ardiuno+ESP8266+DHT11将数据上传yeelink失败问题
各位大神，请教一个问题，我在测试网上提供的一个教程，它是一个用ardiuno+ESP8266+DHT11将数据上传yeelink的项目，链接是http://www.geek-workshop.com/forum.php?mod=viewthread&tid=11266&highlight=esp8266，发现使用教程提供的程序，使用它自己的APIKEY、设备号、传感器号可以将数据成功传到网上，但是将APIKEY、设备号、传感器号换成自己申请的，就无法将数据上传到网上，这是为什么呢？是不是yeelink的账户有权限设置，要升级之后才能将上传数据呢？下面两幅图是我的硬件连线图和ardiuno串口信息。 把程序贴上来。估计是长度计算错了。本帖最后由 木夕子 于 2015-8-4 11:49 编辑

估计找到问题所在了，int类型为16位二进制数，换成十进制就是－32768到32767，你看看你的DEVICEID和SENSORID都超过这个范围了。还有你看串口返回的信息里面的DEVICEID和SENSORID都成了什么了。
DEVICEID和Apikey对不上当然被拒绝了。
所以应该把void sendData(int device_id,int sensor_id,int thisData) 改成void sendData(long device_id,long sensor_id,int thisData)
long类型是-2,147,483,648到2,147,483,647
你再试试 APIKEY怎么看着也不对呀？#define APIKEY "902a3ee0022f77acee0a7cff24f38993" // replace your yeelink api key here和你上面贴图的APIKEY怎么不一样？

个人感觉就是APIKEY和DEVICEID以及SENSORID的问题。 mc.six 发表于 2015-8-5 08:44 static/image/common/back.gif

感谢大神的指点，将int改成long果然可以了，真是佩服的五体投地，也怪自己的C语言功底太差，真是惭愧啊！ mc.six 发表于 2015-8-5 08:44 static/image/common/back.gif

十分感谢大神的指点，将int改成long果然行得通了，真是眼泪都流出来，搞了这么多天，呵呵。万里长征终于走出第一步了，真是高兴。 mc.six 发表于 2015-8-5 08:44 static/image/common/back.gif

我也是个初学者，慢慢的一点一滴的学起来的，也没有学过C。o(∩_∩)o...哈哈！！！

OneNet也不错，可以试试。
