请求的地址在浏览器中可以用 211.149.219.61:8010/api/data?value=eeeeeeuuuio

请大神们指点迷津。谢谢

停止工作是不是防止内存溢出？

说一句外行话，是不是他的自我工作机制？应该分辩一下是停止工作还是死机！

我测试了一下, 其实 " HTTP/1.1"可以完全去掉, 就可以正常工作了

LZ的服务器段用的是WebAPI,是怎么看出来的?

可以试试降低波特率，加大通讯间隔等方式降低wido负载、避免通信口堵塞

感谢二位的答复，问题已经解决，问题出在get 传参数最后一个参数，实例代码给的默认是 HTTP/1.1,实际我服务器段用的是WebAPI，所以改成HTTPAPI/2.0 功能就实现了。但是目前测试感觉WidDo并不稳定，在单独加电（5V 1A）运行数个小时以后就停止工作。用USB接电脑串口监视，监视了一段时间串口也会停止接受数据。我个人感觉是硬件问题，想问问各位WIDO的稳定情况如何？？？？？

恩，说得对，“error400是请求出错
由于语法格式有误，服务器无法理解此请求。不作修改，客户程序就无法重复此请求”

看反馈是你的服务器已经链接，有反馈数据，但是你的service并没有正确响应wido的request。建议自己看看webservice里的调用格式。

通信格式是什么？看反馈是完全没连上啊。先试试能否连上wifi，再试通信协议是否正确
