一、为什么要用最新的3.4
- 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
-
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
-
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

Cjson需要修改 pirnt_number函数
-
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);
