如何将WifiManager与Adafruit IO配合使用

Question

我正在使用Adafruit IO，并试图将其与WifiManager结合在一起，这样我就不必硬编码wifi凭据，但当我将wifi_sid和wifi_pass设置为null并依靠wifimager进行连接时，我会遇到此错误。当我设置凭据时，一切都很顺利。如何将adafruit IO与wifimanger一起使用？

AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, NULL, NULL);

使用当前或相对较新版本的AdafuitIO库，您可以这样调用以避免Adafuit库连接到WiFi。。。

AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, "", "");
