Update Library to work with WifiManager

[jkuhlm]

With the current library the WiFi SSID and password need to defined. It would be nice if Adafruit IO would work with WifiManager to fix this issue. Thanks

This issue is being actively developed in feature branch: https://github.com/adafruit/Adafruit_IO_Arduino/tree/dev-wifi-ap

Good news, thanks.

This issue is getting old, but I managed to use the two libraries at the same time by passing nullptr to both the ssid and pass arguments of AdafruitIO_WiFi / AdafruitIO_ESP8266.

Hi, any opportunity to change SSID and Password on the fly instead of using constants?

Maybe not ideal, but I think there’s a version of WiFimanager where you can put it in AP mode by pushing a button , then you could enter your new credentials .
For Adafruit_WiFi io(IO_USERNAME, IO_KEY, WIFI_SSID, WIFI_PASS) , change WIFI_SSID and WIFI_PASS to nullptr

Did anyone get this to work? When I set WIFI_SSID AND WIFI_PASS to nullptr my esp32 reboots and sets WifiManager back into AP mode.

This really needs to be fixed in the official library. Hard coding the SSID and KEY are fine for simple example and demo projects but not something you might want to share with others. I hacked around this as follows...

To allow wifimanager to handle the network connection and prevent Adafruit IO from conflicting the following lines were removed from the AdafruitIO_Wifi.cpp file...

also the class defintion was changed to remove the SSID and KEY and only use the IO_USERNAME and IO_KEY
in the .h and .cpp files for wifi/AdafruitIO_ESP8266....

public:
AdafruitIO_ESP8266(const char *user, const char *key);
~AdafruitIO_ESP8266();

Serial.println("here in Adafruit IO Code\n");
/*
delay(100);
commenting this out since we are already connected via wifimanager
WiFi.begin(_ssid, _pass);
delay(100);
_status = AIO_NET_DISCONNECTED;
*/

I found a better way to fix this. The hack I mention above removes the existing functionality which is not good. So instead, I overloaded the AdafruitIO_WiFi function so that it supports usage with SSSD+password and without. For example in AdafruitIO_ESP8266.h the prototypes look like this...

public:
AdafruitIO_ESP8266(const char *user, const char *key, const char *ssid,
const char *pass);
AdafruitIO_ESP8266(const char *user, const char *key);

In the implementation for the 2nd version, I set _ssid and _pass to NULL so that those can be checked to exclude the "connect" code.

@brentru - what are your suggestions on how we can get this concept included so that we can create projects without hard-coded wifi details?

Thanks!
