Hi TI,

我用CC3200SDK_1.3.0上的MQTT_client，然後在windows上用mosquitto去開一個broker，

並把設定

/*Defining Broker IP address and port Number*/
#define SERVER_ADDRESS "10.35.81.14"
#define PORT_NUMBER 1883

可是執行程式會發生Broker connect fail for conn no. 1

請問是哪邊有誤導致的?要怎樣修改成能成功連線到mosquitto的Broker呢?

請教教我一下，謝謝!

您可以参考下E2E上的帖子 https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968/t/417213
在main.c中修改了usr_connect_config
char *security_file_list[] = {"/cert/clientkey.der", "/cert/clientcrt.der", "/cert/cacrt.der"};connect_config usr_connect_config[] = 
{ 
    { 
        { 
            { 
                SL_MQTT_NETCONN_SEC,  //SL_MQTT_NETCONN_URL 
                SERVER_ADDRESS, 
                PORT_NUMBER, 
        SL_SO_SEC_METHOD_SSLv3_TLSV1_2, 
        SL_SEC_MASK_SECURE_DEFAULT, 
                3, 
        security_file_list 
            }, 
            SERVER_MODE, 
            true, 
        }, 
        NULL, 
        "user1", 
        NULL, 
        NULL, 
        true, 
        KEEP_ALIVE_TIMER, 
        {Mqtt_Recv, sl_MqttEvt, sl_MqttDisconnect}, 
        TOPIC_COUNT, 
        {TOPIC1, TOPIC2, TOPIC3}, 
        {QOS2, QOS2, QOS2}, 
        {WILL_TOPIC,WILL_MSG,WILL_QOS,WILL_RETAIN}, 
        false 
    } 
};

请注意MQTT连接的时候有没有enable SSL, 你默认创建的mosquitto是没有SSL连接的吧。你需要在mqtt client上disable SSL.
