標(biāo)題: MQTT-relay-sdk-v21程序源碼
MQTT程序

單片機源程序如下:

  2. #include "stdlib.h"
  3. #include "stdint.h"
  4. #include "string.h"
  5. #include "system.h"

  7. #include "usart.h"
  8. #include "sim900a.h"
  9. #include "relay.h"
  10. #include "mqtt-user.h"
  11. #include "timer.h"
  12. #include "timer_task.h"
  13. #include "frozen.h"
  14. #include "parameter.h"
  15. #include "ctype.h"
  16. #include "MQTTPacket.h"

  18. /* 需要在這里更改服務(wù)器地址端口，用戶名密碼等信息 */
  19. /* 設(shè)備默認會將IMEI(SIM800C模塊上的標(biāo)號)設(shè)置為clientID */
  20. /*  */
  21. #define MQTT_SERVER_IP  "relay.mqtt.iot.gz.baidubce.com"
