[参考译文] CC3235S：从接收模式切换到 WIFI 模式后出现未记录错误-14339

您好 Johann、

您可以在无线电工具中使用定义、因为这已经过测试。 sl_close 实际上是结束收发器模式的原因。

您使用的是哪种主机驱动程序/SDK 版本和服务包版本？

您好、Sarah、

我们将 SimpleLink SDK 5.10.00.02与 MAC 31.3.7.0.1、PHY 3.1.0.26、NWP 4.10.0.1、ROM 8738、主机3.0.1.71搭配使用。

此问题也会在 Launchpad 上发生、甚至更频繁。

下面是一些简化的测试代码：

static bool disconnect_from_wifi(void) {
    sem_wait(&network_connected);

    UART_PRINT("Disconnecting from Wifi\n");
    int ret = sl_WlanDisconnect();
    if (ret != 0 && ret != SL_ERROR_WLAN_WIFI_ALREADY_DISCONNECTED) {
        UART_PRINT("sl_WlanDisconnect failed: %d", ret);
        return false;
    }

    return true;
}

static bool connect_to_wifi(void) {

    SlWlanSecParams_t secParams = {0};
    secParams.Key = (signed char*)SECURITY_KEY;
    secParams.KeyLen = strlen(SECURITY_KEY);
    secParams.Type = SECURITY_TYPE;

    UART_PRINT("Connecting to Wifi\n");
    short retval = sl_WlanConnect((signed char *) SSID_NAME, strlen(SSID_NAME), 0, &secParams, 0);

    if (retval == 0) {
        return true;
    }

    if (retval == -14339) {
        UART_PRINT("sl_WlanConnect failed with %d. Retrying\n", retval);
        usleep(500000);
        // This recovers the issue *sometimes*. Other times, while it returns 0, the
        // SimpleLinkNetAppEventHandler will never be called with the SL_NETAPP_EVENT_*_ACQUIRED.
        retval = sl_WlanConnect((signed char *) SSID_NAME, strlen(SSID_NAME), 0, &secParams, 0);
        return retval == 0;
    }

    UART_PRINT("sl_WlanConnect failed with %d\n", retval);
    return false;
}

static void cw(void) {
    short socket = sl_Socket(SL_AF_RF, SL_SOCK_RAW, 6);

    if(socket < 0) {
        UART_PRINT("Error creating raw socket: %d\n", socket);
        return;
    }
    UART_PRINT("raw socket: %d, sending CW\n", socket);

    long send_result = sl_Send(socket, NULL, 0, 0);
    if (send_result < 0) {
        UART_PRINT("sl_Send returned %ld\n", send_result);
        return;
    }

    sleep(3);

    UART_PRINT("Sending CW STOP\n", socket);
    send_result = sl_Send(socket, NULL, 0, 128);
    if (send_result < 0) {
        UART_PRINT("Failed to send CW_STOP: %ld\n", send_result);
        sl_Close(socket);
        return;
    }

    short close_result = sl_Close(socket);
    if (close_result != 0) {
        UART_PRINT("Failed to close socket: %d\n", close_result);
    }
}


void test_error14339(void) {
    sem_init(&network_connected, 0, 0);

    connect_to_wifi();
    wait_for_network();

    while (1) {
        if (!disconnect_from_wifi()) {
            UART_PRINT("Failed to disconnect from wifi");
            while (1) {}
        }

        cw();

        if (connect_to_wifi()) {
            wait_for_network();
        } else {
            UART_PRINT("Failed to connect to wifi");
            while (1) {}
        }
    }
}

注意：我匆忙移植了信标相关代码、因此可能不是100%正确。 但总体结构应明确。

您好 Johann、

您能否在 LaunchPad 设置上收集 NWP 日志？ NWP 编程人员指南的调试部分中提供了相关说明。
