Working like a charm!!! ;D ;D ;D
Now, I also found WiFiManager and managed to test it. VERY practical for 'first time setup', without changing the code every time.
I will definitely useit, hence my question:
How do I reset the last SSID so to have the wifimanager go into ConnectionAP from my application on DUE?
If I understood correctly, if the last SSID is not found, manager goes into AP automatically. This is OK if I "move" my device from on place to another, with a different wifi network.
What if I simply want to connect to a different wifi?
I would like to have a push button on my arduino DUE that would force WiFiManager (included in WiFiSpiESP, who is running on my WeMos D1) to forget the last wifi and go into ConnectionAP.
