;
    }
}

void *mainThread(void *arg0)
{
    packetTxCb = PACKET_TXED;

    RF_Params rfParams;
    RF_Params_init(&rfParams);

    GPIO_setConfig(CONFIG_GPIO_RLED, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
    GPIO_write(CONFIG_GPIO_RLED, CONFIG_GPIO_LED_OFF);

    GPIO_setConfig(CONFIG_GPIO_GLED, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
    GPIO_write(CONFIG_GPIO_GLED, CONFIG_GPIO_LED_OFF);


    RF_cmdPropTxAdv.pPkt = packet;
    RF_cmdPropTxAdv.pktLen = sizeof(packet);
    RF_cmdPropTxAdv.startTrigger.triggerType = TRIG_NOW;



    /* Request access to the radio */
    rfHandle = RF_open(&rfObject, &RF_prop, (RF_RadioSetup*)&RF_cmdPropRadioDivSetup, &rfParams);

    /* Set the frequency */
    RF_postCmd(rfHandle,(RF_Op*)&RF_cmdFs, RF_PriorityNormal, NULL, 0);


                                                           0 );

    while(1)
    {
        if(packetTxCb)
        {
            /* config pactet */
            
            /*Send packet*/
            RF_runCmdSafe(rfHandle, (RF_Op*)&RF_cmdPropTxAdv, RF_PriorityNormal, &TxOnRFcallback, RF_EventTxDone | RF_EventLastCmdDone);
            /* Toggle green led to indicate TX */
            GPIO_toggle(CONFIG_GPIO_GLED);

             packetTxCb = NO_PACKET;

        }
}

可以帮助我解决我的问题吗？

我不确定您在代码中执行的具体操作及其原因、我无法在射频驱动器中的任何位置找到 RF_runCmdSafe。

运行专有命令时、下面的列表显示了产生的中断：

如您所见、您无法使用 RF_EventTxDone、因为它仅用于 BLE 和 IEEE。

如果您使用的是 RF_EventLastCmdDone、您将在完成 TX 命令后获得回调。

我在对 rfUartBrigde 示例进行以下修改后测试了以下内容：

static void ReceivedOnRFcallback(RF_Handle h, RF_CmdHandle ch, RF_EventMask e);
static void ReceiveonUARTcallback(UART2_Handle handle, void *buffer, size_t count, void *userArg, int_fast16_t status);
static void Txcallback(RF_Handle h, RF_CmdHandle ch, RF_EventMask e); // Added callback function for TX

if (bytesReadCount != 0)
{
    /*The packet length is set to the number of
     * bytes read by UART2_read() */
    RF_cmdPropTx.pktLen = bytesReadCount;
    int i;
    for (i=0; i<bytesReadCount; i++)
    {
        uint8_t* buffer8 = (uint8_t*) input;
        packet[i] = buffer8[i];
    }

    /*Cancel the ongoing command*/
    RF_cancelCmd(rfHandle, rfPostHandle, 1);

    /*Send packet*/
    RF_runCmd(rfHandle, (RF_Op*)&RF_cmdPropTx, RF_PriorityNormal, &Txcallback, RF_EventLastCmdDone); // Added callback

    /* Toggle green led to indicate TX */
    GPIO_toggle(CONFIG_GPIO_GLED);

    /* Resume RF RX */
    rfPostHandle = RF_postCmd(rfHandle, (RF_Op*)&RF_cmdPropRx, RF_PriorityNormal, &ReceivedOnRFcallback, RF_EventRxEntryDone);
    bytesReadCount = 0;

    /* Resume UART read */
    status = UART2_read(uart, &input, bytesToRead, NULL);
}

void Txcallback(RF_Handle h, RF_CmdHandle ch, RF_EventMask e)
{
    if (e & RF_EventLastCmdDone)
    {
        GPIO_toggle(CONFIG_GPIO_RLED);
    }
}

你好、Siri、

rf_runCmdSafe 函数是 rfDiagnostics 示例的 radio.c 中的函数。感谢您让我确认我应该使用 RF_EventLastCmdDone 提供一个路径。

至于我的问题、我还发现原因是、我修改了 packetTxCb、并且处于一个不合适的位置、这会导致环路永远不会进入
