Question

我正在尝试将esp8266设备连接到azure IOT集线器，据我了解，方法是使用正式的AzureIoThub库（在库管理器中分发），但是为什么包含此库的任何代码都没有编译。

添加库后出现以下错误。

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Answer 2

您可能遇到以下类似问题： https://github.com/arduino/Arduino/issues/7930

原来是固定于arduino-builder的： https://github.com/arduino/arduino-builder/pull/285

Answer 3

This post可能是解决方案。

基本上编辑.\Arduino15\packages\esp8266\hardware\esp8266\2.6.3\platform.txt，使其具有以下行：

build.extra_flags=-DESP8266 -DDONT_USE_UPLOADTOBLOB -DUSE_BALTIMORE_CERT

Answer 4

在build.extra_flags=前一行的文件platform.txt中有一个重要提示：
＃可以在boards.txt中覆盖

使用通用8266板，我必须按如下所示修改文件board.txt中的build.extra_flag才能编译Azure示例：

generic.menu.CrystalFreq.40.build.extra_flags=-DF_CRYSTAL=40000000 -DESP8266 -DDONT_USE_UPLOADTOBLOB -DUSE_BALTIMORE_CERT

在esp8266设备上未使用Include AzureIoThub.h编译代码
