问题描述

我目前正在尝试将我的 Sparkfun ESP8266 Thing 连接到我的 Azure IoT 中心.我已成功设置我的集线器,并且正在遵循有关如何将 Thing 连接到我的 Azure IoT 集线器的教程:https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-sparkfun-esp8266-thing-dev-get-started

I am currently trying to connect my Sparkfun ESP8266 Thing to my Azure IoT Hub. I have successfully set up my hub, and am following this tutorial on how to connect the Thing to my Azure IoT Hub: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-sparkfun-esp8266-thing-dev-get-started

不幸的是,我不断收到错误消息:

Unfortunately I keep getting the error:

'StaticJsonBuffer' 未在此范围内声明

我已将 DEVICE_ID 从SparkFun ESP8266 Thing Dev"更改为SparkFun ESP8266 Thing",并使用模拟数据.

I have changed the DEVICE_ID from "SparkFun ESP8266 Thing Dev" to "SparkFun ESP8266 Thing", and am using simulated data.

对此的任何帮助将不胜感激!

Any help with this would be much appreciated!

推荐答案

此错误的原因是您安装的 ArduinoJson 版本 >= 6.将安装默认版本 6.2.3-beta 但从版本 6和更高的 JsonBuffer 替换为 JsonDocument.它也在错误消息中指出:

The reason for this error is that you install the ArduinoJson version >= 6. Default version 6.2.3-beta will be installed but from version 6 and higher JsonBuffer is replaced with JsonDocument. It is also indicate in the error message:

要解决此问题,您可以回滚到以前的版本.5.13.2 版对我有用.

To solve this issue you can roll back to the previous version. Version 5.13.2 works for me.
