ESP8266 RTOSSDK3.0 的工程同步到3.4

一、为什么要用最新的3.4

1. 因为ESP_IDF 4.4的 kconfig 和RTOS SDK的不兼容，我这里是想8266和32用同一个虚拟机，也不想各种折腾，所以就升级到3.4了

二、修改步骤

1. 注意看对应的GCC，这里匹配到的是 8.4.0，3.0的用5.2，2.x的用4.8 ，nonos也用4.8
   

2. smartconfig的start函数的参数有区别,sc回调去掉了，直接放到event里面去了
   3.0的SDK：

   ESP_ERROR_CHECK( esp_smartconfig_start(sc_callback) );
   

   3.4的SDK：

   smartconfig_start_config_t cfg = SMARTCONFIG_START_CONFIG_DEFAULT();
   ESP_ERROR_CHECK(esp_smartconfig_start(&cfg));
   

   具体参考smartconfig例子，这里IP WIFI SC事件，都注册到同一个回调里面去

      ESP_ERROR_CHECK(esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &event_handler, NULL));
      ESP_ERROR_CHECK(esp_event_handler_register(IP_EVENT, IP_EVENT_STA_GOT_IP, &event_handler, NULL));
      ESP_ERROR_CHECK(esp_event_handler_register(SC_EVENT, ESP_EVENT_ANY_ID, &event_handler, NULL));

3. Cjson需要修改 pirnt_number函数

4. mqtt需要使用url，不可以使用port和 host ,event handle可以和以前一样直接在config里面

    esp_mqtt_client_config_t mqtt_cfg = {

			//.uri = CONFIG_BROKER_URL,
    	    //.host = "xxxxxx",            //MQTT服务器IP
    		.uri = "mqtt://xxxxxxxxxx:1883",
    	    .event_handle = mqtt_event_handler, //MQTT事件
    	    //.port=1883,                         //端口
    	    .username = "3cXbC4LtLs21D3uHm77h",                //用户名
			.client_id = "4afd0a80-58cd-11ec-9209-b7aebb52f70b",
    	       // .password = "public",               //密码
        // .user_context = (void *)your_context
    };

    ESP_LOGI(TAG, "uri:%s\r\nusername:%s\r\nclient_id:%s\r\n",mqtt_cfg.uri,mqtt_cfg.username,mqtt_cfg.client_id);

    esp_mqtt_client_handle_t client = esp_mqtt_client_init(&mqtt_cfg);
    //esp_mqtt_client_start(client);
   // esp_mqtt_client_register_event(client, ESP_EVENT_ANY_ID, mqtt_event_handler, client);
    esp_mqtt_client_start(client);
