Ich habe versucht, den unteren Teil (ab Sektion "/*-------- NTP code ----------*/") in diese Lib zu verschieben, samt eigener #includes, dann klappt aber nichts mehr.
Die Fehlermeldungen vom Arduino-Compiler meldet noch nicht mal einen "richtigen" Fehler, nur einen
"exit status 1
Fehler beim Kompilieren für das Board NodeMCU 1.0 (ESP-12E Module)."
- welchen Teil muss ich wieder in das Hauptfile verschieben oder doppelt aufführen oder komplett zurückverschieben?

Ich habe versucht, den unteren Teil (ab Sektion "/*-------- NTP code ----------*/") in diese Lib zu verschieben, samt eigener #includes, dann klappt aber nichts mehr.
Die Fehlermeldungen vom Arduino-Compiler meldet noch nicht mal einen "richtigen" Fehler, nur einen
"exit status 1
Fehler beim Kompilieren für das Board NodeMCU 1.0 (ESP-12E Module)."
- welchen Teil muss ich wieder in das Hauptfile verschieben oder doppelt aufführen oder komplett zurückverschieben?
