Hallo Zusammen
Ich versuche Temperaturdaten vom Dragino Lora Shield 868 MHz v1.4 welches aufgesteckt auf dem Aruino UNO ist auf das TTN network zu senden.
Hardware: Dragino Lora Shield 868 MHz v1.4 / Arduino UNO
Ich kann den Code nicht kompilieren und die untenstehende Fehlremeldung kommt. Mir ist nun nicht klar was ich im Code ändern muss damit es schlussentlich funktioniert.
Folgender Code habe ich verwendet:
