Hi,

der Code funktioniert bei mir wirklich super und nochmal vielen Danke für die Mühe. Jedoch frage ich mich wo die SSID und das dazugehörige Passwort gespeichert werden bzw. wie man diese auslesen kann.

Mfg Moritz

Super! Vielen Dank! Hat mit meiner Fritze 7490 auf Anhieb geklappt.

Hallo Ralf,

ich habe ein ESP32 Controller, hier gibt es die Funktion beginWPSConfig nicht, kannst Du mir hierbei helfen.

Im Voraus vielen Dank für Deine Bemühungen.

I created some code to use the flash button to connect to a wps access point.

When the flash button is pressed for longer than 3 seconds, the WPS sequence is initiated.

Also the blue led is used for status:
Short blinks: Disconnected
Fast blinks: Trying to connect to WPS station
Long blinks: Connected

Nach dem ich Tagelang auf Google gesucht habe,
hier die Lösung.

Mit meiner Fritz-box 7412 VDSL geht Push Button.

Danke an Ralf.
