Danke paxi,

Ich gehe es mal auf diese weiße probieren.

Hey, I'm trying to figure out how I can get a response code from the esp8266. I made an app with App Inventor works very well but now I want to read the actual pin state so I can see in my App. Do have some experience with Arduino esp8266 but is new to me. I hope you can give me a tip. Thanks. Sorry...
