idf版本:4.4
esp版本:esp32-wroom-32
我在使用esp32读取dht11模块的数据,使用mqtt上传到阿里云时发生重启,没有找到问题

我创建了一个Task任务 get_dht11(),每次执行到esp_mqtt_client_publish这里就报上面的错误

Code: [Select all] [Expand/Collapse]

static char my_topic[50] = "/sys/%s/%s/thing/event/property/post";

void get_dht11(void * pClient){
    int dht11_status;
    float temperature;
    float humidity;
    unsigned int loopTimes = 1;
 
    static char MY_TOPIC_COMPONENTS[64] = {0};
    snprintf(MY_TOPIC_COMPONENTS, sizeof(MY_TOPIC_COMPONENTS),my_topic , EXAMPLE_PRODUCT_KEY,EXAMPLE_DEVICE_NAME);
 
    char MY_TOPIC_PUBLISH_COMPONENTS[200] = {0};
    int msg_id;
    //portMUX_TYPE mmux = portMUX_INITIALIZER_UNLOCKED;
    while (1)
        {
            if(mqtt_link_status == true){
                dht11_status = DHT11_read();
                ESP_LOGI(TAG, "loopTimes:%d \n",loopTimes++);
 
                 if(dht11_status == DHT_SUCCESS){
                    temperature = humidity = 0;
                    temperature = get_temperature();
                    humidity = get_humidity();

                    memset(MY_TOPIC_PUBLISH_COMPONENTS, 0, 200);

                 }
            }
            vTaskDelay(DHT11_TASK_DELAY / portTICK_PERIOD_MS);
        }
 
}
