RT，想看下具体改了哪些，对现有项目有无影响

应该不会的，一个走电源线一个走数据线

CMakeLists里面也添加了mqtt吗？

不重装的话，多尝试几次也能成功，感觉判定有问题

我也是，重装python解决了

If you are using Windows, you can shutdown the python alias.

Tell us how to do this.

In the Windows Settings, search "alias", then you will find how to shut.

跟串口OTA其实都是一样的，都是接收数据，写入，校验，修改boot这几步

If you are using Windows, you can shutdown the python alias. Because on Windows, python alias is linked to the Microsoft Store(I don't know why but it just do so). EIM will use python alias to check the python version, so it will fail any way when the alias is on.

esp_http_client_read() seems to do the work.

Could you help showing an example? I try to receive the data with this function but receive nothing.

Is there any best practice？
