Hello,

I'm trying to setup my ESP8285 to connect to any available Wi-Fi network as described here: Connect Your ESP8266 To Any Available Wi-Fi network

However, whenever I verify the code, I get the below error:

'class ConfigManager' has no member named 'reset'

Here is my code:

#include <ArduinoJson.h>
#include <ESP8266WiFi.h>
#include <ConfigManager.h>
#include <PubSubClient.h> 
/******* Define Constants **********/ 
namespace{

    const char * TOKEN = "BBFF-BXutSWVNhBRDowrIHokq8OK9SXEk1S"; 
    // Assigns your Ubidots TOKEN 
    const char * DEVICE_LABEL = "Konnect"; 
    // Assigns your Device Label 
    const char * VARIABLE_LABEL = "my-variable"; 
    // Assigns your Variable Label

You have the wrong version of the ConfigManager library installed. The tutorial specifies that you must use the mariacarlinahernandez fork of the ConfigManager library, not the original nrwiersma library.

First, you must uninstall the incorrect library:

  • File > Examples > ConfigManager > save_config_demo
  • Sketch > Show Sketch Folder. This will open the folder containing the ConfigManager library's save_config_demo example sketch.
  • Navigate up three folder levels to the libraries folder.
  • Delete the ConfigManager folder (or similar name, depending on how you installed the library).

Next, you must install the correct library:

Now you should be able to compile the sketch without an error.

Thanks for your help, I've done that and I still encountered errors:

#define 1

^

Same code.

Did you modify the library? ConfigManager.h, line 5 is:

#define PIN_RESET 5

but in your installation, it is:

#define 1
5

Yeah, I did that.

If you want to change the reset pin to pin 1, the correct code is:

#define PIN_RESET 1
