STM32F103通過ESP8266WIFI使用TCP透傳協議連接至移動ONENET實現遠程控制LED燈

1. 硬件設備：STM32F103RCT6開發板， ATK-ESP8266wifi模塊
2. 軟件開發環境：Keil5

一：ONENET平臺配置
1.註冊產品及添加設備


2.上傳lua腳本
可從onenet平臺上下載demo，腳本中最重要的兩個函數，根據需要修改，本例子中，只是把上傳的數據解析爲Distance數據存在onenet平臺上，沒收到一包數據，就返回給終端一個received字符串。


3.創建應用





二：STM32代碼開發

1. WIFI 連接至onenet代碼

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下發命令代碼

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));
	//處理onenet下發的信息
	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));
		}
	}
}
