AliOS-Things 使用 MQTT

测试板

ESP8266 / MK3060

代码

AliOS-Things/example/mqttapp

修改

#define PRODUCT_KEY             "a1vuRZ5qR2q"
#define PRODUCT_SECRET          "dkbucklgoExQlRm0"
#define DEVICE_NAME             "SensorI"
#define DEVICE_SECRET           "BihxiHbiSZOzpptR6fzpJWuedZpoU5rJ"
// 添加user
/* These are pre-defined topics */
#define TOPIC_UPDATE            "/"PRODUCT_KEY"/"DEVICE_NAME"/user/update"
#define TOPIC_ERROR             "/"PRODUCT_KEY"/"DEVICE_NAME"/user/update/error"
#define TOPIC_GET               "/"PRODUCT_KEY"/"DEVICE_NAME"/user/get"
#define TOPIC_DATA               "/"PRODUCT_KEY"/"DEVICE_NAME"/user/data"

云端的操作

1.开通物联网套件
2.创建产品和设备
3.保存 ProductKey ，ProductSecret, DeviceName 和 DeviceSecret
4.定义 Topic ,并设置权限为”设备具有发布与订阅”

$(PRODUCT_KEY)/$(DEVICE_NAME)/user/data，
