Hallo Leute,
Ich habe folgendes Problem: Ich kann meinen ESP 8266 nicht mit meinen Wlan verbinden. Ich bekomme bei folgendem ersten scatch nur Punkte im seriellen monitor angezeigt oder bei dem 2Scatch steht nur dort das er zu verbinden versucht und dann die Verbindung nicht funktioniert hat, zeigt aber auch nicht warum 
. Nutze die Boardverwalterversion 2.2.0. Würde mich sehr freuen wenn mir jemand schnell antworten könnte. Scatch 1:
