標(biāo)題: 求助大佬Arduino一直報錯，未正確引用 WiFi 庫如何解決
arduino版本為2.3.4，開發(fā)板esp32-wroom-32e， ESP32-D0WD-V3 芯片。arduino重新下載安裝了幾次庫也是還是報這個錯誤如何解決
報錯內(nèi)容如下c:\Users\cxfqa\Documents\Arduino\libraries\ThingsCloud_ESP_SDK\src\ThingsCloudMQTT.cpp: In member function 'bool ThingsCloudMQTT::handleWiFi()':

開發(fā)板的庫不對。

有可能是庫版本不對，有一個笨笨的辦法，打開WiFi庫的示例，對比各個函數(shù)的使用方法，將程序中的函數(shù)改成示例中的用法。
