D. h. man spielt die sogenannte AT-Firmware auf, die durch Steuerkommandos (die komischerweise alle mit AT beginnen) konfiguriert wird, ohne jedes Mal neu programmiert werden zu m\u00fcssen. Wer jetzt glaubt, vom Regen in die Traufe zu kommen und AT Kommandos lernen zu m\u00fcssen, hat Gl\u00fcck, es gibt ein Gegenst\u00fcck f\u00fcr den Arduino. Ein paar Klassen erlauben es, den ESP mit einfachen Methodenaufrufen zu steuern, ohne die AT Kommandos verwenden zu m\u00fcssen. Somit sind die Ziele:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Installing the AT firmware on the ESP <\/li><li>Create a program on the Arduino which uses the ESP as a Wi-Fi adapter<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">HINWEIS: Schaut mal vorab, ob nicht schon die AT Firmware auf dem ESP vorhanden ist.
