Danke für den Code,
ich habe auf meinem Server das arduino.php im root, die MAC habe ich an meinen ESP angepasst

Den compilierten .bin habe ich unter /bin auf dem Server liegen.
Den .bin habe ich "heizraum_messwerte_0.0.2.bin" genannt.
jetzt sollte die laufende Version 0.0.1 doch eigentlich auf die Version 0.0.2 geflasht werden?

Warum gibt das jetzt einen Code 500?
Der zu flashende ist doch eine Version neuer?
Mache ich da noch einen Gedankenfehler?
