最关注的后面的上云怎么还没有啊

看到一半教程了，不错

看了部分课程，端设备上Linux是不是大才小用了

坎坎坷坷

初步用过了liteos,需要深入学习

a. 在2020年HDC.Cloud上，你希望我们华为IoT展示哪些技术和内容？或者说你想学习了解华为IoT的哪些内容？为什么？ 因产品原因，接触了解了多家iot平台，华为iot在设备接入和管理，应用开发等方面有优势，尤其是oceanbooster使硬件出身的人在设计iot产品时受益匪浅，但目前iot平台与华为云其他产品的结合应用方面缺乏引导和教程，或者说对华为云的整体功能和应用没有全面深刻的理解，缺乏这方面深入浅出的教程，各种英语简称不知所云，而且各家随意定义而不统一，希望今后能有改进。

现在好用了，需要弄懂MDK的工程啊。程序中哪个地方设置为手动连接模式啊？

重新建的设备没有上线啊
