STM32F103通过ESP8266WIFI使用TCP透传协议连接至移动ONENET实现远程控制LED灯

1. 硬件设备：STM32F103RCT6开发板， ATK-ESP8266wifi模块
2. 软件开发环境：Keil5

一：ONENET平台配置
1.注册产品及添加设备


2.上传lua脚本
可从onenet平台上下载demo，脚本中最重要的两个函数，根据需要修改，本例子中，只是把上传的数据解析为Distance数据存在onenet平台上，没收到一包数据，就返回给终端一个received字符串。


3.创建应用





二：STM32代码开发

1. WIFI 连接至onenet代码

char esp8266_init()
{
	char * ok = "OK";
	char * at = "AT\r\n";
  char * at_cwmode = "AT+CWMODE=1\r\n";
  char * at_rst = "AT+RST\r\n";
  char * at_cifsr = "AT+CIFSR\r\n";
  char * at_cipmux = "AT+CIPMUX=0\r\n";
  char * at_cipmode = "AT+CIPMODE=1\r\n";
  char * at_cipstart = "AT+CIPSTART=\"TCP\",\"183.230.40.40\",1811\r\n";
  char * at_cipsend = "AT+CIPSEND\r\n";
	char at_cwjap[64];
	memset(at_cwjap, 0, sizeof(at_cwjap));
	strcat(at_cwjap,"AT+CWJAP=\"");
	strcat(at_cwjap,WIFI_SSID);
	strcat(at_cwjap,"\",\"");
	strcat(at_cwjap,WIFI_KEY);
	strcat(at_cwjap,"\"\r\n");
	
	
  while(esp8266_send_at(at, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cwmode, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_rst, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cwjap, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cifsr, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cipmux, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cipmode, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cipstart, ok)){
    delay_ms(1000);
  }
  while(esp8266_send_at(at_cipsend, ok)){
    delay_ms(1000);
  }

	onenet_tcp_regist();
  printf("Connect to onenet success\r\n");
	
	return 0;
}

2.解析onenet下发命令代码

void keep_connect_onenet()
{
	char temp[12];
	char info = 0;
	memset(temp, 0, sizeof(temp));
	sprintf(temp, "%d", rand()%100);
	USART1_Send_Data(temp, strlen((const char *)temp));
	//处理onenet下发的信息
	delay_ms(500);
	if(URecv_Index){
		if(strstr(URecv, "received")!=NULL){
			printf("upload data to onenet ok\r\n");
			info++;
		}
		if(strstr(URecv, "LED_ON")!=NULL){
			printf("get onenet cmd  LED_ON\r\n");
			led_turn_on();
			info++;
		}
		if(strstr(URecv, "LED_OFF")!=NULL){
			printf("get onenet cmd  LED_OFF\r\n");
			led_turn_off();
			info++;
		}
		if(info){
			URecv_Index = 0;
			memset(URecv, 0, sizeof(URecv));
		}
	}
}
