使用WIFI Shield V3上传温湿度到YEELINK，yeelink无数据
弄了很久都没有弄好，现在只能找大家帮忙了，折腾好几个晚上了程序：
#include <dht11.h>
dht11 DHT;
float TEMP;
int HUMI;
int thisLength;
int time=0;
void setup()
{
Serial.begin(115200);
pinMode(13,OUTPUT);
}
void loop()
{
int chk = DHT.read(4);
TEMP = DHT.temperature;
HUMI = DHT.humidity;
TEMP = (int(TEMP * 100.0)) / 100.0;
char tempStr;
floatToString(TEMP,tempStr);
String data;
data+="";
data+=String(tempStr);
int t=data.length();
time=time+1;
if (time%2==1)
{
Serial.println("POST http://api.yeelink.net/v1.0/device/14899/sensor/25567/datapoints/add");
Serial.println("Host: api.yeelink.net");
Serial.print("Accept: *");
Serial.print("/");
Serial.println("*");
Serial.print("U-ApiKey: ");
Serial.println("9d2b482044dfaa42ad59806af17ae5c3"); // 此处用你的APIKEY替代
Serial.print("Content-Length: ");
int thislength=17+t;
Serial.println(thislength);
Serial.println("Content-Type: application/x-www-form-urlencoded");
Serial.println("Connection: close");
Serial.println();
Serial.print("params={\"value\":");
Serial.print(TEMP);
Serial.println("}");
delay(1000);
digitalWrite(13,LOW);
delay(5000);
}
else if(time%2==0)
{

}
}
int getLength(int someValue) {
// there's at least one byte:
int digits = 1;
// continually divide the value by ten,
// adding one to the digit count for each
// time you divide, until you're at 0:
int dividend = someValue /10;
while (dividend > 0) {
dividend = dividend /10;
digits++;
}
// return the number of digits:
return digits;
}
void floatToString(float in,char* out){
uint16_t Tc_100 = in*100;
uint8_t whole, fract;
whole = Tc_100/100 ; // separate off the whole and fractional portions
fract = Tc_100 % 100;
sprintf(out,"%d.%d",whole,fract);
delay (10000);
}

下面是wifi sheild的设置界面的截图，连续好几天都折腾到深夜，还是无果，求大家帮忙看一下
YEELINK界面
POST 后面不用加 http://api.yeelink.net试试 本帖最后由 Youyou 于 2014-10-22 16:54 编辑
试试这段代码：
//没有传感器，上传一个循环的1-10的数字
int i;
//for yeelink api
#define APIKEY "*******" //改为自己的
#define DEVICEID **** //改为自己的
#define SENSORID ****//改为自己的
void postData(int thisData) {
Serial.print("POST /v1.0/device/");
Serial.print(DEVICEID);
Serial.print("/sensor/");
Serial.print(SENSORID);
Serial.print("/datapoints");
Serial.println(" HTTP/1.1");
Serial.println("Host: api.yeelink.net");
Serial.print("Accept: *");
Serial.print("/");
Serial.println("*");
Serial.print("U-ApiKey: ");
Serial.println(APIKEY);
Serial.print("Content-Length: ");
int thisLength = 10 + getLength(thisData);
Serial.print(thisLength);
Serial.println();
Serial.println("Content-Type: application/x-www-form-urlencoded");
Serial.println();
Serial.print("{"value":");
Serial.print(thisData);
Serial.println("}");
}
int getLength(int someValue) {
int digits = 1;
int dividend = someValue /10;
while (dividend > 0) {
dividend = dividend /10;
digits++;
}
return digits;
}
void setup(){
Serial.begin(115200);
}
void loop() {
for(i=1;i<10;i++){
postData(i);
delay(5*1000);
}
}

买了什么板呢？试了有用我也去买！seeeduino的板和wifi都太难懂了，网上的例程都找不到 caihuiwei 发表于 2014-10-23 20:32
